Need some help thermal runaway issue
Need some help with toroubleshooting
Prusa i3mk3 is giving me a thermal runaway error and it has melted the heat shroud twice already. I have replaced 2 thermistors already and I still get the same issues after doing 5 to 10 prints. Here are some pictures of what's going on and I dont know what else to do. So I have tried running the paid calibration , and it fails immediately since thermal runaway. I am using overture p p l a default settings in prusa slicer version 2.9.5. It has been frightening fine for the last 3 to 4 months.And this just started happening about a month ago.
