Dynamic mill crashing/alarming when filtering active

[Pgreenlaw]

I have been having an issue lately when I try and turn on filtering with a Dynamic or Optirough toolpath. I would not consider myself an advanced MC user, but I have been programming with this software since 2019. I am 3 months into a new shop and trying to figure out what is going on here. Since I have started programming, I have always activated filtering to reduce code size when using a Dynamic path. When I activate filtering I get reduced code, but when it runs in the machine it will alarm out with some MASSIVE I/J values, or try and plow thru the part. If I turn off filtering and repost it works fine, just sucks up a lot of memory and has extended loading times into the machine. This has happened on multiple machines and I'm trying to figure out if its a post issue or if I'm doing something wrong. 

 

Below are screenshots of what I activate with filtering. Also a screen shot of G-code showing with filtering on.

Adjust your min/max values for Arc size. A 100" radius arc is way larger than you'd ever practically want in your program.

Try a min of 0.01", and a max of 8."

Also, your Arc Breaking in the Control Definition is likely set to break at 90-degrees. Change that to 180 degrees. Why? I have seen arcs with "just over 90-degrees of sweep" cause issues. Say you have an Arc with 90.041 degrees of sweep, and it gets broken. You have a leftover piece of Arc, with 0.041 degrees of sweep, likely to be a problem.

Great tips!! P.S. I'm on pt 1 of your new curve 5 axis youtube videos and it's already been very informative. Really good stuff, I appreciate it.

You are correct, it was set to "break at quadrants" Over the weekend my MC rep sent over a new content file and I noticed it is now set to "dont break arcs" Which I was told should take care of the issues.

Current new settings:
