32bit board with LPC1768, support marlin2.0 and smoothieware, support lcd2004/12864, On-board TMC2130 SPI interface and TMC2208 UART interface no additional wiring is required
Had a scary issue on one of my printers recently and not sure if this is an SKR issue, Marlin, or something else entirely.
During a print I suddenly noticed smoke pouring out of my hemera hotend. After a few seconds of panic I hit the power switch on the unit and waited a few minutes. When I powered the unit back on the temp that was being reported was above the set temp for the print I was doing. My theory is that the SKR / Marlin got stuck with temp values for the hotend and bed and as a result the hotend stayed in the on position and continued to apply heat.
The Octopi graphing captured the event and I have annotated it below. Note how whatever affected the hotend temp sensor also affected the bed sensor at the exact same moment.
I'm running an SKR 1.3 Running Marlin 2.0.9.1 that I update fairly regularly. The board has put out hundreds of prints at this point. I have also printed with it 3 times since the event without issue.

Happy to provide any other details.
