Inside Corners not cutting correctly - CV setting?

[dameronw]

I have been cutting out some speaker parts lately, and the CAM is driving me crazy. I'm not sure if it's a mach3 problem, or Vcarve, so I'm posting here as well. Sorry in advance if that breaks rules, but I just don't know where the problem actually is, and therefore where to post... I would really like to get this fixed though.

I have a series of pockets, and inside profiles, where the software is either eliminating a fillet altogether, only doing a partial fillet where it should be a full dogbone fillet or T fillet, or on inside corners, on one side I'll have a nice sharp corner, but the next one it will just turn into an arc.

Some of these were cutting just fine, but then I would regenerate a toolpath for some reason, and it would have decided to turn a T-fillet into a plain old corner. If I redraw the exact same geometry, and then regen the toolpath, it will cut fine the next time. Go figure. Some of the features though, like turning a shallow inside corner into an arc, it does no matter what I try. The simulation of the toolpath doesn't show it, but the finished product sure does.

I'm in CV mode in mach3, with the other settings off. Attached is a screenshot of my settings...

I just upgraded to this router (4x8 ez router) and it is superior in all ways to my old one, but this bug is really getting to me...

Any ideas where to start?

Aha, I think I have fixed it... I tried messing with my CV settings. I turned 'Stop CV on Angles' to 'on' and it seems to be way better. It's value is set at '0' right now - where doe people recomend that be?

Depends, but 89 is a good start.
