It's probably defined in the cad/cam program you are using for the gcode.
BINGO! Thanks for that heads-up! Changed this:
G81 X0.95 Y0.25 Z-0.075 R0.1 F10
to this
G81 X0.95 Y0.25 Z-0.075 R0.11 F10
and voila', Z stops at .11 - that mystery is solved.
BR549 Sez:
DID you notice when you set up Safez That you had 3 options to choose from.
Machine Coords
Work Coords
Incremental riseNo, I didn't notice. I set the SafeZ from the Alt6 page. All it says was something to the effect of the distance
being in the Current Coords... where might I find the options you mention?
BTW, given what was just discovered, it would appear now that any movement so "SafeZ" isn't being done?
I should have mentioned, I'm a total noob at machining AND Mach3 so thanks for using small monosyllabic words!
