REF ALL HOME - on start-up MACH3

[skartalov]

I do not use limit switches, but only HOME REFERENCE switches on all axis and SOFTWARE LIMITS in MACH3, that is why is vital to REF ALL HOME, everytime when I start MACH3.
Is any way to FORCE the user to do so on start-up?

Because otherwise it will happen to mechanical jam for sure!!!

You could probably make up a new screenset that has the Ref all button on the first page,  you could then have a button that would take you to the rest of the pages but only if the referenced LEDs are green.

Add G28.1 X0 Y0 Z0 to your initialization string, and uncheck the box to use it on all resets. You might also have to remove the default G80 that's in there.

This will home the machine when you click reset the first time after starting Mach.

Regarding the G28.1 you *might* want to write it as

G28.1Z0
G28.1Z0Y0

That way it will retract the Z up to zero *before* trying to move the X & Y axes.
