Hey all, I have several svol's with hemera direct drive extruder/hotends. Two of them are having issue where the temperature is reading all over the place, I set it to 200 but the temp will bounce from 160 to 230 back to 200 etc. Will do this over a few seconds of time (the temp is not actually bouncing around that much but the reading shows that). I have tried replacing the thermistor on both printers with no luck, ideas what may be causing this?Thanks!
