Don't uses home switches here as I have found no need for them.
That said, I assumed that axis velocity for G28.1 would be limited by the slowest axis, BUT, as defined
in the manual the G28.1 "move at current federate, as defined by Configuration".
I ASSuME that configuration means the value in motor tuning.
I guess someone with switches will need to reply about the G281.1.
You may want to say what Mach version your using.
