I had question I upgraded from v4 to v5 and decided to give the Machine Control Panel a test run over my OctoPrint setup. I would say about mid print the panel stop sending data to the printer.
When I came back to look at the print I had the error " heating disabled by safety timer" I checked the log and it simply had stop sending data. Any reason this would happen it was my first run.
I am going to test again.
I though maybe the USB was placed to sleep so I changed setting in my power profile.
