Filament is stuck in printer head, I can’t get it to retreat or extrude, I have the heater on at 200c. won’t budge. I have a sovol SV01 pro.
It sounds like you have a clog. They are a lot of different ways to handle this and you can google them by search “clear 3D clog filament”.
What works best for me is set the temperature 10 to 15 degree higher than usual and quickly push the filament by hand through the hot end and then pull it out right away.
I hope it helps
