Rod,
Looks good. You could probably get the macro to do the touch off as well using G10 L20.

Cheers, Phill.

Phill, thanks, so if a the laser pointer X & Y offsets were 20mm and 30mm, would do something like:

G10 L20 P1 X20 Y30

so then would a G0 X0 Y0 put the torch where the pointer was?

I know there is a way, I just don't understand G code enough.

Yes, something like that. If you use P0 it will do the current co-ordinate system. Or you could move first then set it to X0 Y0.

Phill, thanks this did the trick for me nicely. After the torch moves to the crosshairs at the end of my macro, I added
G10 L20 P0 X0 Y0 and I have an instant touchoff ready to start cutting.

I might add my choice of NPN prox sensors bit again as one more died on the weekend so I could not home until I replaced it. Thats the second of 5 sensors I've replaced. I think I probably should have added current limiting resistors.

Anyway, one step closer to finishing my machine!

I think you should bite the bullet and replace them all for PNP.

Cheers, Phill.

Thats not really advice I want to hear! Anyway, now I've replaced both of the home switches so the limit switches should never be needed :S
