filament feeder

Hi,

The PLA filament in my UM2+ shows little ripples after material change.

How can I adjust the pressure of the UM2+ feeder?

Thanks

Little teeth marks is completely normal. Maybe post a picture so we can take a look?

But regardless, the pressure is adjusted with a hex screwdriver in the little hole next to the bowden tube entrance.

Thanks, I know now how to adjust the pressure.

But what pressure is optimal and how do reach that optimum?

The default is the middle position. Optimal pressure depends on filament and print settings. Trial and error is the path to "optimal" pressure. That said, I very, very rarely touch that setting. Basically the only time is if I'm trying to print some "weird" material like NinjaFlex.

So, are these filament irregularities - during pressure setting in middle position - 'normal'?
