Alright, I restored the original printer firmware and now everything works fine again. Thanks for the help! Can you by any chance point me to GitHub Issues on the topic? I couldn't find any :/ Then I can track the issue myself and if there's a solution coming.by corny - Firmware - Marlin
Thanks for the quick reply. Are you saying this is a bug with the Marlin PID autotune? I've reduced the PID value as you suggested, and it reduced the oscillations, but the temperature control is still terrible. it's not stable at all, and at the start of a print doesn't manage to keep the temperature, so that the printer shut's off with a thermal runway warning.by corny - Firmware - Marlin
Hi everyone, I'm new in the forum and hope I found the right place. I have an Anet A8+ 3d printer running the latest Marlin firmware release. My issue is with the hotend temperature control. If I tell the printer to heat the hotend, the temperature won't be stabilize, but instead goes into a perfect oscillation. It looks exactly like bad PID tuning, but PID autotune doesn't seem to fix this iby corny - Firmware - Marlin
