Excessive toolpath

Post by nmflyr »

I am designing a door model and the 3D view is as I desire, but when creating toolpaths, I use the roughing tool to cut away using a large bit, then create the finish toolpath using an 1/8 ballnose. The finish toolpath goes over the same cuts as the roughing path, and takes 68 hrs to cut. How can I make the finish toolpath only cut the remaining stock?

Draw vectors around the sections that you want the finish toolpath to cover, and be sure to Selected Vectors on the finishing toolpath.

Here's where an image would seriously help.

If you run a 3D Roughing toolpath over a particular area and then run a 3D Finishing toolpath over the same area the 3D Finishing toolpath will indeed cut only the "remaining stock".

What type of 3D Roughing toolpath are you using: "Z Level" or "3D Raster"?

Perhaps you could have two 3D Finishing toolpaths: one using the 1/8" bit to get into detailed areas and one using a large bit to clear less detailed areas.
