RE: Tmc driver overtemp

1. You are on firmware 3.7.1 - That's good. 3.7.0 could cause this issue due to its heater bed switching frequency overheating the MOSFET near one of the TMC 2130's. We can rule this out based on your firmware version.

2. Older machine that was previously ok. What is causing rise in thermal stress?

  • Increased friction on in bearings/rods. DISCONNECT belts and feel each axis for any friction. Should be nearly friction with belts disconnected.
  • Dust accumulation reducing EINSY airflow
  • New enclosure and/or summer heat increasing ambient temp
