I'm trying to mill a small slot approx 1/4 x 3/8" I get a error that
it cannot find an intersection. Fanuc 0MC error 33 ( A point of
intersection cannot be determined for cutter comp C. Modify the
program)

I'm not sure what size my resharp end mill will cut so I want to start with the full .125 comp and adjust from there.

I start above and Y-.2 offset a #7 drilled hole. machine works makes the Y move with comp, then does the -Z move then errors at N690.

Slot is too small to invoke comp in the hole. What do I need to fix. I would like to use CC more, but it always gives me trouble.

Thanks for any help.
