After using the puller wheel for a while it is possible that the wheel becomes 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:
- excessively hot filament can melt it partially
- the filament getting stuck during the pulling/spooling process can cause a lot of friction
The wheel should be changed when visibly grooved or rough.
Where to get a new puller wheel ?
