New to a machine with tool offsets, trying to get this straight in my head.

I have set SETZ 0 at the top of the travel

Used the utility to set tool offsets to workpiece, tool #8 is at -3.1320
Z0 does put the tool right on the workpiece.

Problem is at the end of the cycle, the next G0 Z1 causes Z to hit the limit. Is the tool offset canceled and the machine is trying to overtravel ?

Code below:

N68 T8 M6 (#7 TAP DRILL)
N69 G43 Z .25 H8
N70 M3 M8 S1000

N72 G0 Z.25
N73 G81 X18.6299 Y-7.19 R0.1 Z-0.35 F5.0 G98
N74 X17.0055
N85 G80

N87 G0 Z1

Thanks!!
