I was referring to lathe programs, but like you, I rarely have to edit mill part of it for Haas, if I do it's to add slash in front of M8 to avoid getting showered.
I managed to edit few things in post but it remains a puzzle in some areas due to complexity that I haven't been able to focus on in order to fully understand.
I will agree that post is the one to edit to gain permanent control over need for editing NC code but I am not as skilled in that as I am in making parts.
For instance, most post processors offered are very much on the spot for Haas, not many choices there for other brands or individual controllers.
Shop where I work has Yama Seiki lathe with C axis, this thing is weird in some ways that I haven't seen before.
When using polar mode, tool must go to the center line of the part before it machines feature, it's all in the book, no way to avoid it.
So, when I machine 8." diameter part I must execute that move few inches in front of the part to avoid crashing other tools into chuck.
I was able to edit Doosan post to produce C axis tool paths but P codes in it are in conflict with Yama which uses individual M codes to designate main, sub spindle rotation direction and stop codes as well as CW / CCW M codes for rotary tools.
This may not be so much of a challenge for you but it is for me, so I simply edit M codes instead.
I added notes that post with NC code, M3, M4 and M5 need to be edited for rotary tools and P code posts as P0 which is harmless if not deleted from NC program.
My post is now named "Yama Sucky" and it works well enough to be left alone.
If this was to be fixed correctly, one would have to follow all the particulars in user manual so that canned cycles are
defined correctly, only then would I be able to post a program for combined lathe and mill work and not have to edit anything after posting.
