Эта страница описывает особенности G-кодов, которые используются в прошивках принтеров RepRap, и как они работают. Основной целью является аддитивное производство с использованием процессов FFF (производство расплавленным филаментом). Коды для движения печатающей головки придерживаются стандарта G-кода NIST RS274NGC, поэтому прошивки RepRap вполне пригодны для ЧПУ фрезерования и также для аналогичных приложений. См. также Wikipedia's G-code article.
Существует несколько различных способов подготовки G-кода для принтера. Один из способов заключается в использовании программы слайсинга, например Slic3r, Skeinforge или Cura. Эти программы импортируют модель САПР, разрезают ее по слоям и выводят G-код, требуемый для печати каждого слоя. Slicers are the easiest way to go from a 3D model to a printed part, however the user sacrifices some flexibility when using them. Another option for G-code generation is to use a lower level library like mecode. Libraries like mecode give you precise control over the tool path, and thus are useful if you have a complex print that is not suitable for naive slicing. The final option is to just write the G-code yourself. This may be the best choice if you just need to run a few test lines while calibrating your printer.
As many different firmwares exist and their developers tend to implement new features without discussing strategies or looking what others did before them, a lot of different sub-flavours for the 3D-Printer specific codes developed over the years. This particular page is the master page for RepRap. Nowhere in here should the same code be used for two different things; there are always more numbers to use... The rule is: add your new code here, then implement it.
Unfortunately human nature being what it is, the best procedures aren't always followed, so some multiple uses of the same code exist. The rule which should be followed is that later appearances of a code on this page (later than the original use of a code), are deprecated and should be changed, unless there is a good technical reason (like the general G-Code standard) why a later instance should be preferred. Note that the key date is appearance here, not date of implementation.

Введение
Типичный фрагмент G-кода, отправленный на RepRap устройство, может выглядеть следующим образом:
N3 T0*57 N4 G92 E0*67 N5 G28*22 N6 G1 F1500.0*82 N7 G1 X2.0 Y2.0 F3000.0*85 N8 G1 X3.0 Y3.0*33
G-code can also be stored in files on SD cards. A file containing RepRap G-code usually has the extension .g
, .gco
or .gcode
.
Files for BFB/RapMan have the extension .bfb
.
G-code stored in file or produced by a slicer might look like this:
G92 E0 G28 G1 F1500 G1 X2.0 Y2.0 F3000 G1 X3.0 Y3.0
The meaning of all those symbols and numbers (and more) is explained below.
Slicers will (optionally?) add G-code scripts to the beginning and end of their output file to perform specified actions before and/or after a print such as z-probing the build-area, heating/cooling the bed and hotend, performing ooze free "nozzle wipe" startup routine, switching system power on/off, and even "ejecting" parts. More info on the Start GCode routines and End GCode routines pages.
To find out which specific G-code(s) are implemented in any given firmware, there are little tables attached to the command descriptions, like this one:

Это означает:
- {{Да}}
- G-код полностью поддерживается прошивкой.
- {{Частично}} или {{Экспериментально}}
- There is some support for the G-code. Often it is required to check out the source code branch for the firmware (usually stored in a different branch) or to flip configuration switches on the mainboard.
- {{Автоматически}}
- The firmware handles this G-code automatically, so there's no need to send the command. An example is power supply on/off G-code (M80/M81) in the Teacup firmware.
- {{???}}
- It is unknown if the firmware supports this G-code. You may want to test this yourself before using it in production.
- {{no}}
- The firmware does not support this G-code.
For the technically-minded, G-code line endings are Unix Line Endings (\n
), but will accept Windows Line Endings (\r\n
), so you should not need to worry about converting between the two, but it is best practice to use Unix Line Endings where possible.
Fields
A RepRap G-code is a list of fields that are separated by white spaces or line breaks. A field can be interpreted as a command, parameter, or for any other special purpose. It consists of one letter directly followed by a number, or can be only a stand-alone letter (Flag). The letter gives information about the meaning of the field (see the list below in this section). Numbers can be integers (128) or fractional numbers (12.42), depending on context. For example, an X coordinate can take integers (X175
) or fractionals (X17.62
), but selecting extruder number 2.76 would make no sense. In this description, the numbers in the fields are represented by nnn
as a placeholder.
In RepRapFirmware, some parameters can be followed by more than one number, with colon used to separate them. Typically this is used to specify extruder parameters, with one value provided per extruder. If only one value is provided where a value is needed for each extruder, then that value is applied to all extruders.
Letter | Meaning |
---|---|
Gnnn | Standard G-code command, such as move to a point |
Mnnn | RepRap-defined command, such as turn on a cooling fan |
Tnnn | Select tool nnn. In RepRap, a tool is typically associated with a nozzle, which may be fed by one or more extruders. |
Snnn | Command parameter, such as time in seconds; temperatures; voltage to send to a motor |
Pnnn | Command parameter, such as time in milliseconds; proportional (Kp) in PID Tuning |
Xnnn | A X coordinate, usually to move to. This can be an Integer or Fractional number. |
Ynnn | A Y coordinate, usually to move to. This can be an Integer or Fractional number. |
Znnn | A Z coordinate, usually to move to. This can be an Integer or Fractional number. |
U,V,W | Additional axis coordinates (RepRapFirmware) |
Innn | Parameter - X-offset in arc move; integral (Ki) in PID Tuning |
Jnnn | Parameter - Y-offset in arc move |
Dnnn | Parameter - used for diameter; derivative (Kd) in PID Tuning |
Hnnn | Parameter - used for heater number in PID Tuning |
Fnnn | Feedrate in mm per minute. (Speed of print head movement) |
Rnnn | Parameter - used for temperatures |
Qnnn | Parameter - not currently used |
Ennn | Length of extrudate. This is exactly like X, Y and Z, but for the length of filament to consume. |
Nnnn | Line number. Used to request repeat transmission in the case of communications errors. |
*nnn | Checksum. Used to check for communications errors. |
Case sensitivity
The original NIST G-code standard requires gcode interpreters to be case-insensitive, except for characters in comments. However, not all 3D printer firmwares conform to this and some recognise uppercase command letters and parameters only.
- Firmwares that are known to be case-insensitive
- RepRapFirmware version 1.19 and later (except within quoted strings)
- Firmwares that are known to be case-sensitive
- RepRapFirmware version 1.18 and earlier
Quoted strings
In RepRapFirmware, some commands support quoted strings when providing file names and other string parameters. This allows file names, WiFi passwords etc. to contain spaces, semicolons and other characters that would otherwise not be permitted. Double-quote characters are used to delimit the string, and any double-quote character within the string must be repeated.
Unfortunately, some gcode sender programs convert all characters to uppercase and don't provide any means to disable this feature. Therefore, within a quoted-string, the single-quote character is used as a flag to force the following character to lowercase. If you want to include a single quote character in the string, use two single quote characters to represent one single quote character.
Example: to add SSID MYROUTER with password ABCxyz;" 123
to the WiFi network list, use command:
M587 S"MYROUTER" P"ABCxyz;"" 123"
or if you can't send lowercase characters:
M587 S"MYROUTER" P"ABC'X'Y'Z;"" 123"

RepRapFirmware 3.1 and later allow parameter values to be computed from an expression enclosed in { }. Such an expression may include constants, values from the machine object model, operators and functions. Example:
G1 X{move.axes[0].max-5} Y{move.axes[1].min+5} F6000 ; move to 5mm short of the X and Y axis limits
See https://duet3d.dozuki.com/Wiki/GCode_Meta_Commands#Section_Use_of_expressions_within_GCode_commands for more details.
Comments
G-code comments begin at a semicolon, and end at the end of the line:
N3 T0*57 ; This is a comment N4 G92 E0*67 ; So is this N5 G28*22
Some firmwares also obey the CNC G-code standard, which is to enclose comments in round brackets. Comments of this form must start and end on the same line:
(Home some axes) G28 (here come the axes to be homed) X Y
Comments and white space will be ignored by your RepRap Printer. It's better to strip these out on the host computer before sending the G-code to your printer, as this saves bandwidth.

N123
If present, the line number should be the first field in a line. For G-code stored in files on SD cards the line number is usually omitted.
If checking is supported, the RepRap firmware expects line numbers to increase by 1 each line, and if that doesn't happen it is flagged as an error. But you can reset the count using M110
(see below).
Although supported, usage of N in Machinekit is discouraged as it serves no purpose.

Example: *71
If present, the checksum should be the last field in a line, but before a comment. For G-code stored in files on SD cards the checksum is usually omitted.
The firmware compares the checksum against a locally-computed value. If they differ, it requests a repeat transmission of the line.

Example: *37428
The 8-bit checksum provides insufficient protection against noise on the received data connection in some situations, for example where the cable from a display device runs close to an extruder cable. Therefore RepRapFirmware allows a CRC to be used in place of a checksum. If present, the CRC should be the last field in a line, but before a comment. RepRapFirmware assumes that * followed by 5 digits is a CRC, whereas * followed by 1, 2 or 3 digits is a checksum. The polynomial used is 0x1021 as for CCITT CRC16.

The RepRap firmware checks the line number and the checksum (or CRC if supported). You can leave both of these out - RepRap will still work, but it won't do checking. You have to have both or neither though. If only one appears, it produces an error.
The checksum "cs" for a G-code string "cmd" (including its line number) is computed by exor-ing the bytes in the string up to and not including the * character as follows:
int cs = 0; for(i = 0; cmd[i] != '*' && cmd[i] != NULL; i++) cs = cs ^ cmd[i]; cs &= 0xff; // Defensive programming...
and the value is appended as a decimal integer to the command after the * character.

RepRapFirmware 3.01 and later supports conditions and loops in GCode. Properties from the firmware object model (e.g. current position, current tool) can be included in controlling expressions. See https://duet3d.dozuki.com/Wiki/GCode_Meta_Commands for details.

If buffering is supported, the RepRap firmware stores some commands in a ring buffer internally for execution. This means that there is no (appreciable) delay while a command is acknowledged and the next transmitted. In turn, this means that sequences of line segments can be plotted without a dwell between one and the next. As soon as one of these buffered commands is received it is acknowledged and stored locally. If the local buffer is full, then the acknowledgment is delayed until space for storage in the buffer is available. This is how flow control is achieved.
Typically, the following moving commands are buffered: G0
-G3
and G28
-G32
. The Teacup Firmware buffers also some setting commands: G20
, G21
, G90
and G91
. All other G
, M
or T
commands are not buffered.
RepRapFirmware also implements an internal queue to ensure that certain codes (like M106) are executed in the right order and not when the last move has been added to the look-ahead queue.
When an unbuffered command is received it is stored, but it is not acknowledged to the host until the buffer is exhausted and then the command has been executed. Thus the host will pause at one of these commands until it has been done. Short pauses between these commands and any that might follow them do not affect the performance of the machine.

The RepRap firmware spec treats G0
and G1
as the same command, since it's just as efficient as not doing so.2
Most RepRap firmwares do subtle things with feedrates.
G1 F1500 ; Set feedrate to 1500mm/min G1 X50 Y25.3 E22.4 ; Move and extrude
In the above example, we first set the feedrate to 1500mm/min, then move to 50mm on X and 25.3mm on Y while extruding 22.4mm of filament between the two points.
G1 F1500 ; Feedrate 1500mm/min G1 X50 Y25.3 E22.4 F3000 ; Accelerate to 3000mm/min
However, in the above example, we set a feedrate of 1500 mm/min, then do the same move, but accelerating to 3000 mm/min. Everything stays synchronized, so extrusion accelerates right along with X and Y movement.
The RepRap spec treats the feedrate as simply another variable (like X, Y, Z, and E) to be linearly interpolated. This gives complete control over the acceleration and deceleration of the printer head in a way that ensures everything moves smoothly together and the right volume of material is extruded at all points.3
To reverse the extruder by a given amount (for example to reduce its internal pressure while it does an in-air movement so that it doesn't dribble) simply use G0
or G1
to send an E
value that is less than the currently extruded length.
- Примечания
1Some firmwares allow for the RepRap to enable or disable the "sensing" of endstops during a move. Please check with whatever firmware you are using to see if they support the H
parameter in this way, as damage may occur if you assume incorrectly. In RepRapFirmware, using the H1
or H2
parameter on a delta printer causes the XYZ
parameters to refer to the individual tower motor positions instead of the head position, and to enable endstop detection as well if the parameter is H1. H3 may be used to measure axis lengths and H4 can be used to stop when an endstop is hit while updating the position only (H4 is supported in 3.2-b4 and later).
2In the RS274NGC Spec, G0
is Rapid Move, which was used to move between the current point in space and the new point as quickly and efficiently as possible, and G1
is Controlled Move, which was used to move between the current point in space and the new point as precise as possible. In RepRapFirmware, G1 is always a linear move but G0 may not be linear (e.g. on a SCARA machine); however a G0 move will never go below the lower of the initial and final Z height of the move.
3Some firmwares may not support setting the feedrate inline with a move.
4RepRapFirmware provides an additional 'R' parameter to tell the machine to add the coordinates of the specified restore point to all axis coordinates mentioned in the G0 or G1 command. Axes that are not mentioned in the G0 or G1 command are not moved. When a print is paused, the coordinates are saved in restore point #1. When a tool change is commenced, the coordinates are saved in restore point #2. Coordinates can also be saved in restore points explicity using the G60 command.
Some older machines, CNC or otherwise, used to move faster if they did not move in a straight line. This is also true for some non-Cartesian printers, like delta or polar printers, which move easier and faster in a curve.

Perform a direct, uninterpolated, and non-kinematic synchronized move of one or more steppers directly. Units may be linear (e.g., mm or inches on DELTA
) or specified in degrees (SCARA). This command is useful for initialization, diagnostics, and calibration, and should be disabled on production equipment. This type of move can be potentially dangerous, especially for deltabots, so implementations should do their best to limit movement to prevent twerking and damaging the carriage assembly.

Remember that any parameter that you don't specify will automatically be set to the last value for that parameter. That usually means that you want explicitly to set Z0.0. RepRapFirmware will report the tool parameters if only the tool number is specified.
The precise meaning of the X, Y (and other offset) values is: with no offset this tool is at this position relative to where a tool with offset (0, 0, 0) would be. So if the tool is 10mm to the left of a zero-offset tool the X value would be -10, and so on.
The R
value is the standby temperature in oC that will be used for the tool, and the S
value is its operating temperature. If you don't want the tool to be at a different temperature when not in use, set both values the same. See the T code (select tool) below. In tools with multiple heaters the temperatures for them all are specified thus: R100.0:90.0:20.0 S185.0:200.0:150.0 .

- Примечания
1Marlin uses G10/G11 for executing a retraction/unretraction move. Smoothie uses G10
for retract and G10 Ln
for setting workspace coordinates. RepRapFirmware interprets a G10 command with no P or L parameter as a retraction command.
2It's usually a bad idea to put a non-zero Z
value in as well unless the tools are loaded and unloaded by some sort of tool changer or are on indepedent carriages. When all the tools are in the machine at once they should all be set to the same Z height.
3If the absolute zero temperature (-273.15) is passed as active and standby temperatures, RepRapFirmware will only switch off the tool heater(s) without changing their preset active or standby temperatures. RepRapFirmware-dc42 does not support this setting.
4Tool offsets are applied after any X axis mapping has been performed. Therefore if for example you map X to U in your M563
command to create the tool, you should specify a U offset not an X offset. If you map X to both X and U, you can specify both offsets. (Not supported on all firmwares).
5L1 sets the offsets of the specified tool relative to the head reference point to the specified values. L2 sets the current workplace coordinate offsets to the specified values. L20 adjusts the current workplace coordinate offsets so that the current tool head position has the specified coordinates. NOTE on some firmwares L is required (and is required by NIST standard). P is also required to specify either the tool to update or the WCS to update.

1In Marlin firmware and Derivatives Mk4duo this is implemented by hard-coded firmware behaviours As defined for variables NOZZLE_CLEAN_STROKES, NOZZLE_CLEAN_START_POINT, NOZZLE_CLEAN_END_POINT and NOZZLE_CLEAN_PARK.
With NOZZLE_CLEAN_PARK enabled, the nozzle will automatically return to the XYZ position after G12 is run.

The use of G12 for tool cleaning clashes with the established use of G12 for circular pocket milling on CNC machines. For this reason, RepRapFirmware does not support G12.

The G26
Mesh Validation Pattern is designed to be used in conjunction with various Mesh Bed Leveling systems – those that adjust for an uneven —rather than just tilted— bed. The G26
command prints a single layer pattern over the entire print bed, giving a clear indication of how accurately every mesh point is defined. G26
can be used to determine which areas of the mesh are less-than-perfect and how much to adjust each mesh point.
G26
has large feature list, including a built-in test that extrudes material onto the bed. By default this is configured for PLA temperatures and a nozzle size of 0.4mm. (This will be adjustable in an upcoming version of Marlin.)

G28 ; Home all axes (On Prusa i3 MK2/s,MK2.5/s,MK3/s it will also perform mesh bed leveling)2 G28 X Z ; Home the X and Z axes
When the firmware receives this command, it quickly moves the specified axes (or all axes if none are given) to the endstops, backs away from each endstop by a short distance, and slowly bumps the endstop again to increase positional accuracy. This process, known as "Homing", is required to determine the position of the print carriage(s). Some firmware may even forbid movement away from endstops and other operations until the axes have been homed.
The X
, Y
, and Z
parameters act only as flags. Any coordinates given are ignored. For example, G28 Z10
results in the same behavior as G28 Z
. Delta printers cannot home individual axes, but must always home all three towers, so the X Y Z
parameters are simply ignored on these machines.
Marlin firmware (version 1.1.0 and later) provides an option called Z_SAFE_HOMING
for printers that use a Z probe to home Z instead of an endstop. With this option, the XY axes are homed first, then the carriage moves to a position –usually the middle of the bed– where it can safely probe downward to home Z.
RepRapFirmware uses macro files to home either all axes or individual axes. If all axes are homed, the file homeall.g
is processed. For individual axes the homex.g
, homey.g
, or homez.g
file will be used. On Delta printers, G28
command will always home all three towers by processing the homedelta.g
file, regardless of any X
Y
Z
parameters.
Because the behavior of G28
is unspecified, it is recommended not to automatically include G28
in your ending G-code. On a Cartesian this will result in damaging the printed object. If you need to move the carriage at the completion of a print, use G0
or G1
.

parameter that tells the printer to return to the coordinates it was at before homing.
2 Original Prusa i3 MK2/s, MK2.5/s, MK3/s supports a W

This command uses a probe to measure the bed height at 3 or more points to determine its tilt and overall flatness. It then enables compensation so that the nozzle will remain parallel to the bed. The printer must be homed with G28
before using this command.
Each firmware behaves differently and depends on the type of bed leveling that's been configured. For example, Marlin 1.0.2 provides 3 different types of automatic bed leveling (probe required) and a manual bed leveling option. See your firmware's documentation for the specific options available.

G29 Auto Bed Leveling (Marlin - MK4duo)
Marlin 1.0.2 and earlier provides three options for automatic bed leveling:
- The 3-point method probes the bed at three points to produce a matrix, adjusting for a flat but tilted bed.
- The planar grid method (non-Delta) probes a grid pattern to produce a matrix by the "least-squares" method, adjusting for a flat but tilted bed.
- The bilinear grid method (Delta only) probes a grid pattern to produce a mesh, using bilinear interpolation to adjust for an uneven bed.
Marlin 1.1.0 and later allows the bilinear grid (i.e., "mesh") method to be used on all types of machines, not just deltas. This is the recommended leveling method going forward.
Also in Marlin 1.1.0 and later, the PROBE_MANUALLY
option allows all forms of Auto Bed Leveling to be used without a probe. The procedure is similar to that of MESH_BED_LEVELING
(see below). Begin the process with G29
to move the nozzle to the first point. Adjust the Z axis using G1
or your host software. Send G29
again to move to the next point and repeat until all points have been sampled.

G29 Unified Bed Leveling (Marlin - MK4duo)
Marlin firmware (version 1.1.0 and later) includes the AUTO_BED_LEVELING_UBL
option for Unified Bed Leveling. UBL combines mesh leveling, tilted plane adjustment, 3-point leveling, and manual editing tools all together in a single package. To accomplish so much, UBL overloads `G29` with several new parameters and provides an additional G26
Mesh Tuning feature.
See the MarlinFW website for a dedicated Unified Bed Leveling page and complete documentation on `G29` for UBL and `G26` Mesh Validation.

G29 Manual Bed Leveling (Marlin - MK4duo)
Marlin firmware (version 1.0.2 and later) also provides a MESH_BED_LEVELING
feature that can be used to perform bed leveling on machines lacking a probe. This form of bed leveling compensates for uneven Z height across the surface of the bed using a mesh and bilinear interpolation.

instead with firmware 0.92.8 and above.
S0
Default value. Z bed heights are calculated at the measured points, relative to current Z position before issuingG29
.S1
Same asS0
, except printer immediately moves to Z maximum position (Z max endstop required!), and calculates new Z maximum height. You must first issueG28 Z
to home to Z maximum position before issuingG29 Snnn
for this to work correctly, or the printer height will be invalid.S2
Same asS1
, except new calculated Z height is also stored to EEPROM.
G29 Mesh Bed Compensation (RepRapFirmware)
RepRapFirmware:
S0
(default if noS
parameter) Probe the bed, save the height map in a file on the SD card, and activate the height map. The default folder for the height map file is/sys
and the default file name isheightmap.csv
.S1
Load the height map from file and activate bed compensation. The default folder and filename as forS0
.S2
Clear the currently-loaded bed height map
To define the grid, see M557.
In RepRapFirmware 3.2 and later, G29 runs macro file mesh.g if it exists, otherwise it behaves like G29 S0. The mesh.g file can perform other actions (e.g. homing or tool selection) and then use G29 S0 to do the probing.

RepRapFirmware supports additional behaviour: if a Pn
field is specified the probed X

, and Z
values are saved as point n on the bed for calculating the offset plane or for performing delta printer calibration. If X
, Y
, or Z
values are specified (e.g. G30 P1 X20 Y50 Z0.3
) then those values are used instead of the machine's current coordinates. A silly Z
value (less than -9999.0) causes the machine to probe at the current point to get Z, rather than using the given value. If an S field is specified (e.g. G30 P1 Z0.3 S
) the bed plane is computed for compensation and stored. The combination of these options allows for the machine to be moved to points using G1
commands, and then probe the bed, or for the user to position the nozzle interactively and use those coordinates. The user can also record those values and place them in a setup G-code file for automatic execution.
RepRapFirmware uses the value of the S
parameter to specify what computation to perform. If the value is -1 then the Z offsets of all the points probed are printed, but no calibration is done. If the value is zero or not present, then this specifies that the number of factors to be calibrated is the same as the number of points probed. Otherwise, the value indicates the number of factors to be calibrated, which must be no greater than the number of points probed. In version 1.09, the number of factors may be 3, 4 or 5 when doing auto bed compensation on a Cartesian or CoreXY printer, and 3, 4, 6 or 7 when doing auto calibration of a Delta printer.
RepRapFirmware supports an optional H
parameter, which is a height correction for that probe point. It allows for the Z probe having a trigger height that varies with XY position. The nominal trigger height of the Z probe (e.g. at bed centre) is declared in the Z
parameter of the G31
command in the config.g file. When you probe using G30
and the probe triggers, the firmware will assume that the nozzle is at the nominal trigger height plus the value you have in the H
parameter.
1MK4duo Firmware support an optional parameter for Delta.

parameter- Примеры
G31 P500 Z2.6 G31 X16.0 Y1.5
When used on its own this reports whether the Z probe is triggered, or gives the Z probe value in some units if the probe generates height values. If combined with a Z and P field (example: G31 P312 Z0.7
) this will set the Z height to 0.7mm when the Z-probe value reaches 312 when a G28 Z0
(zero Z axis) command is sent. The machine will then move a further -0.7mm in Z to place itself at Z = 0. This allows non-contact measuring probes to approach but not touch the bed, and for the gap left to be allowed for. If the probe is a touch probe and generates a simple 0/1 off/on signal, then G31 Z0.7
will tell the RepRap machine that it is at a height of 0.7mm when the probe is triggered.
In RepRapFirmware, separate G31
parameters may be defined for different probe types (i.e. 0+4 for switches, 1+2 for IR probes and 3 for alternative sensors). To specify which probe you are setting parameters for, send a M558 command to select the probe type before sending the G31
command, or use the T
parameter.
In Repetier, G31
supports no parameters and simply prints the high/low status of the Z probe.
- Примечания
1X and Y offsets of the Z probe relative to the print head (i.e. the position when the empty tool is selected) can be specified in RepRapFirmware. This allows you to calculate your probe coordinates based on the geometry of the bed, without having to correct them for Z probe X and Y offset.
2In RepRapFirmware, additional parameters 'S' (bed temperature in oC at which the specified Z
parameter is correct, default is current bed temperature) and 'C' (temperature coefficient of Z
parameter in mm/oC, default zero) can be set for the alternative (ultrasonic) sensor. This is useful for probes that are affected by temperature such as PINDA. RepRapFirmware 3.1 and later allow both first and second order temperature coefficients to be specified, e.g. C0.015:0.001.

G32 ; Probe and calculate G32 Snnn ; Each firmware has its own parameters G32 Snnn Pnnn ; Refer to their specific documentation
This command is implemented as a more sophisticated form of bed leveling (which uses a transformation matrix or motorized correction. Smoothieware uses this code instead of `G29`.
Each firmware behaves differently. For example, Repetier firmware allows for motorized rotation of the bed whilst ReprapFirmware probes the bed with a transformation matrix.
Probe and calculate in Reprapfirmware
RepRapFirmware executes macro file bed.g
in response to the G31 command. The bed.g
file is typically used to probe the bed and then perform delta calibration if the printer is a delta, or to perform individual leadscrew adjustment to level the bed if the printer has multiple independently-controlled Z motors, or to advise the user on how much to adjust each bed levelling adjustment screw.
Probe and calculate in Repetier firmware
This command probes the bed at 3 or more pre-defined points and implements bed leveling compensation by either moving the A axis during printing (as with regular bed leveling, G29
) or by tilting the bed with motors.
- Параметры
Snnn
Bed leveling methodPnnn
Bed correction method
The values for Snnn and Pnnn are as follows:
S0
This method measures at the 3 probe points and creates a plane through these points. If you have a really planar bed this gives the optimum result. The 3 points must not be in one line and have a long distance to increase numerical stability.S1
This measures a grid. Probe point 1 is the origin and points 2 and 3 span a grid. We measure BED_LEVELING_GRID_SIZE points in each direction and compute a regression plane through all points. This gives a good overall plane if you have small bumps measuring inaccuracies.S2
Bending correcting 4 point measurement. This is for cantilevered beds that have the rotation axis not at the side but inside the bed. Here we can assume no bending on the axis and a symmetric bending to both sides of the axis. So probe points 2 and 3 build the symmetric axis and point 1 is mirrored to 1m across the axis. Using the symmetry we then remove the bending from 1 and use that as plane.P0
Use a rotation matrix. This will make z axis go up/down while moving in x/y direction to compensate the tilt. For multiple extruders make sure the height match the tilt of the bed or one will scratch. This is the default.P1
Motorized correction. This method needs a bed that is fixed on 3 points from which 2 have a motor to change the height. The positions are defined in firmware by BED_MOTOR_1_X, BED_MOTOR_1_Y, BED_MOTOR_2_X, BED_MOTOR_2_Y, BED_MOTOR_3_X, BED_MOTOR_3_Y Motor 2 and 3 are the one driven by motor driver 0 and 1. These can be extra motors like Felix Pro 1 uses them or a system with 3 z axis where motors can be controlled individually like the Sparkcube does. This method requires a Z max endstop.

G93
is Inverse Time Mode. In inverse time feed rate mode, an F
word means the move should be completed in (one divided by the F
number) minutes.
For example, F2.0
means the move should be completed in a half a minute.
When the inverse time feed rate mode is active, an F
word must appear on every line which has a G1
, G2
, or G3
motion, and an F
word on a line that does not have G1
, G2
, or G3
is ignored. Being in inverse time feed rate mode does not affect G0
(rapid move) motions.

The RepRap machine finishes any moves left in its buffer, then shuts down. All motors and heaters are turned off. It can be started again by pressing the reset button on the master microcontroller, although this step is not mandatory on RepRapFirmware. See also M1
, M112
.
The Marlin Firmware does wait for user to press a button on the LCD, or a specific time. "M0 P2000" waits 2000 milliseconds, "M0 S2" waits 2 seconds.
RepRapFirmware executes cancel.g if this file is present, if the print is paused and if the axes are homed. Otherwise stop.g is run and the drives are put into idle mode. Also the heaters are turned off if no 'H1' parameter is specified.

This code lists all files in the root folder or G-code directory of the SD card to the serial port. One name per line, like:
SQUARE.G SQCOM.G ZCARRI~2.GCO CARRIA~1.GCO
Please note that a file list response is usually encapsulated. Standard configurations of RepRapFirmware mimic this style in emulation mode:
Begin file list: SQUARE.G ZCARRI~2.GCO End file list ok
The file size may be appended as an integer representing the size in bytes:
Begin file list: SQUARE.G 1234 ZCARRI~2.GCO 234 End file list ok
At least OctoPrint also supports an additional format showing the file's long name (see also M33) after the size:
Begin file list: SQUARE.G 1234 SQUARE.G ZCARRI~2.GCO 234 ZCARRIAGE_V2.GCO End file list ok
If RepRapFirmware emulates no firmware compatibility, a typical response looks like:
G-code files: "Traffic cone.g","frog.gcode","calibration piece.g"
Note that some firmwares list file names in upper case, but - when sent to the M23
command (below) they must be in lower case. Teacup and RepRapFirmware have no such trouble and accept both. RepRapFirmware always returns long filenames in the case in which they are stored.
- Примечания
1If the S2 parameter is used on RepRapFirmware, then the file list (or as much as can be fitted in the output buffer) is returned in JSON format as a single array called "files" with each name that corresponds to a subdirectory preceded by an asterisk, and the directory is returned in variable "dir". The optional R parameter is the file number to start at, default 0. The JSON response also returns value "next" which is the number of the first file that wasn't returned, or 0 if all files were returned. The caller can enumerate all files even if there are very many by making successive M20 S2 calls with each call using R from the "next" value in the previous response, util "next" is zero.

Prior to pausing, RepRapFirmware runs macro file pause.g
. This allows the head to be moved away from the print, filament to be retracted, etc.
RepRapFirmware 1.20 and later also save the current state of the print to file /sys/resurrect.g. This is so that if the printer is turned off after pausing, the print can subsequently be resumed.

The "err" field is zero if successful, nonzero if the file was not found or an error occurred while processing it. The "size" field should always be present if the operation was successful. The presence or absence of other fields depends on whether the corresponding values could be found by reading the file. The "filament" field is an array of the filament lengths required from each spool. The size is in bytes, the times are in seconds, all other values are in mm. "printTime" is the printing time estimated by the slicer, "simulationTime" is the time measured when the print was simulated by the firmware. The fields may appear in any order, and additional fields may be present. Versions of RepRapFirmware prior to 3.4 do not provide the "fileName" field if information for a specific file was requested.
RepRapFirmware 3.4 and later also return information about thumbnail imaged embedded in the GCode file via an additional JSON field "thumbnails". A sample value for this field is:
- "thumbnails":[{"width":32,"height":32,"fmt":"qoi","offset":103,"size":2140},{"width":220,"height":220,"fmt":"qoi","offset":2384,"size":25464}]
The "fmt" field denotes the encoding of the thumbnail and is either "png" or "qoi". The "thumbnails" field is omitted entirely if there are no thumbnails embedded in the GCode file.

This command is used to return the data for an thumbnail image in a GCode file. The offset value should be either the offset of the start of data for a thumbnail as returned by the M36 command, or the value returned in the "next" field by a previous M36.1 command. The response is in JSON format. Here is a sample response:
- {fileName":"EscherLizardModified.gcode","offset":103,"data":"cW9pZgAAACA....AAAAB","next":0,err": 0}
The "fileName" and "offset" values are as given in the command. "data" is part or all of the base64-encoded thumbnail data starting at that offset. "next" is zero if there is no more data for that thumbnail, otherwise not all the thumbnail data was returned and "next" is the byte offset in the file of the rest of the thumbnail data. "err" is 0 if the command was successful, otherwise "err" is nonzero and the other fields may or may not be present.

M37 S1 enters simulation mode. All G and M codes will not be acted on, but the time they would take to execute will be calculated.
M37 S0 leaves simulation mode and prints the total time taken by simulated moves since entering simulation mode.
M37 with no S parameter prints the time taken by the simulation, from the time it was first entered using M37 S1, up to the current point (if simulation mode is still active) or the point that the simulation was ended (if simulation mode is no longer active).
M37 P"filename" enters simulation mode, prints the specified file, exits simulation mode, reports the print time, and appends it to the G-code file as a comment for later retrieval.

If your RepRap machine can eject the parts it has built off the bed, this command executes the eject cycle. This usually involves cooling the bed and then performing a sequence of movements that remove the printed parts from it. The X, Y and Z position of the machine at the end of this cycle are undefined (though they can be found out using the M114
command, q.v.).

If the RepRap machine was building a file from its own memory such as a local SD card (as opposed to a file being transmitted to it from a host computer) this goes back to the beginning of the file and runs it again. So, for example, if your RepRap is capable of ejecting parts from its build bed then you can set it printing in a loop and it will run and run. Use with caution - the only things that will stop it are:
- When you press the reset button,
- When the build material runs out (if your RepRap is set up to detect this), and
- When there's an error (such as a heater failure).

In Teacup, general purpose devices are handled like a heater, see M104.
In Marlin Firmware, pin numbers for 32-bit processors are in the form PORT * 100 + PIN. So pin P1_02 on LPC1768 can be set with M42 P102 S1
.
Marlin 1.x includes an I
parameter to permit setting "volatile" pins that Marlin is using.
Marlin 2.0.5.2 - 2.0.9.3 uses the M
parameter to set the pin mode: 0=INPUT, 1=OUTPUT, 2=INPUT_PULLUP, 3=INPUT_PULLDOWN. In Marlin 2.0.9.4 and up the T
parameter is used instead.
In RepRapFirmware, the S field may be in the range 0..1 or 0..255. The pin reference is an internal firmware reference named "digital pin", see Duet pinout. It maps on different connector pins depending the hardware. On Duet 0.6 and 0.8.5 hardware using pre-1.16 firmware, the supported pin numbers and their names on the expansion connector are:

M43
If your RepRap can detect when its material runs out, this decides the behaviour when that happens. The X and Y axes are zeroed (but not Z), and then the machine shuts all motors and heaters off except the heated bed, the temperature of which is maintained. The machine will still respond to G and M code commands in this state.

The S flag will result is a random sized, 5 pointed star, being traced (X and Y axis) between each sample. Usually a user will get worse repeat-ability numbers with S specified because the X axis and Y axis movements will add to the machine's positioning errors.

This function assumes the bed has been homed. Specifically, that a G28 command as been issued prior to invoking the M48 Z-Probe repeatability measurement function. Any information generated by a prior G29 Bed leveling command will be lost and need to be regenerated.
The number of samples will default to 10 if not specified. You can use upper or lower case letters for any of the options EXCEPT n. n must be in lower case because Marlin uses a capital N for its communication protocol and will get horribly confused if you send it a capital N.

M84
Stop the idle hold on all axis and extruder. In some cases the idle hold causes annoying noises, which can be stopped by disabling the hold. Be aware that by disabling idle hold during printing, you will get quality issues. This is recommended only in between or after printjobs.
On Marlin, Repetier and RepRapFirmware, M84
can also be used to configure or disable the idle timeout. For example, "M84 S10" will idle the stepper motors after 10 seconds of inactivity. "M84 S0" will disable idle timeout; steppers will remain powered up regardless of activity.
For Yaskawa systems M84 is not applicable due to servo motors not producing the annoying noises.

Macro filename. In RepRapFirmware 3 this must be enclosed in double-quote characters. In RepRapFirmware 2 the double-quote characters are optional.- Например
M98 Pmymacro.g M98 P"mymacro.g"
Runs the macro in the file mymacro.g. In conventional G Codes for CNC machines the P
parameter normally refers to a line number in the program itself (P2000 would run the Macro starting at line O2000, say). For RepRap, which almost always has some sort of mass storage device inbuilt, it simply refers to the name of a G-code file that is executed by the G98
call. That G-code file does not need to end with an M99
(return) as the end-of-file automatically causes a return. RepRapFirmware supports nested macro calls up to a depth of 5.
Certain machine parameters are saved at the start of the macro call and restored at the end. For RepRapFirmware these are: axis movement relative/absolute mode, extruder movement absolute/relative mode, feed rate, inches/mm setting, and whether or not volumetric extrusion is selected. This allows the macro to change these settings without affecting the subsequent behaviour of the calling file.
RepRapFirmware also allows the filename to include a path to a subdirectory. For relative paths, the default folder is /sys, but some implementations may check the /macros directory too. Absolute file paths are supported by RepRapFirmware too.

ok T:201 B:117 ok T:201 /202 B:117 /120 ok T:201 /202 B:117 /120 C:49.3 /50 ok T:201 /202 T0:110 /110 T1:23 /0 B:117 /120 C:49.3 /50 ok T0:110 /110 T1:23 /0 B:117 /120 ok T:20.2 /0.0 B:19.1 /0.0 T0:20.2 /0.0 @:0 B@:0 P:19.8 A:26.4
The parameters mean the following:
- T, T0, ..., Tn - extruder temperature. In a single extruder setup, only T will be reported. Some firmware variants will report no T0 in multi extruder setups - in that case T is to be considered the temperature of the first tool. Otherwise, T should be considered the temperature of the currently selected tool (which will be repeated in one of the Tn entries)
- B - bed temperature
- C - chamber temperature
- @ - Hotend power
- B@ - Bed power
- P - PINDAv2 actual (Prusa MK2.5/s MK3/s only)1
- A - Ambient actual (Prusa MK3/s only)1
A temperature report will usually include actual and target temperature for all available heaters, with the format being "actual/target" or - for some firmware variants - "actual /target". During a blocking heatup some firmware variants only report the temperature tuple for the heater that is currently in blocking heatup state.
Note that temperatures can be reported as integers or floats. There sadly are a lot of interpretations of how an M105 response should look like across firmware variants, making parsing them potentially tricky.

In Repetier and MK4duo you can add X0 (X1 MK4duo) to get raw values as well:

Recent versions of RepRapFirmware also report the current and target temperatures of all active heaters.

The first example turns on the default cooling fan at half speed. The second one inverts the cooling fan signal of the second fan and sets its value to 1/3 of its maximum. The third one sets the second fan to a thermostatic fan for heaters 1 and 2 (e.g. the extruder heaters in a dual-nozzle machine) such that the fan will be on when either hot end is at or above 45C.
Mandatory parameter 'S' declares the PWM value (0-255). M106 S0
turns the fan off. In some implementations like RepRapFirmware the PWM value may alternatively be specified as a real fraction: M106 S0.7
.
- Примечания
1These parameters are only available in RepRapFirmware.
2Marlin 1.0 to 1.1.6 only supports a single fan. Marlin 1.1.7 and up supports up to 3 fans.
3These parameters are only available in MK4duo.
M106 in RepRapFirmware
If an S
parameter is provided but no other parameter is present, then the speeds of the print cooling fans associated with the current tool will be set (see the F
parameter in the M563
command). If no tool is active then the speed of Fan 0 will be set. Either way, the speed is remembered so that it can be recalled using the R2
parameter (see below).
If no S
parameter is given but the R1 parameter is used, the fan speed when the print was last paused will be set. If the R2
parameter is used, then the speeds of the print cooling fans associated with the current tool will be set to the remembered value (see above).
The T
and H
parameters allow a fan to be configured to operate in thermostatic mode, for example to use one of the fan channels to control the hot end fan. In this mode the fan will be fully on when the temperature of any of the heaters listed in the H
parameter is at or above the trigger temperature set by the T
parameter, and off otherwise. Thermostatic mode can be disabled using parameter H-1.
The B
parameter sets the time for which the fan will be operated at full PWM when started from cold, to allow low fan speeds t be used. A value of 0.1 seconds is usually sufficient.
The L
parameter defines the minimum PWM value that is usable with this fan. If a lower value is commanded that is not zero, it will be rounded up to this value.
The X
parameter defines the maximum PWM value that is allowed for this fan. If a higher value is commanded, it will be rounded down to this value.
The I
parameter causes the fan output signal to be inverted if its value is greater than zero. This makes the cooling fan output suitable for feeding the PWM input of a 4-wire fan via a diode. If the parameter is present and zero, the output is not inverted. If the I
parameter is negative then in RRF 1.16 and later the fan is disabled, which frees up the pin for use as a general purpose I/O pin that can be controlled using M42
.
M106 in Teacup Firmware
Additionally to the above, Teacup Firmware uses M106
to control general devices. It supports the additional P
parameter, which is an zero-based index into the list of heaters/devices in config.h.
- Например
M106 P2 S255
Turn on device #3 at full speed/wattage.
Note: When turning on a temperature sensor equipped heater with M106
and M104
at the same time, temperature control will override the value given in M106
quickly.
Note well: The ambiguous text in the note above needs to be reworded by someone who knows the actual functioning. Below is my interpretation based on language use, not practical experience or code inspection.
Note: If M104
is (or becomes) active on a heater (or other device) with a feedback sensor it will correct any M106
initiated control output value change in the time it takes for the PID (of other feedback) loop to adjust it back to minimum error. It may not be easy to observe a change in the temperature (process value) due to this brief change in the control value

Breaks out of an M109
or M190
wait-for-temperature loop, continuing the print job. Use this command with caution! If cold extrusion prevention is enabled (see M302
) and the temperature is too low, this will start "printing" without extrusion. If cold extrusion prevention is disabled and the hot-end temperature is too low, the extruder may jam.
This command was introduced in Marlin 1.1.0. As with other emergency commands [e.g., M112
] this requires the host to leave space in the command buffer, or the command won't be executed until later.
Recent versions of Marlin introduce EMERGENCY_PARSER
, which overcomes the buffer limitation by watching the incoming serial stream. Commands M108, M112, M410, and M876 can all be intercepted by the emergency parser, so it is recommended to enable this feature.

M111 in RepRapFirmware
RepRapFirmware allows debugging to be set for each module. If the optional 'P' parameter is not specified, debugging will be enabled for all modules. For a list of modules, send M111 S1 P15
.
M111 in Repetier
Set the level of debugging information transmitted back to the host to level 6. The level is the OR of three bits:
#define DEBUG_ECHO (1<<0) #define DEBUG_INFO (1<<1) #define DEBUG_ERRORS (1<<2) #define DEBUG_DRYRUN (1<<3) // repetier-firmware #define DEBUG_COMMUNICATION (1<<4) // repetier-firmware
Thus 6 means send information and errors, but don't echo commands. (This is the RepRap default.)
For firmware that supports ethernet and web interfaces M111 S9
will turn web debug information on without changing any other debug settings, and M111 S8
will turn it off. Web debugging usually means that HTTP requests will be echoed to the USB interface, as will the responses.

Any moves in progress are immediately terminated, then RepRap shuts down. All motors and heaters are turned off. It can be started again by pressing the reset button on the master microcontroller. See also M0

.
Please note while many systems termed this an Emergency Stop, this terminology is regulated in many regions with specific requirements behind its use. Marlin 2.0.x has renamed this to Full Stop. RepRapFirmware has indicated an intention to make a similar change as well. This stop function is NOT implemented in a Category 0 or 1 stop fashion or with fail-safe hardware compliying with PLd or better. The function as implemented is a category 2 software stop with no redundancies.

Set the PWM for the currently-selected extruder. On its own this command sets RepRap to use the on-board potentiometer on the extruder controller board to set the PWM for the currently-selected extruder's stepper power. With an S field:
M113 S0.7
it causes the PWM to be set to the S
value (70% in this instance). M113 S0
turns the extruder off, until an M113
command other than M113 S0

1Most implementations don't support any parameters, but RepRapFirmware version 1.04 and later supports an optional 'P' parameter that is used to specify a tool number. If this parameter is present, then the system only waits for temperatures associated with that tool to arrive at their set values. This is useful during tool changes, to wait for the new tool to heat up without necessarily waiting for the old one to cool down fully.
Recent versions of RepRapFirmware also allow a list of the heaters to be specified using the 'H' parameter, and if the 'C' parameter is present, this will indicate that the chamber heater should be waited for.

This causes the RepRap machine to report the X, Y, Z and E coordinates in steps not mm to the host that it found when it last hit the zero stops for those axes. That is to say, when you zero X, the x coordinate of the machine when it hits the X endstop is recorded. This value should be 0, of course. But if the machine has drifted (for example by dropping steps) then it won't be. This command allows you to measure and to diagnose such problems. (E is included for completeness. It doesn't normally have an endstop.)

Teacup can control multiple heaters with independent PID controls. For the default shown at https://github.com/Traumflug/Teacup_Firmware/blob/master/config.default.h, heater 0 is the extruder (P0), and heater 1 is the bed (P1).
Teacup's PID proportional units are in pwm/255 counts per quarter C, so to convert from counts/C, you would divide by 4. Conversely, to convert from count/qC to count/C, multiply by 4. In the above example, S=8 represents a Kp=8*4=32 counts/C.

Volumetric Extrusion is a firmware mode (and an option you can set in some slicers) wherein all extrusion amounts are specified as a volume —using cubic millimeters or inches (i.e., mm3 or in3)— instead of a linear distance. This makes it possible to use the same G-code with any filament diameter.
M200
tells the firmware what the filament diameter is, and (if non-zero) to enable Volumetric Extrusion.
Send M200
without parameters to get the current Volumetric Extrusion state and filament diameters.
Note that slicer-commanded retraction amounts must also be specified in mm3 since the E axis is interpreted as a volume. However, when using Firmware Retraction (G10
/ G11
) the retractions specified by M207
are still set in linear units.

M201 X1000 Y1000 Z100 E2000
Set the acceleration that axes can do in units/s2.
The M201
command is intended to define the machine's physical limits. Slicers should use the M204
command to define accelerations for a job and leave M201
settings to the user.
RepRapFirmware specific: Multiple colon-separated E values can be provided, so that different extruders can use different accelerations. If a single E value is provided, that value is applied to all extruders. The values must be provided in mm/sec^2 even if G20 has been used to set units to inches.

Set the acceleration that axes should use for special types of move that should be done using reduced acceleration.
RepRapFirmware specific: these values are used for probing moves (because some types of Z probe can be triggered by high acceleration at the start of the move) and for moves that involve stall detection endstops (because high acceleration can bring the motor close to stalling). If a single E value is provided, that value is applied to all extruders. The values must be provided in mm/sec^2 even if G20 has been used to set units to inches.

The values specified are added to the endstop position when the axes are referenced. The same can be achieved with a G92
right after homing (G28
, G161
).
With Marlin firmware, the current values can read from the machine with a bare M206
command and be saved to EEPROM using the M500
command. (See also M290
: Babystepping)
A similar command is G10
, aligning these two is subject to discussion.
With Marlin 1.0.0 RC2 a negative value for z lifts(!) your printhead.
In builds of RepRapFirmware that support CNC workplace coordinates, using this command is equivalent to using G10 L2 P1 to set the coordinate offsets for workplace 1.

After placing the tip of the nozzle in the position you expect to be considered Z=0, issue this command to calibrate the Z axis. It will perform a z axis homing routine and calculate the distance traveled in this process. The result is stored in EEPROM as z_max_length. For using this calibration method the machine must be using a Z MAX endstop.
This procedure is usually more reliable than mechanical adjustments of a Z MIN endstop.
