Feeder motor stuck.

Hello!

As the title suggests I'm having some trouble with the feeder motor (or whatever it's called).

Whenever you try to print something or change the material, the little motor that feeds the fillament into the tube becomes spastic and starts going reverse for a split second. This also causes some of the plastic to go in reverse.

The motor then starts spinning like normal and starts pushing the material back into the machine.

This is when the motor jerks back again and the process is repeated.

Here's a video of what happnes:

 

How do I fix this?

I've also noted a strange smell coming from the printer. Could this be the plastic that is stuck in the nozzle getting burnt?

Is there a blockage at your nozzle-area?

If you want to test, this could be a suggestion to give a try.

The feeder motor skipping like that is normal when there is to much pressure buildup, the motor it's self is fine but this means you have a problem somewhere else. This can be from a filament tangle, warn PTFE coupler or a blocked nozzle. You also can experience this when your temp is set to low for the print speed or even if you have leveled the glass to close to the nozzle.

Do the Atomic pull first as SandervG states as a blocked nozzle is the most likely cause.

When I try to reverse the plastic it doesn't wind back. Does that mean that it's stuck in the nozzle?

It maybe jammed inside the PTFE coupler. Heat the nozzle and try to reverse it and pull on it at the same time.

Tried it and it snapped.

There is still filament going to the nozzle.

Ok, first heat up your nozzle.

Then you can remove the blue horse shoe from underneath the white clip at your feeder.

If you have done so, push down the white clip and pull out the bowden tube.

You should be able to grab the remaining filament and pull it out.

Good luck!
