Can I use the Z-axis stepper driver for my X-axis?



  • I just picked up a used Folgertech FT6 CoreXY printer, and I have been so impressed with my last duet wifi that I want to swap out the controller on this board too. The FT6 uses a single Z-axis motor and two separate stepper motors for the X-axis. I was wondering if I would be able to remap the z-axis output and x-axis output from the board? Normally I would just think about using the spare Stepper driver, but this particular model came with dual extruders, so I am pretty much out of stepper drivers other wise.



  • Hi,

    You should be able to that.

    Are you wanting to do that because of the dual connectors for the Z axis?

  • driver remapping is done via the M584 command.

    be aware of the command order.

    also the z steppers connectors are in series (halfs voltage).
    you could try assigning the e1 as the second x motor.



  • @fcwilt Yes, the dual connectors for the Z-Axis would be great as there are two X-axis Steppers that need to be driven in unison.
    @Veti Thanks for the heads up about the z-steppers only getting half voltage each. Do you know if that affects what I should set my esteps or Motor current too? I was just planning to run them at 70% of their rated current. As for the e1 output, I still need that for my second extruder, so it's not a great option right now unfortunately.

    it does not affect the esteps or the current.
    if they are run in parallel it would half the current but keep the voltage the same.
