Yep. haven't done any multi axis for a while but I would always post it out and see where it "wants" to start and then give it a nudge in the right direction....

Try posting the feed rate on it's own line: pbld, n$, *scclgcode, *ng70s, *ng70e, e$ pbld, n$, pffr, e$ The buffer is handling the gcode and the start and finish line numbers. Looks like there are some flags set up to determine the "canned turning cycle type". Find lathecc to see list of flags.

As So not a Guru said Lathes are a bit different. Not my forte either... There is a pffr post block which forces feed output, and I can see that in the g71-73 output post blocks. However you are trying to set the feed rate in what is essentially the subroutine call line N4 G71 P5 Q12 U-0.01 W0.005 D0.08 F0.01 N5 G00 X4.5 N6 G01 X3. R.25 F.005 N7 Z-1.75 R.5 N8 X1.5 R.125 N9 Z-2.25 R.125 N10 X.75 R.125 N11 Z-3. N12 X0.73 N13 G70 P5 Q12 N13 in the above code I found this in the pread_g70 postblock: pbld, n$, *scclgcode, *ng70s, *ng70e, e$ You could try pbld, n$, *scclgcode, *ng70s, *ng70e, pffr, e$ but that will only output the current modal feed rate. So you might need to save the finish feed as a user defined variable and call it here. Running a trace in the debugger should show you what's happening more clearly.

First thing I do when surfacing is to see how the surfaces "untrim". This will usually fill any holes (there is also a separate function to fill holes). The toolpath can then be controlled by by containment , or partial retrimming. Untrimmed surfaces are easier to manipulate. Often they won't appear to change much (usually the color will change) but it will allow you to extend the surface edge to allow your cutter to "run off" the part surface but still be supported by the extended surface to avoid gouging.

There have been a number of posts that might be of interest to you. Try searching. YoDoug has posted a bunch of very nice "Okuma speak" macros, he is in the Members directory.

I think contacting Postability would be a good first option. Even without maintenance Dave is pretty keen on customer service. I don't know it for a fact but I suspect he sees any Postability product not working properly as bad for his rep. The fact that he and his team are some of the go to guys for complex posts, I think, shows it works well for him.

How old is the Postability post? Looks like you have a conflict between coolant and X coolant. It is posting out the "On" rather than command M08. I see this usually when I am selecting a different than default post which doesn't have X coolant set up, but the MD/CD does...or vice versa. Run it through the debugger.

Have you tried running the prog in MC verify using the endmill. Save it as an .stl and display it over the ballnose stock model? You will have to go to wireframe to see the undercut. I use a green solid (stock model) and red .stl for easy visual.

Material? Cutter size? I am assuming it is smaller than .2 and I normally reduce chip load 30% slotting so that's a hefty chip load for that size cutter... If time is important and you can afford it I kinda like Ron's idea. Extra endmill but you could keep the size of your finisher larger and will probably be quickest.

Analyze chain gives an overlapping chain repair option. I think there is another somewhere.....chook / nethook?

+1000 and then you have ready made text to update your header....

Actually Colin and I ended up taking a different route to achieve my requirements, although we did use the functions listed. I ended up launching my tool list using a modified .pst and .set to launch reports via the right click ops menu. It was the best option for my company, but not the only option. Do the basic Mill course on his You Tube channel and you will be in a better position to follow this mod. Get the MP documentation, without that you will almost certainly struggle.

Your Post, judging by the header has been, heavily edited. As you can see the Comments for Manual Entry As Code is controlled by gcode$ = 1006. pcomment2 #Comment from manual entry #1005 - As Comment #1006 - As Code #1007 - As Comment with output line, change at point #1026 - As Code with output line, change at point #1008 - Operation comment Try searching for if gcode$ = 1006 Probably not the best situation to learn Post Editing as you will be learning whatever bad practices may or may not be lurking in this post.... Download a copy of MPmaster and work your way through Colin's online course, then come back to this problem....

Often if the solid is "off" in a number of planes 3D transform will give a better result.

We had a problem installing programs "out of sequence". In our case we had installed X9 and 2020. Needed 2019 to do updates but it wouldn't play. In the end we uninstalled 2020, then installed 2019 then reinstalled 2020. Everything was fine then....all versions.

Need more info. You say it is an existing file, what version of mastercam was it generated in? Is it a proven program and now you have suddenly found this problem? A Zip2Go would help...

What about a program template with a contour op and your tool. Import/ merge new geometry, Open the geometry box and select the new geometry. You could use your levels to help organize if you have "families" of parts which could reside in the same program..

Only use clearance at start and end of toolpath. Its up nestled under Clearance. Will go to Retract height except enter and exit (to clearance). Mind the Absolute/ Incremental settings...

You will have to be more specific about your table. Is it just a normal slotted table or does it have a sub plate? If sub plate does it have holes.....what type....?

If you have problems, Mikron Cross Pilots might do the trick. 170 degree point so good for sheet. Not cheap but we normally get a couple of hundred holes drilling on a 30 degree slope in Inconel (not sheet).

Have you got y axis?

This will require some fairly straight forward post modification. Will need to know your base post and what you want it to look like.

1 Analyze entity 2 Analyze entity 3 Analyze distance

A good start would be to put your post in the Post Processer Development Forum. I think you could handle this with "ppost" but I will defer to Mr. Gilchrist who has more experience with this "function".
