After using the puller wheel for a while it is possible that the wheel becomes worn, or damaged. This could have an effect on the extrusion results therefore it is time to change the wheel.
When should you replace the puller wheel?
The rubber wheel can be damaged by thermal and mechanical constraints:
- The filament getting stuck during the pulling/spooling process can cause a lot of friction. Look out for the puller wheel slipping (it scrapes away material).
- Excessively hot filament can degrade the polyurethane. In normal cases, the filament is cooled down enough to not degrade the polyurethane.
The wheel should be changed when visibly grooved or rough. Below is an extreme example of damage done to the puller wheel.

Replacing the Puller Wheel Guide
Note:
Please make sure that the new puller wheel lines up with the metal wheel (bearing) opposite. They should be symmetric so they can accurately grip the filament and pull.
