I drew a part on bobcad, assigned and verified the tool path there and all looked correct. Then when I try to run it on Mach it stops and says "Nested comment found line 9". Isnt line 9 specified as N09? If so all I can see that it says is "N09 Z.1. I cant seem to get it to run from any line. Trying to simulate it on the screen before I turn on the controller.

Line nine will be the ninth line down which is probably not the N09.
What that will mean is there are 2 or more comments on the same line.
Post your code and it should be easy enough found.

Will you point it out?

(PROGRAM NAME - SHERLINE WAY COVER FRONT PLATE (SLIDING).NC)

Has a comment within a comment (nested)
Will work fine if you remove the () round the sliding
