Sending command to move Z moves X axis, (X commands also move X)
-
Hi there,
I have a Cartesian set up, with dual motors on the X and also dual motors on Z. Single Y, single extruder.As the title says, every command that is sent to move the Z axis instead causes the X axis to move. Right now I can't get the Z to move at all. Commands to move X or Y do so normally.
I'll post my config below, but I'm very flabbergasted. I've triple checked that my physical connections match where my M584 command maps them to. (M584 X0.0:0.1 Y0.2 Z0.3:0.4 E0.5)
Things were working well(ish) before I switched the X motors from running off a single driver with spliced wires.
Only thing I can think of is that I am only using one end stop for the dual X motors, could that roll over and cause this sort of problem?

@codyc firmware version? Are you using the Duet 3 with SBC or standalone? Early RRF 3 versions needed the M584 command splitting onto separate lines where multiple motors were defined on multiple axes, eg
M584 X0.0:0.1 Y0.2 M584 Z0.3:0.4 E0.5 ; set drive mappingSo you could try that.

Ah, still on an earlier version. I'll give that a shot right now. Duet 3 with SBC.

And that made it work. Thanks for sharing your knowledge @droftarts !
