Filament diameter saftey first?

Hey, I have made a filament extruder. The diameter varies between 2.6 - 3.2, I need to make a spool which auto roll the filament onto it. Filament that is over 3 mm, will it get stuck in the k8200?

It probably will get stuck on ANY printer.
Most commercial filament is slightly below 3mm.
A Variation from 2.6 to 3.2mm will give you very inaccurate extrusion.
The variation should at least be min 2.9 and max 3mm.
The more precise, the better.

cheers,

Christian

Thanks.
