Title: programmable positions
Post by: johnnydoughey on June 22, 2009, 10:25:28 PM

I've been using Mach3 for some time now and have yet to discover an easy way to get back to 0,0,0 ( or predetermined location) after going to another location.  So far, I just use the keys and start tapping  as light as I can until I get it close to the marks.  Is there a button or input area which will allow me to do this easier, without resorting to proximity switches?

Thanks much

Go to zero will take you to the work coordinates zero. You have I think 256 fixture offsets. G54, G55, G56, ect. You can also go to the zero position by calling it from the mdi line or G-code. G0 G54 would be a rapid to g54. I would raise the z first though in my code if it is needed though.

G0 Z 1.0
G0 G54

This would raise your z to 1 and then go to g54.
G0 Z1.0 X0 Y0 would work too. You have a go to zero button on the default mach mill screen, program run page. You could also hardwire in a switch to do the same.
