Going back a little here to homing but was looking thru Mach manual today and noticed this in the Homing/limits section.

"When a Reference operation is performed, then the axes will run together until the final part of referencing, which
is moving just off the Home switches. Here they will move so that each stops the same distance off its
own switch. Referencing will therefore correct any racking (i.e. out of squareness) of the gantry, which
might have occurred when the machine was switched off or because of lost steps."

So they do a mixture of both really has they are slaved upto point it's backing OFF the Switch.!! Tonight Just checked on machine that is using PLCM-E3 and it works just like this. . . . . . Just thought this might clear any confussion.
