G32 mes leveling ? am i doing it right?



  • here is a video I speed up ( it takes 6 min to level my bed what am I doing wrong) I have used G29 on every printer I have but haven't figured out how to use it on the duet.

    questions I have are

    do I put G32 in the start Gcode? I read that the mess is stored how can I use that?

    is G32 the proper way to level my bed? is there a better way please advise.

    I read that mesh leveling this way only stores 5 points so am I doing it wrong?

  • You are having multiple P0, P1, P2, P3 so they are overwriting each other
    You should have P0 to P16 for your 17 points probe.



  • I've always thought 5 points were plenty.
    As a matter of fact and I hope I am not misquoting DC42, but I think I read where he said especially with a glass bed that probing just the 4 corners was enough.

    I have a 300mmx300mm glass bed and I use 5 and it has been perfectly adequate for me. And If I am doing it wrong I didn't know any better.
    It only take me about 30 seconds where as you have quite a wait for yours to finish.

    I probe my bed in an "M" pattern.
    Here is my gcode for what it's worth.

    [[language]]
    ; Probe the bed at 5 points

  • @Jackal:

    You are having multiple P0, P1, P2, P3 so they are overwriting each other
    You should have P0 to P16 for your 17 points probe.

    Jackal you just pointed out something I never noticed. I have conflicting points too.
    Gonna fix that right now.
    Thanks!~



  • Thanks I was wondering what that error ment.

    And this is a 760x915 plexiglass so I want to probe more points to get a good mesh.



  • ok that many points don't work i need to get G29 working
