What determines the Z-zero point
-
Hi guys,
I have a Tronxy X5S which I have fitted a Duet Wifi and a custom made extruder. The Duet is using independent drives for the two Z-motors and I have setup a macro for the leadscrews compensation using the Escher IR-probe that works nicely. The old Z-home sensor is used as before connected to the Z-endstop sensor input.Now, the question is, what of these determines the actual Z-zero position? Is it the Z-endstop homing sensor or is it the leadscrew compensation bed probe operation?

Both homing and leadscrew adjustment set the Z=0 position, so whichever happens latest will be the one that matters. For example, if you have a G28 homig command in your slicer start GCode, that homing operation will reset the Z=0 position.
