How to turn off bridging
I am having problems with bridges over small holes up to 8mm in diameter. When printing in petg with 100% fan and 240 deg I get harp strings across the hole. Does anybody know how to turn off bridging so the printer just continues to print as if the hole wasnt there?
RE: How to turn off bridging
You can turn detection for Bridging Perimeters off but you can not do the same for bridging infill. Your only option is to set your bridging fan speed lower too. You can also up your bridge flow ratio as most default profiles have this lower (like 0.95 or even 0.85 on some of the bigger nozzles) to 'stretch' the filament out a bit as its bridging. Its why I tend to use Super Slicer if I need more control of a particular print/slice.
If you don't know where those settings are located then use the PS built in search function.

It is possible to stop extrusion of Bridging in slicer, not something I will teach here. however if you post your Zipped up Prusaslicer project .3mf, I will attempt to show you how to avoid this in the areas you want, minus this technique.
