@giuseprap said in Z AXES DOUBLE SETUP:
M584 X0.0 Y0.0 Z0.2:0.4 E0.3
"for selecting the 2 and 3 driver for the z axes".
M574 Z1 S1 P"io3.in"
"for selecting the microswitch z for the two motors"
You have used output zero twice, I suspect Y should be 0.1
For two motors with separate limits, you need two inputs?
This is what I have (on a Duet 6HC):
M574 Z1 S1 P"io3.in+io4.in" ; configure active-high endstop for low end on Z via pin io3.in
