Filament grinding due to retraction (default settings)
Hi, so I have a prusa mk3 and when trying to print this https://www.thingiverse.com/thing:2811241
It fails at the rails and the nozzle clogs up. I believe this is due to my retraction settings even though they are default.
So far I've tried the default retration and 0.4 distance and 35 speed with no luck.
