Sorry, I did not mean to imply that I was using the Bondtech extruder. I have not taken it out of the box yet, and will wait until I can figure out what the problem with SpreadCycle is. So at the moment I have a MacEwen3D aluminium extruder which is not a geared extruder.
I'm sure the problem must be something in the firmware, but I'm not very good with software, so any suggestions are welcome.
I will try to make a video, so you can see and hear what happens when I try to extrude in SpreadCycle mode.
