I have 2 files that did not work correctly.
E Knife does a 360 degree turn while it is still moving and in the material at the point indicated in the picture.
I removed a point in that area for E Knife 2 and the tangential knife does not turn at all.
Mach4 version 4517
ESS version 260

Hi Bill,

I don’t know if this is any help but…

The unwanted 360 deg. rotation issue was mentioned in an earlier thread and I was able to replicate the same problem.
I think there were a lot of changes made in Mach4 build 4517 and although the ESS build 260 addressed those changes there may still have been some issues.
I changed to Mach4 build 4571 and ESS build 268 and was no longer able to replicate those unwanted 360 deg rotations.

Perhaps Mach4 build 4612 with ESS build 272 may be the way forward.

Tweakie.

Tweekie,

Thanks.
I will try it.
