How to fix the error of not extruding plastic on a 3D printer

 

Problem:

Before, when printing, there was a common error that after printing for a while, the plastic could not be extruded. The machine runs without plastic and an error like this appears

Reason , i think that:

1. Due to plastic material

2. Due to friction between the plastic ring and the fixture, the motor rotates but the gears slip

My solution is:

Using ball bearings, printing additional rings into the plastic mold so that when extruding plastic, sliding friction will be reduced and it will be easier to extrude plastic.

Good luck for you
