Wierd bridging
Hi, I'm gonna ask one more time on the English forum because on Czech I got no ansewer, so I hope that admins won't mind. I have problem with bridging on my total stock Mini+ calibrated from Prusa factory. I print with Prusament PLA, slice in PrusaSlicer a use default Prusa profiles for Mini and still my first layer on temp tower looks like this:
Sadly it doesn't matter on which temperature it's printing, it still looks like that. Yes, it's gonna somehow print over it and the bridge don't falls as you can see it on the 2 previous one, but this first layer of bridge is something horrible and it's only matter of time when it causes some problem.. What settings do I have to adjust in slicer to this not happening? I'm starting to get desperate because I feel like I tried everything. Flow, speed, thick bridges or whatever it's called. My fan is on 100% after the first layer when printing PLA. Sometimes it looks like the filament is warping up to the nozzle and not stretches between two points. I tried to burn the nozzle to get rid of old filament that might be somewhere stuck there but it didn't help. I even tried to swap the nozzle for brand new one, same behavior.. When printing really small bridges, like 1 or 2 centimeters max, it looks fine..
So I'm asking for help one more time on Prusa forum, because I don't want to bother Prusa support. Thanks for any kind of advice.
You are testing with white filament. White contains more pigment that other colours and does not behave typically.
Try the same tower with other colours, clear, natural and dark colours usually work best.
Cheerio,

To be on the safe side, dry the filament in a dehydrator or oven. In addition, you can also try to rotate the print orientation by 90 degrees.

RE: Wierd bridging
I have tried it with Prusament Lipstick Red, Orange, PolyTerra Charcoal Black and Cotton White. Every filament had the same horrible behaviour. I don't have any other colours availible at the moment.
RE: Wierd bridging
I use drybox so they shouldn't be wet, but I can try it.
