Hey folks. Someone out there knows the simple answer I'm sure
I've been having good luck with Mach3 on my BlackToe 2' x 4' machine, but there is one semi-annoying (note really) issue I've been having, and that is, after setting X,Y, Z DRO's to zero at the top face and lower left corner of my work piece and starting the first G-code run, the Z axis ALWAYS does an air cut and resets the Z DRO to zero - so its doing what it thinks it should - just 1.5 inches above the work. When I again re-zero and start again, its fine, but not knowing how to avoid those first air cuts is getting to be a drag.
Any good suggestions?
cheers
Derrick
