Prusa Mini Extruder Jam
All,
I have a new problem with my extruder and cannot figure out the issue. Disconnected from the hotend, my extruder will still jam randomly. I can extrude and retract, extrude and retract, then all of a sudden it will lock up on an extrude. I have disassembled my extruder several times now, but still cannot find the issue. Here is a link to a video of the issue;
Any input would be appreciated.
RE: Prusa Mini Extruder Jam
Something does not look quite right, have you modified or reprinted anything?
The extruder housing should be a single colour, and the bowden connector looks like a push fit. Try returning your Mini to stock.

Your extruder blocks. Have you ever disassembled it and maybe missed something during assembly?
Maybe this video will help:

I have replaced the 3d printed parts only because the stock parts were still giving me issues. The extruder would grind/jam so I replaced with rev4 parts (or latest rev). Still issues. Finally upgraded to bondtech and issue is gone.

This is of course also a possibility. But make sure that you consider the estep values in the slicer (M92 E415):

Thanks Karl. I did add that. Since I upgraded to the dual drive extruder I haven't had extruder issues.
