I have a UM2+ (just bought it second hand). I haven't been able to get it to print right yet, but it was at least taking the filament and printing (just not well). Since updating to the 'Tinker-MarlinUltimaker2plus-17.10.1' and me accidentally doing a load filament while the filament was already loaded (lots of fun sounds). I am unable to put filament into the machine. I took the bondtech extruder off to examine and found that the large gear that connects to the stepper motor gear doesn't reach it unless it's pressed against the case of the printer (pictures to explain). So the extruder gear isn't turning.
Am I missing a gear?
Am I stupid, have I missed something?
Never had an ultimaker before so I do not know what it should look like.
Perhaps I lost a gear when taking the extruder apart, haven't been able to find it on the floor though.
Anyway, I'm going mad trying to fix this, please help.
Thanks.
