Not getting results when running PID calibration



  • It runs the test but errors our when ready to give me results. I'm new to 3D printing so any help would be grateful. Here is the log.

    14:47:45.327: echo: M206 X0.00 Y0.00 Z0.00
    14:47:45.327: echo:PID settings:

    14:54:27.893: bias: 114 d: 114 min: 194.06 max: 206.88
    14:54:27.893: Classic PID
    14:54:27.909: PID Autotune finished! Put the last Kp, Ki and Kd constants from above into Configuration.h
    14:54:28.930: Error:checksum mismatch, Last Line: 161
    14:54:28.930: Resend: 162

    Any help is appreciated.

    Hey @seronami

    So that error can be caused by a number of things but should overall be a non-issue as the printer was able to give you back the PID values to drop into your firmware.

    "14:47:45.330: echo: M301 P19.86 I1.00 D98.93" is the line you are looking for.



  • Those results is when I requested to see what PID’s is already in the firmware I thought. Wasn’t it suppose to post the results after the test was ran? Thank you for the reply



  • I tried 6 cycles and got a different error.

    I've tried 6 cycles this time and got this as an error.
