Hi,

The problem that I'm running into is the finish toolpath on a circle does not create a perfect arc, instead it is a series of flat faces. I thought that this might be a preview resolution problem in order for it to run faster, but a quick test cut resulted in the same problem. Does anyone have any ideas or encountered the same problem?

Also, when performing 3D milling roughing is it possible to keep the tool down between Z levels? I was able to program this in the HSM module, but in the 3D milling toolpath I'm unable to get this to work.

Great forum by the way, hope to contribute!

Thanks

Try looking at the facet tolerance value. You'll see quite easily in the simulation the difference between a high and a low value. Try comparing 0.1mm to 0.01mm and what was a series of straight lines with the 0.1mm value will turn nice and smooth with the 0.01mm value.

Also I always check the 'arc approximation' option as this will help keep the program much smaller.

Don't ask me any technical q's on this as I'm still learning myself :)
