4 screw leveling problem



  • I’m currently running 2.0 RC5 and I’m getting an error message when I try to level the print bed. The GCode used for leveling is:

    G30 P0 X30 Y280 Z-99999 ; probe near back left lead screw
    G30 P1 X390 Y280 Z-99999
    G30 P2 X390 Y25 Z-99999
    G30 P3 X30 Y25 Z-99999 S4 ; probe near a leadscrew and calibrate 2 motors

    This results in the following output:

    Error: Number of calibration factors (0) not equal to number of lead screws (4)
    Error: Number of calibration factors (0) not equal to number of lead screws (4)
    Lead screws adjustment made (etc.etc)
    Error: Number of calibration factors (0) not equal to number of lead screws (4)
    Error: Number of calibration factors (0) not equal to number of lead screws (4)

    Any ideas on what may be causing this?



  • Problem resolved but I don’t know exactly what it was. I have two identical printers and only one of them was exhibiting the problem. After copying all the scripts from the working printer to the other, the issue is gone. Obviously something got changed in one of the files.

    It looks like the S4 on the final G30 command wasn't being seen - possibly due to a non-printable character somewhere in that line.
