@nhof said in Is the M584 command's writing sequence important?: @army61 That is correct. So you would need M584 X0 Z1 Y2 En ; E can be 3 or 4 X motor would be plugged into the 'x' labeled output Z motor would be plugged into the 'y' labeled output Y motors would both be plugged into the 'z' labeled output If you don't get enough power from the single Y output for both motors, you can use the extra extruder driver for the other Y instead, something like so: M584 X0 Y1:4 Z2 E3 In this case the other Y motor would be plugged into 'E1' and the extruder 'E0', the rest of xyz would be standard mappings and match the labels. It's fairly important to explicitly map each driver to an axis if not using the stock settings. Thank You!
