Do you you have a file you can share?
I use these paths constantly.

I could try it in MU2 for you, if you are reluctant to install it.
Mu2 is all bug fixes
It is very stable,much more than mu1
long shot...Try setting all your surface normals the same way and regen

Something else to check.

the large stock model in
It has sharp corners but all wall are 3 degrees
:crossing fingers: while mold is cutting

I was afraid that was the answer.
That would be a good thing to change with X7.

“:crossing fingers: while mold is cutting” Making statements like this to my boss on a one piece jobs is entertaining.
"I have a containment boundary and I tell it to sit inside but NOOOOOOOOO it goes outside the containment boundary!" Man up, this is how they do it in France.
"As far as your gouges go, go to your Linking Parameters - Leads - Make sure Horizontal Arc Entry and Exit are at 0.0. Any other value in those two boxes will cause a gouge now and then." I’d set my op default to 0.0 for this data field then put tape on the monitor over the location of that dialog box.
"The problem comes out when using the preserve 3D passes. It doesn't like vertical walls with sharp corners. Tried closed offsets and upper to lower and would get gouges (not always)." Trying to preserve 3D passes in a 3D tool path, the nerve of some people!
"If that doesn't solve it check out your transition parameters. I had it set to tangent ramp - gouge. Went to Ramp - Angle - 30 - gouge. Angle - 20 - gouge. Angle - 10 - no gouge." Found the sweet spot! Here is another op default to set. Get some more tape.
"But, the gouges on the vertical walls aren't really gouges, their probably the fact that the tool is tracing up those walls to the next cut. To eliminate this, you need to change the percentage of the tool diameter on the Keep tool down within on the Cut parameter page. Too big of a percentage causes the tool to trace up the walls to the next cut. Lower that percentage and the tool drives up and over these walls to the next cut."
I agree with this statement although it is not germane to this tool path. I came across this situation last week while using SF Contour and SF Parallel on the same faces in a curvy progressive die component, CPM4, using a 3.5mm ball and 3.0mm ball. The vertical walls appeared to have chatter in them. The solution was to semi-finish at plus .002 stock and use a slower feed on the semi- finishing tool then switch to a smaller diameter tool for finishing as this allowed for a smother entry into the vertical wall. Only two pieces on this job so I didn’t have the time to narrow it down as I probably could have tried down milling with the smaller tool first. Not enough chip clearance and flute length on the precision OSG finishing tools could have been a factor as well.
“I am cutting a die cavity and would like to start on the bottom and cut up. Is there a setting that would allow me to do that with Surface High Speed Hybrid toolpath.?" “That would be a good thing to change with X7.”
According to a PDF I came across: 3D HST HYBRID. Optimized cut Order. In Mastercam X7, 3D HST Hybrid Toolpaths now include a new Optimize cut order checkbox on the Cut parameters page. This option defines the cut order Mastercam applies to different cutting passes in the toolpath. Now all we need is Optimize Containment boundary , Optimize Horizontal arc lead in , and Optimize Ramp Angle check boxes.
Perhaps some of the new beta testers could comment on this as other changes to the toolpath may be in the works.
