    FIRMWARE_NAME: RepRapFirmware for Duet WiFi FIRMWARE_VERSION: 1.18.1 ELECTRONICS: Duet WiFi 1.0 FIRMWARE_DATE: 2017-04-09

    But the config.json says 1.17

  • Also did you see the heightmap pic? Just one row of data show up. Does not appear to be work as it carved out my PEI !

    I guess that may be an artifact of how DWC responds to the column of zeros. I'll ask chrishamm to check it out.



  • Why am I getting zeros if it is probing X11? What about the rest of the data as well?

    Your config.json file doesn't agreed with the config.g file you posted earlier. Please post your current config.g file again.

    The version number in config.json suggests to me that you created it before you upgraded the firmware.



  • Like I said they don't jive. I did the full firmware again and same thing. Ran m997 no change to config.json

  • So i was having the same issue of 0's in the first column, and only displaying part of the mesh in the mesh visualizer, I had unwittingly made my X start point value for the probe grid below my X offset and the first column was 0'd out for the 16 point grid.



  • I was 2mm inside the the offset and just for giggles changed it 27mm and shazaam! It started working! I guess you can't be close to the edge…..



  • Now to try a test print.
