So after that bit of RTFM, here's how I would set up the homing switches;

Assuming 2 home switches used on X

1. One switch can be mounted in a fixed position while the other switch needs to be + and - adjustable in the X direction.
2. Using some form of measuring equipment e.g. large T square, set both switches square to the X axis.
3. Carry out a homing operation of the machine then using the same measuring apparatus as in step 2. check squareness of the gantry to X axis
4. If the gantry is not square then move the adjustable home switch by the required amount and in the required direction.
5. Repeat steps 3 and 4 until the gantry is square to the X axis.

Eddy Spot on, simples, can't just remember if the slave needs to be the adjustable one. I drilled some holes down the x and y then put dowels in then the square against the dowels. then readjusted the switch and tried again. ..Clive
