Idler screws tightness

How tight should the idler screws on my mimi be set? I can’t see any suggestions in the manual.

I guess, nobody knows :slight_smile:

Tight enough to prevent slippage, not so tight as to grind teeth into the filament or generate lots of filament dust. Different filament types may require different settings. Some prints (with lots of retractions) will be more sensitive to the setting than other prints.

There is no one right answer. I’d suggest starting on the loose side and working your way toward the tight side. When the tension isn’t right, you can usually tell.

Thanks, this is basically what I have been doing :slight_smile:

Which toolhead? Some have jigs that set the screw distance. But in general, what b-morgan stated is the general guidance.
