      Hello
      Im using my Workbee CNC to isolation mill some PCB. And i want to be able to use the mesh bed leveling to be able to cut 0.05 depth into the copper.

      Im using v style engraving bits and they have different cut width dependent on the depth of the cut.

      Im able to get mesh bed leveling to work like this:
      Navigate over to my PCB. I set the right work coordinates for x,y,z.
      Then i add the probe: M558 P4 C2 I1 H0.5 F60
      The probe map that i need to make need to be set in machine cordinates. like this: M557 X130:170 Y126:166 S3
      Then i run a G30 to reset the Z height for the machine cordinates.

      Then i run the; G29 to run the map.

      After all this is done i run the job from work cordinates. But i think the mesh bed leveling is offsetting the unused machine cordinates, and not the work coordinates.

      Anyone have any tips on how to get this to work?

        Please try firmware 2.03RC3 and se whether this is still a problem.
