Strange behaviour, leftovers of filament on the bed
Hello,
I’m happy user of Prusa i3MK3s, I assembled it from the kit. First prints was fine but now printer is leaving long straps of plastic on the bed. Printed model itself is fine but I’m wondering from where is coming this plastic.
Nozzle is perfectly clean, also I tried PET and PLA with different temperatures and issue remains the same.
Maybe somebody knows what could be the issue. Sorry for bad picture but I don’t have my printer in my place so I took screenshot from camera.
Regards,
Wojciech

I get them also - about one per print. I think these are purge-lettes - for lack of a word for them. Print starts with a wipe, then skirt and your print, then head parks. Some time during cooldown it poops out one of these.

Thanks for giving me an idea but I found out that was different issue. Before those hairs became an issue I was repairing blocked extruder. After i reasembled it i didn't screw the nozzle hard enough so plastic was pushed between heatblock and the nozzle. After some time big blob grew on the heat block. 🙂 Not it is fixed.
