Auto Leveling not working.
September 10, 2018 03:05PM
Hi Guys,
Im new in this so please be gentle.lol
i have a cube X printer and did the upgrade to reprap. everything works great, but i cant seem to get the auto level working.
on marlin i activated the auto level process but nothing. when i use the G29 nothing happens. the printer just stays put at whatever location it may be. This being home position.
Can someone help me out? Thank you

Hey Cleme_o,
Which auto leveling did you enable? There are a few different types (Bilinear, 3-point, and linear)

I enable the Bilinear, and then try going 3 points and then linear, and nothing. im thinking i might need to update to the newest marlin. but guess i will have to start all over again with my set up..

Ok So i got it to work. Had to update the Marlin software. but not it wants to probe outside the bed area? what do i need to change in order por it to probe inside?

check it out

//============================= Z Probe Options =============================
// @section probes

// See [marlinfw.org]

* Enable this option for a probe connected to the Z Min endstop pin.

* Enable this option for a probe connected to any pin except Z-Min.
* (By default Marlin assumes the Z-Max endstop pin.)
* To use a custom Z Probe pin, set Z_MIN_PROBE_PIN below.
* - The simplest option is to use a free endstop connector.
* - Use 5V for powered (usually inductive) sensors.
* - RAMPS 1.3/1.4 boards may use the 5V, GND, and Aux4->D32 pin:
* - For simple switches connect...
* - normally-closed switches to GND and D32.
* - normally-open switches to 5V and D32.
* WARNING: Setting the wrong pin may have unexpected and potentially
* disastrous consequences. Use with caution and do your homework.

* Probe Type
* Allen Key Probes, Servo Probes, Z-Sled Probes, FIX_MOUNTED_PROBE, etc.
* Activate one of these to use Auto Bed Leveling below.

* The "Manual Probe" provides a means to do "Auto" Bed Leveling without a probe.
* Use G29 repeatedly, adjusting the Z height at each point with movement commands
* or (with LCD_BED_LEVELING) the LCD controller.
//#define MANUAL_PROBE_START_Z 0.2

* A Fix-Mounted Probe either doesn't deploy or needs manual deployment.
* (e.g., an inductive probe or a nozzle-based probe-switch.)

* Z Servo Probe, such as an endstop switch on a rotating arm.
//#define Z_PROBE_SERVO_NR 0 // Defaults to SERVO 0 connector.
//#define Z_SERVO_ANGLES {70,0} // Z Servo Deploy and Stow angles

* The BLTouch probe uses a Hall effect sensor and emulates a servo.
//#define BLTOUCH
//#define BLTOUCH_DELAY 375 // (ms) Enable and increase if needed

* Enable one or more of the following if probing seems unreliable.
* Heaters and/or fans can be disabled during probing to minimize electrical
* noise. A delay can also be added to allow noise and vibration to settle.
* These options are most useful for the BLTouch probe, but may also improve
* readings with inductive probes and piezo sensors.
//#define PROBING_HEATERS_OFF // Turn heaters off when probing
//#define WAIT_FOR_BED_HEATER // Wait for bed to heat back up between probes (to improve accuracy)
//#define PROBING_FANS_OFF // Turn fans off when probing
//#define DELAY_BEFORE_PROBING 200 // (ms) To prevent vibrations from triggering piezo sensors

// A probe that is deployed and stowed with a solenoid pin (SOL1_PIN)

// A sled-mounted probe like those designed by Charles Bell.
//#define Z_PROBE_SLED
//#define SLED_DOCKING_OFFSET 5 // The extra distance the X axis must travel to pickup the sled. 0 should be fine but you can push it further if you'd like.

// For Z_PROBE_ALLEN_KEY see the Delta example configurations.

* Z Probe to nozzle (X,Y) offset, relative to (0, 0).
* X and Y offsets must be integers.
* In the following example the X and Y offsets are both positive:
* +-- BACK ---+
* | |
* L | (+) P | R <-- probe (20,20)
* E | | I
* F | (-) N (+) | G <-- nozzle (10,10)
* T | | H
* | (-) | T
* | |
* O-- FRONT --+
* (0,0)
#define X_PROBE_OFFSET_FROM_EXTRUDER 83 // X offset: -left +right [of the nozzle]
#define Y_PROBE_OFFSET_FROM_EXTRUDER 0 // Y offset: -front +behind [the nozzle]
#define Z_PROBE_OFFSET_FROM_EXTRUDER 0 // Z offset: -below +above [the nozzle]

// Certain types of probes need to stay away from edges
#define MIN_PROBE_EDGE 10

// X and Y axis travel speed (mm/m) between probes
#define XY_PROBE_SPEED 8000

// Feedrate (mm/m) for the first approach when double-probing (MULTIPLE_PROBING == 2)

// Feedrate (mm/m) for the "accurate" probe of each point

// The number of probes to perform at each point.
// Set to 2 for a fast/slow probe, using the second probe result.
// Set to 3 or more for slow probes, averaging the results.

* Z probes require clearance when deploying, stowing, and moving between
* probe points to avoid hitting the bed and other hardware.
* Servo-mounted probes require extra space for the arm to rotate.
* Inductive probes need space to keep from triggering early.
* Use these settings to specify the distance (mm) to raise the probe (or
* lower the bed). The values set here apply over and above any (negative)
* probe Z Offset set with Z_PROBE_OFFSET_FROM_EXTRUDER, M851, or the LCD.
* Only integer values >= 1 are valid here.
* Example: `M851 Z-5` with a CLEARANCE of 4 => 9mm from bed to nozzle.
* But: `M851 Z+1` with a CLEARANCE of 2 => 2mm from bed to nozzle.
#define Z_CLEARANCE_DEPLOY_PROBE 10 // Z Clearance for Deploy/Stow
#define Z_CLEARANCE_BETWEEN_PROBES 5 // Z Clearance between probe points
#define Z_CLEARANCE_MULTI_PROBE 5 // Z Clearance between multiple probes
//#define Z_AFTER_PROBING 5 // Z position after probing is done

#define Z_PROBE_LOW_POINT -2 // Farthest distance below the trigger-point to go before stopping

// For M851 give a range for adjusting the Z probe offset

// Enable the M48 repeatability test to test probe accuracy

// For Inverting Stepper Enable Pins (Active Low) use 0, Non Inverting (Active High) use 1

#define X_MAX_POS ((X_BED_SIZE) / 2)
#define Y_MAX_POS ((Y_BED_SIZE) / 2)
#define Z_MAX_POS 230.0

* Software Endstops
* - Prevent moves outside the set machine bounds.
* - Individual axes can be disabled, if desired.
* - X and Y only apply to Cartesian robots.
* - Use 'M211' to set software endstops on/off or report current state

// Min software endstops constrain movement within minimum coordinate bounds

// Max software endstops constrain movement within maximum coordinate bounds

//#define SOFT_ENDSTOPS_MENU_ITEM // Enable/Disable software endstops from the LCD

* Filament Runout Sensors
* Mechanical or opto endstops are used to check for the presence of filament.
* RAMPS-based boards use SERVO3_PIN for the first runout sensor.
* For other boards you may need to define FIL_RUNOUT_PIN, FIL_RUNOUT2_PIN, etc.
* By default the firmware assumes HIGH=FILAMENT PRESENT.
#define NUM_RUNOUT_SENSORS 1 // Number of sensors, up to one per extruder. Define a FIL_RUNOUT#_PIN for each.
#define FIL_RUNOUT_INVERTING false // set to true to invert the logic of the sensor.
#define FIL_RUNOUT_PULLUP // Use internal pullup for filament runout pins.

//=============================== Bed Leveling ==============================
// @section calibrate

* Choose one of the options below to enable G29 Bed Leveling. The parameters
* and behavior of G29 will change depending on your selection.
* If using a Probe for Z Homing, enable Z_SAFE_HOMING also!
* Probe 3 arbitrary points on the bed (that aren't collinear)
* You specify the XY coordinates of all 3 points.
* The result is a single tilted plane. Best for a flat bed.
* Probe several points in a grid.
* You specify the rectangle and the density of sample points.
* The result is a single tilted plane. Best for a flat bed.
* Probe several points in a grid.
* You specify the rectangle and the density of sample points.
* The result is a mesh, best for large or uneven beds.
* - AUTO_BED_LEVELING_UBL (Unified Bed Leveling)
* A comprehensive bed leveling system combining the features and benefits
* of other systems. UBL also includes integrated Mesh Generation, Mesh
* Validation and Mesh Editing systems.
* Probe a grid manually
* The result is a mesh, suitable for large or uneven beds. (See BILINEAR.)
* For machines without a probe, Mesh Bed Leveling provides a method to perform
* leveling in steps so you can manually adjust the Z height at each grid-point.
* With an LCD controller the process is guided step-by-step.

* Normally G28 leaves leveling disabled on completion. Enable
* this option to have G28 restore the prior leveling state.

* Enable detailed logging of G28, G29, M48, etc.
* Turn on with the command 'M111 S32'.
* NOTE: Requires a lot of PROGMEM!

// Gradually reduce leveling correction until a set height is reached,
// at which point movement will be level to the machine's XY plane.
// The height can be set with M420 Z

// For Cartesian machines, instead of dividing moves on mesh boundaries,
// split up moves into short segments like a Delta. This follows the
// contours of the bed more closely than edge-to-edge straight moves.
#define LEVELED_SEGMENT_LENGTH 5.0 // (mm) Length of all segments (except the last one)

* Enable the G26 Mesh Validation Pattern tool.
#define MESH_TEST_NOZZLE_SIZE 0.4 // (mm) Diameter of primary nozzle.
#define MESH_TEST_LAYER_HEIGHT 0.2 // (mm) Default layer height for the G26 Mesh Validation Tool.
#define MESH_TEST_HOTEND_TEMP 205.0 // (°C) Default nozzle temperature for the G26 Mesh Validation Tool.
#define MESH_TEST_BED_TEMP 60.0 // (°C) Default bed temperature for the G26 Mesh Validation Tool.



// Set the number of grid points per dimension.

// Set the boundaries for probing (where the probe can reach).

// Probe along the Y axis, advancing X after each column
//#define PROBE_Y_FIRST


// Beyond the probed grid, continue the implied tilt?
// Default is to maintain the height of the nearest edge.

// Experimental Subdivision of the grid by Catmull-Rom method.
// Synthesizes intermediate points to produce a more detailed mesh.
// Number of subdivisions between probe points
