Problem: 0.9.29 dual extruder, second extruder stuck and hangs firmware
I added a second extruder to my working configuration RAMPS 1.4 with RDD fan extender.
Fans work, heater on both extruders as well.
First extruder correctly extracts/retracs.
Second extruder get's stuck when sending extract/retract GCODE to it. The motor makes once tock, then it's locked. After a while it makes another tock sound but does not move.
I switched the motors and stepper drivers. Same problem. Also switched the "Extruder Stepper" settings, same problem but on other motor.
Just to verify my hardware, I installed Marlin. Both motors work as expected.
Is this a known problem or do I need to make more changes than simply adding a second extruder in the configuration tool?
Thanks for your help and best regards
