G29 Z Leveling not going in the right direction

Hi there,


Hardware: Tronxy P802EA with MKS Gen 1.4 board

Firmware: Marin (1.1.x.zip … 1.1.8)


I'm trying to work out what is wrong with the auto levelling feature G29.



All of XYZ axis are moving in the right direction, calibrated ect

Homing G28 works well

Currently don't have a LCD screen setup because the "LCD 2004 5 button" display does not work with MKS Gen 1.4 from what i have researched, i think. Using Repetier-Server to manage the movements/commands



Link to a Video I recorded of what the G28 does on the printer

[youtu.be]



Also, is there a way to do Bed Leveling Test through G Code? Because i am unable to test this command below through the LCD display. It doesn't seem to work when I actually print something it stays at z=0 heigh (which is ~5mm from the hot bed)

define Z_PROBE_OFFSET_FROM_EXTRUDER -3

Attached is my current Configuration.h & Configuration_adv.h



Is there something i have missed or not configured properly? Or is this a bug and should I go to a different version of Marlin?

Thanks in advanced

#define Z_MIN_PROBE_ENDSTOP

If your probe is connected to the Zmin enstop pins, this line should be disabled (//).

Thanks for the reply, I have done the following:

609    //#define Z_MIN_PROBE_ENDSTOP

588   #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN //Enable this option for a probe connected to the Z Min endstop pin. (which is what I should have enabled, z end stop is currently plugged into this plug/pin)

Left this as is (otherwise it will cause an error in SanityCheck.h)

#define Z_MIN_PROBE_ENDSTOP_INVERTING true // set to true to invert the logic of the probe.

It seems to be doing the auto levelling G29 properly now

And Z probe offset is working correctly
