Hey folks, I'm hoping you can help.
Currently I'm putting together a laser cutter using Openbuilds ACRO system, running Ramps 1.4 and Marlin. My problem is this.
I need to run 2 Y-axis stepper motors (1.68a), but obviously there's only space for 1 to be connected (I tried wiring in series and parallel but get stutter movement, and yeah did check the drivers).
What I'd like to do is put one of the motors on the Y pins, and the other on E1 or E0. Or since I don't have a need for Z, use the dual Z pins.
Can someone show me the code I need to edit to make this happen? Any help would be greatly appreciated.

Assuming you use the Marlin from github, I would modify that file : [github.com]

By exchanging the values for all of the 4 Z_SOMETHING_PIN for the relevant Y_SOMETHING_PIN you should have swapped Z and Y axis.


I'm a programmer, but this is untested, just a theory !

Most of my technical comments should be correct, but is THIS one ?
Anyway, as a rule of thumb, always double check what people write.

It's turning into one of those days. Turns out it WAS a dodgy driver. So for the sake of simplicity, I'll stick with my current wiring setup.

However, thanks for the theory. May give it a whirl for funsies once I'm done.
