G30 Acting strange



  • I updated to the most recent firmware.

    Firmware Name: RepRapFirmware for Duet WiFi
    Firmware Electronics: Duet WiFi 1.0
    Firmware Version: 1.19RC7 (2017-08-11)
    WiFi Server Version: 1.19beta10
    Web Interface Version: 1.19-RC1

    My Machine is a CoreXY that Homes to YMax, XMin, ZMin

    Made a few changes necessary for the new firmware (reverse y)

    If I home X & Y and then move to the middle of the bed.. and run a G30
    it doesnt just plunge and probe Z, it moves out of position.

    I have uploaded a video to help show the issue.

  • Yup. You haven't done everything according to the release notes. I know this because I did exactly the same as you. The latest firmware runs deploy probe and retract probe if those files are present. You need to delete them from .sys.



  • That worked. totally missed it in the notes.. thank you!!



  • Thanks but if I were awesome, I'd have read the release notes and not made the same mistake, which is the only reason I knew what the problem was. Anyway, glad you are sorted.
