M122 - TMC Debugging

1.1.7 debug Get TMC Debug Info TMC2130 TMC2208

Description

Do a communication check for configured TMC drivers.

With no parameters, this command returns the current settings for all installed Trinamic TMC2130 and TMC2208 stepper motor drivers. The S[0|1] parameter enables/disables 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.

Usage

M122 [E] [S] [V] [X] [Y] [Z]

Parameters

[E]

Target E driver(s) only.

[S]

Flag to enable/disable continuous debug reporting.

[V]

Report raw register data. Refer to the datasheet to decypher.

[X]

Target X driver(s) only.

[Y]

Target Y driver(s) only.

[Z]

Target Z driver(s) only.
