Posted · UM original, easy feeder upgrade

Hello,

 

I had trouble with the feeder, and I think a lot of people will have the same problem. I needed some time to find the reason for still standing filament and I was not able to find information about this issue and how easy to fix it. The Problem was the black plastic roll which is pressing the filament towards the notched shaft. The roll was worn and pressed crooked towards the filament, in result there was not enough force to feed it. I removed this plastic roll and added a ball bearing. Works perfect for me!
