M122 - TMC Debugging

1.1.7 debug Get TMC Debug Info HAS_TRINAMIC_CONFIG

Description

Do a communication check for configured TMC drivers. Trinamic drivers that support this feature are TMC2130, TMC2160, TMC2208, TMC2209, TMC2660, TMC5130, and TMC5160.

With no parameters, this command returns the current settings for all installed and supported Trinamic stepper drivers.
Send M122 I to re-initialize drivers after a late power-on. Use S[0|1] to enable/disable continuous debugging output.

Notes

TMC_DEBUG is no longer needed in Marlin 2.0.x, but enabling it produces an extended report.

Responses of all LOW (00:00:00:00) or all HIGH (FF:FF:FF:FF) are signs of a communication problem.
See TMC Troubleshooting for further information.
