How Do I Remap the E0 and E1 Ports to X and Y Ports?
June 08, 2022 11:06PM
Hi All!

I have a Rumba board and I want to run 2 Nema 34s each on the Y and Z axis. I'm running marlin 2.0 and can't find whatever I need to change to make the E0 port function as a second Y axis port and the E1 port function as a second Z axis port (either some variable I need to change or just remap the pins). Any help would be awesome! I'd like to avoid needing a dual stepper motor adapter like this:[www.walmart.com], but if you think I have to then please specify one you think will work.
Thanks!

(NOTE: I already have all the drivers and power units I need, I'm not going to fry the board tongue sticking out smiley...this time, lol)

Its automatic in marlin

If you set #define EXTRUDERS 0

and set #define Y2_DRIVER_TYPE {your stepper driver type}
and #define Z2_DRIVER_TYPE {your stepper driver type}

(older marlins have setting to enable dual Y and Z, newer marlins look at what steppers drivers you enable)

Marlin will automatically use E0 and E1 for these functions.

If you want more control than that, you have to edit the boards pin.h file. ie pins_RUMBA.h
