Tool board remote heater auto tune not implemented



  • Hi,
    I am in the process of setting up my printer with a tool board. The hot end is working but faults out....so I tried to do a tuning.

    M303 H0 S200 D360
    Error: M303: remote heater auto tune not implemented

    Not really sure how to get past this. When I turn the heater on it does heat up for a few seconds....and then goes to fault.

    Here is my current config. While I am at it I am also getting this error in my console which I cannot figure out " M350: Driver 2 does not support x0 microstepping
    Driver 3 does not support x0 microstepping
    Driver 4 does not support x0 microstepping
    Driver 5 does not support x0 microstepping"

    As it says, PID tuning on a tool board is not yet implemented. To work around it, you can connect the heater and sensor to the main board, do the tuning there, and then copy the parameters over.



  • @Phaedrux I missed that. Thanks


  • administrators

    Alternatively, follow the manual tuning instructions.



  • Will that be built in at some point?

    @bernie-mix
    Yes, the first step was updating the tuning algorithm, which is part of 3.2. Next step would be tuning remote heaters.



  • @Phaedrux Is that slated for 3.3 beta?


  • Moderator

    @ctilley79 I don't think it's in the 3.3 that is currently available for testing, but it's planned to be there eventually.
