How to Generate Fine Boring G76

The bore cycle in Creo Parametric 2.0 only seems to generate CYCLE / BORE which is G85. We need to bore, orient, back-off, and retract with G76. orient_angle and jog_dist doesn't output. Any way other than an Auxiliary Sequence all with CL STATEMENTS?

I think I found an answer myself. I created a custom cycle CYCLE/FINBOR and modified my post processor and the output looks to work.

CYCLE / FINBOR, DEPTH, 0.944882, CLEAR, 0.200000, IPM, 3.300000, DWELL,$

SECONDS, 0.100000, JOG_DIST, 0.005000

GOTO / 0.0000000000, 0.0000000000, 0.0000000000

CYCLE / OFF

and get through the post:

I was going to suggest that you might need to do some post-processor customizing, but you've found that yourself. There are a number of things that I've added over the years that could only be addressed this way (like using tool comments to build a list of tools used, etc.) It can be a frustrating experience debugging, but getting the things to work is very satisfying. Hardest part is finding documentation of the functions available.
