i have the homing set up , i think, but after reading a thread here about auto squaring the gantry i think it still needs tweeking. i think the ''X'' and ''A'' slaved are homing together and backing off together. . i thought that when ''X'' home is triggered it backs off and then ''A'' home sets itself the same way?

Yes and no.!! They both move together and which ever axis comes across a swithc first it then stops and backs off and the other keeps going and does the same.
When you have the switches set exactly together then it's seemless and you'll struggle to see this happen. If you want to see it happen then move switches further apart. Beware thou it will twist gantry so it's a good idea to remove motors or drive to ballscrews etc to see it happen.

Limit overide is here.
