When using surfacing toolpaths we must be very carefull to turn off arcs in the filter setup window. If we don't strange things can and do happen (crashes, weird moves) that may or may not show up in Verify. Our rep said there is a new Fadal post coming but so far we haven't gotten it. Anybody else have this problem and what have you done to bypass it?

I have seen a problem somewhat like what you describe. Except it was on a Cincinnati machine(custom post). We finally found that the main problem was when the machine was trying to make extremely small arcs. In the post, there are two lines you would need to check. That is, if the post for the Fadal is anything like that of the Cincinnati one. Here is what we found:

arccheck : 1 # Check for small arcs, convert to linear
ltol : .050 # Length tolerance for arccheck

The first line was already set to 1 (Yes) but the second line was small. I can't remember exactly what it was, but it was less than .005 I believe. The way I figure, is that the second line checks to see how long the arc is, and if it is under .050 in this example, it converts it to linear. After changing that, the problems went away.

Sorry for digging up an old post.

Also make sure your machine can do arcs in the XZ and YZ planes as well as the XY plane. If it doesn't, you can set a switch in the post to disable it in XZ and YZ. (and XY if you like )
