Sounds interesting. But having spent about 850 € on this upgrade, it makes me angry that it doesn't work. And now I have a bit more time to spare and I determined to get it to work.
My main problem ist that the feeder for the first extruder is turning the wrong way. Instead of feeding the PLA it retracts it. What could be a possible solution? Any ideas? The stepping motor is Moons Stepping Motor 17HD6482-01N, 60612643, 16/05/06. The motor of the second feeder (for the 2nd extruder) is the same model. Do I need to change the wiring? If so wich wires need to be swapped?
Or is there a simpler solution by changing the the firmware?
