| The motor current must be sufficient to prevent stalling, but too high a current can cause the TMC2XXX to shut down due to overheating. **Cooling of the TMC2XXX stepper drivers with a fan is ESSENTIAL** for reliable operation. They may be quiet, but they are certainly run hot! | The motor current must be sufficient to prevent stalling, but too high a current can cause the TMC2XXX to shut down due to overheating. **Cooling of the TMC2XXX stepper drivers with a fan is ESSENTIAL** for reliable operation.
