Duet Wifi - Dual Z Motor Configuration
-
Attempting to get my printer to level using 2 independent Z motors.
1 x Z motor wired into drive 2
1 x Z motor wired into drive 4Only 1 motor operates. If I switch the motors between the two drives, the opposite motor will operate (but still only 1 at a time)

I also get this message in the console, but wiring seems fine visually, and as mentioned above, one motor at a time seems to work fine
-
@wharris87 It's complaining about driver 2, the Z driver. If both motors were connected to the Z output before, have you put the jumpers on the second Z output?
See option A in the wiring diagram:

Bingo, thankyou

M906 X1600 Y1600 Z1600:1600 E1600 I30 ; set motor currents (mA) and motor idle factor in per centRemove the second Z value in these entries. Each value is set per axis, not per motor. It's only for extruders where multiple entries can be defined here since each extruder motor is it's own axis.
