Z axis Endstop switch
-
Hi guys,
I have an issue with my Z axis, stops (possibly stalling out almost immediately) during negative movement on the homing command, also my Z axis endstop will not stop that axis from moving. If i manually depress the switch the light goes off on the board. It's plugged into the Zstop port. I'm running RR 3.2 firmware, Duet 2, Core X Y. This is a new install. Any help would be much appreciated.
Regards

Hi,
Your M558 command does not follow the documentation for firmware 3.2.
Perhaps after you correct it things will work.
And I don't think you need the G4 commands when homing Z.
I've never used G4 when homing any axis on any of my printers and things work fine.
