      Hello,

      I am having difficulties with mesh grid compensation. It seems that the reference point is not registered in Z-0. Therefore the printhead is never in the right Z-height.
      When I run mesh grid compensation I get two recurring differentiating results. The two pictures are taken 3 minutes apart. I can not figure out the issue.
      I have tried to change the BLtouch probe and look for mechanical issues.
      Any suggestions will be greatly appreciated!
      I am using a custom built Cartesian style 3D-printer with Duet Ethernet with BLtouch probe.

      Thanks in advance!

        The two recurring results is a known issue with some older firmware versions, triggered by Z-homing the printer with mesh bed compensation enabled.. Please try the 2.01beta2 release.

            Yes, movement of axes before homing them will be disabled by default. Use M564 H0 in config,g to allow it. See the whatsnew file for other changes that may affect you.
