Extrudes when filament change resumes
I notice that when my MK3s completes a filament change that it extrudes another inch or so of filament as the print head travels back to the "resume" point. I have to quickly pluck the extra filament from the nozzle to keep it from becoming part of the next layer. Is this a setting I've missed in PrusaSlicer?
Less of two weevils

This has come up a few times. The summary was that it's done to ensure the filament is flowing properly as the printing resumes. While you do have to quickly tweeze the extra bit off, you're already there since you just made the filament change, so it's the lesser of two evils. Between laying down a gap in the print or having to catch that strand or remove it after printing, a gap would be the worse result.

Nope, the firmware in the printer is designed to do that. Its NOT from the slicer at all. Many people have trouble with it. The correct procedure is to not remove the filament initially but to grab it with tweezers, ok the change and just hold it. As the extruder moves back to the print area and extrudes that extra inch or so it will come away with the tweezers.

Thanks for the info and tips.
I'll start waiting until the travel sequence to remove the changed filament. Having a longer string to pull will probably save me some burned fingers when I don't have the tweezers at the ready!
