Mesh grid skipping first line



  • running my meshlevel macro

    G90 ; Absolute coordinates
    M557 X0:240 Y0:220 S20 ; Bed probe from and to
    M401 ; Lower BLTouch probe
    G29 S2 ; Clears bed height map in RepRapFirmware
    G29 ; Kicks off the Z probing across the height map
    M402 ; Retract BLTouch probe

    Returns this, and skips the first layer of probe points on the Y0

  • What does your G31 command look like for your probe? What is the X Y offset?

    The probe can't reach Y0. You'll have to adjust your grid values to take into account the offset.
