General Mach Discussion / G98 not working in canned cycle

« on: February 08, 2016, 11:52:03 AM »

Trying out some canned cycle examples in mach3 (also tried in mach4 demo) and found that the return to initial plane not happening. G98 is active and the code works correctly under other simulators. Any ideas?  Here is a sample:

N005 G54 G90 S1200 M03 T02
N010 G00 X0.5 Y0.
N015 G43 H01 Z2.0 (Establish initial plane)
N020 M08
N025 G81 X.5 Y.5 R.1 Z-.25 F3. G99 (returns to 0.1", aok)
N030 X1.75 G98 (SHOULD RETURN TO INITIAL PLANE 2.0" after cycle. MOVES TO 0.1")
N035 X3.0 G99
N040 X5.5
N045 Y3.5
N050 X4.25
N055 X3.
N060 X.5 G98
N065 X3. Y2.
N070 G80 M09
N075 G49 G91 G28 Z0 M19
N080 M30

Thanks!
