pocketNC 5 axis post processor errors

[cbose]

Hello Forum,

Beginner Mastercam user here.

I am currently trying to make a 5 axis toolpath in Mastercam using a 3 axis 3d high speed dynamic Opti-rough operation, then converting it to a 5 axis program using the convert to 5 axis tool. Both the 3 axis and 5 axis toolpaths generate and look fine when I simulate them, and I am able to post the 3 axis program. Problems start to arise when I go to post the 5 axis program. When I post, the post processor will run for a couple of minutes, making seemingly little progress, and then an window pops up saying "MACHINE LIMITS REACHED. ROTARY WILL UNWIND". It makes sense that this window pops up since the tool path does continuously turn the B table on our pocket-NC, and there is a known limit to how far it can turn. However when I go to hit ok or x out of the window, it just pops up again, doing so repeatedly resulting in the code not posting.

I am using Mastercam 2024 with the Penta Machine Co. PocketNC post processor which is provided by Mastercam.

I have included a screenshot of the screen that pops for reference.

Let me know what you guys think about this problem. Thanks!

If you share the file I can take a look, I have the same machine & post

Yes this could be a problem since you are new you don't understand the different switches the Post uses to control primary positive or negative output. There may need to be a prewind in the operation to allow whatever toolpath the Rotational travel it needs on one the primary axis of rotation. Normally on a table-table machine the primary is the one with limits and the secondary is the one with no limits, but that depends on the builder.

Like Byte suggested a Z2G would help us help you.
