Homing Y Max & Z
-
Having trouble configuring my CoreXY machine endstops
this is my current config
it homes and moves properly but when it homes Y the Y position shows 0 but since its homing to Y Max it should show Y 280
also for my Z endstop I have it plugged into E0 endstop (Z probe) but i cant get it to trigger,

Your M574 command has X1 Y1 which means low end homing switches. Use X2 Y2 if your switches are at the upper end of each axis.

make the second M574 line to be
M574 X1 Y2 S1
