thanks hood. I'll try the latest V first as I could do with the apparantly fixed CV (as of the 5th this month). Though I just checked the revision list and there's no mention of it so we'll see) Hopefully the limits will work as well.

OK I've upgraded to R2.45 and all seems well. This time it didn't trash all the settings apart from G28 in home/limits. Strange I did a diff on the original and new xml and they were identical - G28 must be stored somewhere else I guess. Limits work and I've got the homing set to Z then XY simultaneously. code is: rem out all but DoButton(24) followed by RefCombination(3). Just need to have a look at the CV improvements.

Many thanks to B and H (sounds like a cigarette  )

Np, Happy to hear that you have it working the way you wanted

Thanks
Brian
