PLEASE HELP! Prusa i3 Marlin Configuration.h PLEASE HELP!
May 06, 2018 04:31PM

I am sorry if this is a dumb question or request, but I am completely new at 3D printing and have not been able to get this thing working. I have searched everywhere and checked multiple videos and I am still having issues for over a month. I have tried different configs and have nearly broke the printer trusting that they would work. I purchased it on Amazon and have reached out to the manufacturer in regards to it, but I have not heard back.

I am now very desperate and would appreciate if someone could help me out. I don't truly understand this and I can admit to this, but please if someone could help me and offer me some guidance I would greatly appreciate it. below is the configuration.h file that came with the printer.

The model of the printer is a FLSUN Prusa i3 RepRap It was supposed to have auto bedleveling and z probing capabilities. I have connected everything on the motherboard and assembled everything, but I can't figure out the issues with the coding.


Here is the link to the Amazon Item I ordered in case I gave wrong information.

//======================== Thermal Runaway Protection =======================

* Thermal Protection protects your printer from damage and fire if a
* thermistor falls out or temperature sensors fail in any way.
* The issue: If a thermistor falls out or a temperature sensor fails,
* Marlin can no longer sense the actual temperature. Since a disconnected
* thermistor reads as a low temperature, the firmware will keep the heater on.
* If you get "Thermal Runaway" or "Heating failed" errors the
* details can be tuned in Configuration_adv.h

//============================= 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.

* 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_ENDSTOP_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 if probing seems unreliable. Heaters and/or fans - consistent with the
* options selected below - will be disabled during probing so as to minimize
* potential EM interference by quieting/silencing the source of the 'noise' (the change
* in current flowing through the wires). This is likely most useful to users of the
* BLTouch probe, but may also help those with inductive or other probe types.
//#define PROBING_HEATERS_OFF // Turn heaters off when probing

// 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 -25 // X offset: -left +right [of the nozzle]
#define Y_PROBE_OFFSET_FROM_EXTRUDER -29 // Y offset: -front +behind [the nozzle]
#define Z_PROBE_OFFSET_FROM_EXTRUDER -12.35 // Z offset: -below +above [the nozzle]

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

// Speed for the first approach when double-probing (with PROBE_DOUBLE_TOUCH)

// Speed for the "accurate" probe of each point

// Use double touch for probing

* 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.

// @section bedlevel

* 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. Currently, UBL is only checked out
* for Cartesian Printers. That said, it was primarily designed to correct
* poor quality Delta Printers. If you feel adventurous and have a Delta,
* please post an issue if something doesn't work correctly. Initially,
* you will need to set a reduced bed size so you have a rectangular area
* to test on.
* 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.

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

It appears most of the settings you need are in this


The newer FLSUN i3 comes with a Makerbase Gen. L v1.0. Makerbase MKS Gen. L V1.0 is supported by Marlin by defining the MOTHERBOARD variable as either BOARD_RAMPS_14_EFB
or better yet defining the BOARD_MKS_GEN_L if you are using Marlin v1.1.7 or newer.


So give me a ideal what you have.

Thank you for your reply.

The configuration.h file you posted is setup for

Ok! lets get some basics what version of Marlin do you want to start with Currently I stopped at Marlin 1.1.5, I have setup Marlin 1.1.8 though was having problems on my controller so reverted to 1.1.5.

I know you have 200X200X220 Print area.
I am sure your Steppers direction is inverted from my 3D Printer because the stepper locations are in opposite ends of the Z-Axis's.
Anyone having the Configuration information for this printer it would be welcomed.

I believe the version that came with it is Marlin version 1.1.2

I am trying to see about how to configure the Axis's so that it no longer tries to reach outside of its area. I'm not having too much luck. You are absolutely correct on the print area.

Thank you for your help.

Thank you so much for your reply.

I don't believe that is the one I have. Here is a link to the Zip file that was given to me with the printer. It has the full assembly document and model information as well as the files that were provided. Please let me know if this helps.

Thank you again in advance.

OK !!!
Thanks for posting what I need to help you.

Now can you explain exactly what you are having problems with and let's fix it. And if you want to upgrade to a newer version of Marlin Firmware let do that as well.

The posted Configuration.h file above is not the same as in the one in [1drv.ms]

You can't just get random firmware and hope it works - you need to understand what most things in the configuration.h file do.
X, Y & Z direction
MIN or MAX endstops
NO or NC endstops
Thermistor values
Feed rates

Don't try to get everything working in one try, break it down into smaller steps
get X and Y moving and their endstops working
then move onto the Z endstop (before you try get auto-level working)

then get the bed and hotend working

then check extrusion rate etc etc

Do things like the LCD last

The Factory sent Marlin 1.1.2 pre-programmed.
Difficult to help without knowing basics of the system configuration. And what he has already done.
He is having problems with it. Upgrading to a newer version firmware would only occur if it corrects original firmware or supplies options he requires.

I have helped many forum users successfully get their 3D Printers working correctly, including help from other forum users.

Are you here to help!

Thank you for your response. Yes the company sent me that file. I got another file last night finally from the company and they gave me a configuration.h file, and it seemed to work pretty well except it is now trying to reach out of it's boundaries. I'm not too sure how to configure or set the x, y, and z axis and what the numbers should be. I see where to do it, but nothing I've done has worked.

Here is a link to the file they sent.


Thank you again for your help.

In configuration.h, these set the limits

These are the locations of your endstops when homed, could be -negative values, as often there is a gap between home location and 0 location

#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0

This is the size of your build area

#define X_MAX_POS 200
#define Y_MAX_POS 200
#define Z_MAX_POS 220

Now trying to reach out of it's boundaries. I'm not too sure how to configure or set the x, y, and z axis and what the numbers should be.

When you at 0,0,0 what is the location of the nozzle with respect to the bed in millimeters.
If you are outsize the bed by 10mm in the X
If you are outsize the bed by 5mm in the Y

// This is the example
// This is the bed area set to print area including a negative offset for homing origin.

#define X_MIN_POS -20
#define Y_MIN_POS -5
#define Z_MIN_POS 0

#define X_MAX_POS 200
#define Y_MAX_POS 200
#define Z_MAX_POS 220
