Choppy Optirough toolpath

[Sigurd]

Haas Mini Mill 2, Mastercam 2021. I am having a really hard time making this, and a few other, high-speed toolpaths run smoothly. I have played with arc filter settings, smoothing settings, entering G187 P3, and my toolpath is a choppy stuttering mess. Could someone take a look at my file and see if I'm missing something? Thanks.

What tolerance are you running your arc filters

I'd set them for G17, G18 and G19 with a 50/50 ratio and a tolerance of .002 to .004

Waaay tighter than .002 - .004". Loosening them up improved things dramatically. Thanks.

 G187 P3 is a finish setting on Haas.  You will want to use G187 P1 for the dynamic roughing cycles. I usually have my arc filters set at 33% cut and 67% line/arc with a tolerance of .001 and get pretty smooth tool paths with those settings.

heres a great video that the haas team made on the G187 topic, it explains how and when to use those codes in a very detailed mannor https://www.haascnc.com/video/tipoftheday/lwujoXvgGzA.html

also i assume that your machine would have high speed look ahead enabled but if not i would suggest getting that added to the machine if your gonna run a lot of dynamic.
