Stepper chips temps? [Solved]



  • There is an MCU temp in the latest firmware Machine Status. Is there any way to determine if the stepper chips are being sufficiently cooled? My MCU seems to be running around 35C. Can I interrogate any other temperatures?

    You can monitor for the high temp and over temp flags.

    If your board is actively cooled with a fan you're probably fine. It's far easier to use the MCU temp as a proxy for the driver temps since if one is working hard, the other will be as well and they are in the same working environment. MCU temp of 35c is quite cool.

    I have a blower fan pulling air across the stepper area of the back of the board. But it's fairly restricted so I was hoping to see what it's doing.

    Do any of those high or over temp flags appear in the web interface? Maybe in bright flashing yellow then red? 😉

    They can if you add their channel as a virtual heater in config.g

    M305 P101 S"DuetDriversTemp"

    Then in the DWC DuetDriversTemp will show up in the +Extra tab of the tools and heaters temp setting section. Add a checkmark for it to show up in the temp graph. It won't show the temp, because it just reports the flag, so the line won't move until there is a high temp or over temp situation, which is like 80c or something very high.

    P1001? Doesn't seem to appear in the interface anywhere.

    M305 P1001 S"DuetDriversTemp"

    Channel 1001 represents the temperature warning and overheat flags on the TMC2660, TMC2224 or other smart drivers on the Duet main board. It reads 0C when there is no warning, 100C if any driver reports over-temperature warning , and 150C if any driver reports over temperature shutdown.

    Never mind, looks like it's P101 X1001.
