I've been trying to edit the default Mastercam mill post processor to include an N number before each M6. I found this thread (https://en.industryarena.com/forum/j...l--158391.html), and while it does work it doesn't insert an N number before forced tool changes.

Can someone with a little more experienced shed some light on this? I'm using Mastercam 2020 and a Haas VF1, I've attached my post processor in case that helps.
Thanks!

Why do you need line numbers, in most cam software there is a check box that can allow you to post your line # or not.
