I keep seeing tmc driver temp warnings, I have about 70 hours on this board in can mode but every print I have been seeing this warning with a 90c bed and a chamber temp of 60c. Today was the first time I have seen the warning grow further to a shutdow....the shutdown error was TMC 'extruder' reports error: GSTAT: 00000004 uv_cp=1(Undervoltage!). I have heatsinks laying around, should I place one on the copper pad? There wasnt any provided in the box that came with the board.
