I assume you are talking specifically about dynamic and Opti toolpaths, not the entire 2D/3D HST suites?

Email is fine if it is less than 50MB

Can you share an application for 2D HST Rest with 'Use core Mill passes' checked on?

Does anyone use the 'use core mill passes' check box for 2D HST Rest? Does anyone use the 'use dynamic core mill passes' check box for 2D HST Dynamic Rest? ?

ftp.mastercam.com Right click, select login in, use anonymous in the lower left. Put it in the 'to mastercam' folder

That's fine drop it in there, send me a link

I am currently involved with Stock Model, can you please send me the part file?

Can I have the file, we've seen this and fixed it awhile ago....

A stock model operation is like any other toolpath operation. Create it from the toolpath drop down menu, go into it's parameter pages and set it up. Control it's display like any other toolpath operation. YOu can even use it on Verify as an option to define Verify initial stock shape...

Mill license only, not Router (coming). Mill Toolpath drop down menu in X6.

2-5 axis work, custom tools are fair game. Transform is not fair game yet...

Use the same button you use to control the toolpath display

If you select a CAD file on the toolapth type page it can be used in one of two ways. If you are not useing the CAD option on the rest material page it is treated as drive data in addition to you rselected surfaces and solids for drive. If you are using the CAD option on the rest material page it will be used as rest material shape, not as drive data. Pretty clunky. So in comes stock model, just create a stock model, load your STL as intial stock shape and accept the form. Now you have a stock model you can reference on the rest material page using the 'One other operation' method. Better yet, stay out of verify and use stock model to process the toolpaths you processed in Verify. Now you don't have an external STL file to manage, if you tweak the toolpaths that created the stock model it just needs regening along with the rest rough. If you tweak the toolpaths that were used in your method you have to now verify them, save a new STL and load the new STL into the rest rough toolpath, a bit clunkier....

Name the stock model. if you do not name the stock model it takes on an operation #, not sure why it chose 42, but naming it will list it's proper name.

Have you tried OptiRest with step-ups disabled with a more traditional smaller step down?

Neurosis, We have thought about ball tools and chose to support them like flat endmills. You're basically expecting a ball nose to remove cusps after roughing or to avoid leaving cusps on flats, that's a lot of unnecessary motion due to a tooling choice. Furthermore, we cannot predict or detect where the cusps are to ensure micro-lifts avoid them. The best advice I can give you is to calculate the cusp height for your cut condition, which is simple since your on a flat floor, and enter an appropriate micro-lift height. Cheers.

Bullnose are treated like bullnose, flat are treated like flat, ball are treated like flat. To treat ball like true ball or bull is not going to yield very effective toolpaths. Dynamic motion is designed to run bull or flat specifically, it's a full depth roughing toolpath. If you want to see what you ball would yield, define it as a bullnose. So a 1/2inch ball could be defined as 1/2 bull with .245 rads. But your max stepover will be severely limited due to the small flat of the bull.....

That "stray move" is a micro lift re-position move, a non cutting move if you will. You must of had your retract behavior on the cut parameters page set to "never". In addition, understand what "use core mill passes" means. It means consider the boundary to be the edge of material and approach from outside it, so the tool is allowed to mill outside it. This similar to 2D HST Core Mill and 3D HST Core Mill behavior. You remedied your "issue" by turning "Use core mill passes" off because the boundary now becomes a true containment boundary just like 2D HST Area Mill and 3D HST Area Clearance.

Another trick to reduce file size is to do something like move your entire part and then undo to put it back so all your ops are marked dirty. This will greatly reduce the file size.

Very well, thank you.

I am interested in this file, can you email it to me, I'd like to try something in X6.

How are you defining your rest material? Are you adjusting to ignore small cusps at all? Is the rest rough using the same step down, stock to leave and tolerance as the toolpaths to shape the stock prior to rest rouging used?

Saving an STL from Turbo is not accurate at all, its an approximation. You must use the run tool mode to save off a usable, accurate STL file.

It supports steel. Just make sure you enter the correct FPT and SFM, the initial defaults are just hard coded defaults. Also, ensure you use pitch for entry and set the separate appropriate entry feeds and speeds found on the entry page.

If it's a small part, tighten the default .002 shading tessellation tolerance.
