Working with a Duet Wifi/Smart effector/E3D Volcano setup on my Anycubic Predator for over a year. Went to check on my printer at 20:01 and it immediately faulted out the heater when opening the web control. Got it restarted after checking the wiring to see if there was any problems, but now it doesn't hold temp as well as if the PID tune changed. The chart at the beginning of the print hours ago was more normal, but it continues sporatically. Is this a bug?
