Hello,

I am trying to use dual extruders. I already configered the Configuration.h file and uploaded the firmware.
So far heating and temperature reading of hotend 1 and hotend 2 are working fine. Extruder 1 is working fine. However, extruder 2 is not working at all.

I changed the cables of extruder 1 and extruder 2, then extruder 2 is working, but extruder 1 isn´t (so I can confirm, that there is no problem with the motor itself).

Do I have to make any additional changes in the firmware?

Kind regards
René

Ah, nevermind, I just saw that the original board only comes with 4 4988 stepper drivers, so the one for the second extruder is missing. Have to order an additional one.

I tested it by switching the stepper driver from E1 to E2 and it works.
