I have a router with a motor on each side of the gantry (Y axis on the left and A axis on the right) and want to use 2 home switches to auto square the gantry. My question is lets say I find that my gantry is not square and I want to adjust the Y by .005 is there away I can adjust that in mach 3 to do a move instead of moving my Y axis home sensor? I was trying to use the distance off switch but any number I put in there just changes the DRO and does not actually move the axis.

You'll need to move the switches until it's square.
