Mesh Grid Compensation

  • Hi,

    So I've finally got my Delta finished but when I try to run Mesh Grid Compensation I get the following error:

    Error: G29: No valid grid defined for bed probing

    I have M557 in my config.g

    I'm running a Duet 0.6 on Firmware Version: 1.20 (2017-12-23)
    Web Interface Version: 1.20-RC3

    What am I missing?

  • maybe the 0.6 doesn't have enough ram to do a grid at that density try changing the S20 in the M557 line to S40 and see if that makes any difference

  • Thanks Doug that's sorted the issue, got it running at S25
