Bad case of noobism HELP!!



  • Trying to setup multiple point for mesh bed leveling and I errors from something like not clockwise direction to the latest G32
    Bed calibration error: 2 points provided but only 3, 4 and 5 supported. here is where I am at now. I tried changing the T values to numerical order ect. nothing works yet. I don't think my forehead can take much more pounding on the desk! Here is my BED.G file;

    You are better off using mesh bed leveling:

    https://duet3d.com/wiki/Using_mesh_bed_compensation

    Use M557 to define the grid and then G29 to probe it.



  • Tried doing that would not save to the bed.g file or does it need to? I deleted and remade the folder then ran it again then M500 still not saving I must be missing something…...or not?

    When you run G29 S0 or just G29, it will either fail and report an error on the Gcode Console, or succeed and create the heightmap.csv file in /sys on the SD card. You can see what is in the file by going to Settings->System Editor in the web interface, or view it graphically.



  • Im curious how to view the height map graphically. I have the heightmap.cvs.

    Thanks

    Assuming you are using DuetWebControl 1.15a or 1.15b, right click on the arrow next to the Auto Bed Compensation or Auto Delta Calibration button on the Control page, then you get a drop-down menu that includes an option for viewing the height map.



  • Thanks, I didnt have the newest WebControl.
