Beep after G32 completion



  • It started just today, I'm running 1.16 beta 10 and the steppers seem to emit a loud beep once I send any command after G32 completes. The controls are then unresponsive until I reset the board. Could it be a mathematical error following the bed correction matrix? G30 by itself runs fine. The problem seems to be tied to G32 only. I can only see one thing I changed today, and that would be the z probe offset. I actually set it to 1.89, does it support this format?

    Any advice?
    Here are my config.g and bed.g

  • @dcaron:

    G30 P3 S Z-100000 ; probe and calibrate with 4 parameters (as there is 4 points)

    This is highly suspicious - you should have S followed by a number, in this case presumably 4 since the comment suggests you want to calibrate four parameters.



  • Peridot,
    I did add 4 after the S parameter, it still doesn't work. It seems to hang on the next move (10 mm z lift). It beeps just after the 1500 ms delay. It seems like a stepper beep and then it hangs. It doesn't accept new commands or report temperatures. The web interface is still functional and a software reset brings it back to normal.



  • I fountd the culprit: the right formulation was S0 to end the calibration routine. I changed my file to the form in the Wiki:

    M561 ; clear any existing bed transform
    G30 P0 X10 Y10 Z-99999 ; define 4 points in a clockwise direction around the bed, starting near (0,0)
    G30 P1 X10 Y190 Z-99999
    G30 P2 X190 Y190 Z-99999
    G30 P3 X190 Y10 Z-99999
    G30 P4 X100 Y100 Z-99999 S0 ; finally probe bed centre, and calculate compensation
    G1 X0 Y0 F5000 ; move the head to the corner (optional)
