Here I have home x or home y first, I unable to home the other axis. I can make G28, G34, G29 and retry homing of individual axis, but it doesn't work. M119 seems reporting good status avec the first homing. X triggered, Y not. I can tried to debug this, but I need help to add log in the right space for example so I can report the issue.
Roll back to your original Marlin 2.0 configuration if you messed with pins etc. Sensorless homing should be enabled, homing directions are positive for X Y and Z. Remove diag jumps. Start with X. Connect mechanical endstop to -X (left connecter where 1.29 pin) and validate that M119 status for x_max is changed when you trigger it.
So, Marlin must know the association between endstops and directions, otherwise, it is not possible to be sure if a given movement will force against the endstop or will untrigger it. You can surely implement some kind of autodetection, move an axis, for example, when homing, and just assume the triggered endstop is the MIN or the MAX of that axis.
Using the M206 G-Code Command. The M206 G-code is the first of the two commands that you can utilize to set the home offsets of your 3D printer in Marlin firmware. To specifically set the Z home offset value with the M206 G-code command, you will need to pass the Z parameter to it, along with the value that you would like the new Z offset to be.
In my case I have a laser engraver from makeblock, I wanted to update it to Arduino + Ramps 1.4, so I did. I put Marlin 1.1.9 on configured it and for the most part it worked beautifully , however when using the "home" function from lightburn or the "auto home" from the Marlin menu, I would always get "homing failed printer killed" and would have to reset in order to use the engraver.
Disable Z axis = true in the Marlin firmware configuration if you want to operate a Z axis handle during 3d printing. Disable Axis - line 228 // Disables axis when it's not being used. #define DISABLE_X false When performing axis homing and axis jogging for the first time, it is important to be ready to press the reset button or be
