In V4 I added the hidden option for the zero to be locked on a particular corner of the stock instead of locking it to a point relative to the machine table as it has been done in MeshCAM for years. Unfortunately, I made it default to the new version instead of the old version. V22 fixed this and put it back.
FWIW, the new option would make the whole process less dependent on the exact stock dimensions entered in MeshCAM at the expense of a more difficult setup on the mill.
