config-axes-endstops.g (STOCK)

; Endstop configuration executed by config.g

M574 X2 P"xstop" S1 ; Set active low X endstop
M574 Y2 P"ystop" S1 ; Set active low Y endstop
M574 Z2 P"zstop" S1 ; Set active low Z endstop

I modified it to look like this :

; Endstop configuration executed by config.g

M574 X2 P"xstop" S1 ; Set active low X endstop
M574 Y2 P"ystop+e0stop" S1 ; Set active low Y endstop
M574 Z2 P"zstop" S1 ; Set active low Z endstop

Ok now both limit switches trigger the Y end stop ! Thank you.

Can you help me with the homing gcode ? I don't know how to modify it.

I know how to split the axes :

Hello. I installed a second Y home switch on my workbee. I use this firmware v3.3.0 ->

What can I change to have auto squaring of the Y axis using 2 motors ?

Thank you.

I followed a guide from the wiki I know I need to start with :
