M122 Output documentation

  • Hello,

    is there a documentation for the M122 output? I'm not able to find anything useful.

    In particular the drive output. I got here some ifcount and timeout values for my extruder.

    The meaning might be:

    1. standstill - might be the current stepper status
    2. read errors - for the stepper driver?
    3. write errors - for the stepper driver?
    4. ifcount - ?
    5. reads - ?
    6. timeouts ?
