Ready Steady Eddy

Ok Both motors drive upto first switch then both back off then Slaved motor drives upto it's own switch while Master stays still then backs off.

This is the bit that bothers me. After one side has hit the home switch and the gantry has backed off, the other side now has to travel the 'backed off' distance until it reaches it's home switch. What I'm saying is, I don't think my machine is flexible enough to allow that to happen, and even if it was, do I want it to go through this stress each time it homes ?

If your gantry is square and your switches located level which they should be if square then the amount it moves is minimal.!. . Not even 1mm.

Now No disrespect meant here Eddy but your gantry won't be that stiff that it won't flex under the mechanical advantage of a ballscrew and stepper, ive seen much stronger than yours flex. If you want to test this then Just disconnect one motor and set the other going and see what happens. .

The machine nor the gantry is stressed when things are correct, it's only when the gantry is out of square and your forcing it back square are stress's put on the machine. Like I say when machine is setup square and correctly you wouldn't even see it happen it's that small a movement.!
