feeder gear slippage along the shaft um2+

Recommended Posts

The small nylon gear on the stepper motor shaft keeps slipping along the shaft with time and usage. Eventually it slips far enough that the gears don't mesh with each other, and the feeder stops feeding filament.

I can easilly repair this problem by disassembling the back portion of the feeder, pulling the gear back into position, and reassembling. I've had to repair this 3 times in the last year, and the printer doesn't get heavily used.

Please see attached photos: 1st the gear too far back along the shaft as to not engage, 2nd in the correct position.

Is there a solution to this problem?

Thanks, have also thought of the super glue, but would rather have an engineered solution, like a screw-attached spacer. Even just an extra nylon gear as spacer would help.

 

There was also an interesting post about contacting your dealer for a replacement nylon gear, as the gear has been improved. Mine was an early upgrade kit for Ultimaker 2 to Ultimaker 2+ just after they came out. I think I will try that route, through my contact at Ultimaker.
