SolidCam 2015 with Solidworks, Haas VF2 mill. . Almost every time I run a "SolidVerify" simulation, I get a "Clash between holder and machined stock is detected" message, or some other tool crash message. This usually happens on the first pass of the tool when only .25 is engaged on a 1 inch tool. Why am I always getting this message when I don't see anything wrong.?

I don't have any tool holders in my library. Actually there is one that says 3/4 end mill, and a small icon "1 inch long"
Maybe that is the default tool holder for all.? I can't seem to find any other library of tool holders, should I have those, or is there somewhere to download them.

Thanks for any ideas.
