Many many thanks, guys. I said I'd be away, didn't know I'd be on another planet with no 'net.....
Gerry, yes I hit Feedhold to stop axis movement as Mstcnc recommended, then lift the Z-axis to ease tool heating, then hit Stop. Hood, yes I'd like to know how to organise that macro regardless. I've been a VB/VBA programmer for many years, and would like to see how VB talks to Mech3.
If RunFromHere has a spindle start dialog in the purchased version, then my problem is solved right there. The demo RunFromHere works, just no dialog.
Seems an odd function to cripple out in a demo version. Is there a list of demo/purchased differences somewhere?
Again, many thanks everyone. I'll purchase this week.
