Anyone point me towards how to first activate the second extruder port on the original ultimaker and then force either cura or the ultimaker itself to use that as default ? atleast until i can work out whats gone wrong with the extruder 1 port and move back to that

    Heater, sensor or feeder?

    Heater and sensor: You have to edit pins.h in Marlin and recompile it.

    Feeder: exchange the stepper driver

    I'm having the same problem on my UMO + as well. I want to try running the feeder stepper motor off of the extruder 2 port. I'm assuming I'll have to edit something in the firmware or machine settings right?
