M122 Drive state

  • I did a M122 mid print and got the following:

    Driver 0: stalled
    Driver 1: stalled open-load-A open-load-B
    Driver 2: stalled open-load-B
    Driver 3: ok
    Driver 4: standstill
    Driver 5: ok
    Driver 6: stalled
    Driver 7: ok
    Driver 8: stalled
    Driver 9: standstill
    ```Is the meaning of these documented anywhere? Search a bit but could not find it on the wiki…

    They are documented in the Trinamic TMC2660 data sheet. At low speeds the status can't be relied on, except for any temperature warnings and short-to-ground indications. Even so, I am surprised at seeing both open load A and B indications on the same driver.

  • Should there be some values for "Probe change coordinates:", might be a bug in beat10-4?

    MaxReps: 15, StepErrors: 0, FreeDm: 102, MinFreeDm 60, MaxWait: 714435ms, Underruns: 0, 0

    That's an experimental feature to use the IR sensor to measure the registration when you have multiple print heads. You won't get any figures there under normal conditions.
