      TL;DR: I need help finding out how to set a XY offset for the Z probe.

      Hi all! I hope I'm posting in the right category. I have a duet 2 maestro V1 running RepRap 2.03 (Web interface V1.22.6). My problem is I have the BLTouch Z probe, and the way I have it attached it would be at X=-36, Y=-42 while the actual nozzle would be homed. I have the XY offset set properly for Homing, But I cannot figure it out with the bed leveling. no matter what I try in the bed.g file, I cannot make it start the leveling process at X36 Y42. it will always start at 0,0, causing it to miss the build plate, and the head to crash. at this point I'm stumped.
      Any help is appreciated!
      Thanks!

        The X and Y offsets of the probe from the nozzle should be set in the G31 command in config.g.

          I've been messing around in Bed.g as i already had tried that! turns out I needed to put a negative sign in front of the numbers for G31 the whole time!
          Thanks so much!
