I don't have your version installed so can't tell for sure, but this might be the update that added that ability.

Bill,

Thank you so much for the drivers link. I downloaded version 1.102 and can now tool path an open vector. I haven't tried the extruder yet, but I suspect that it will work much better... Cheers!

I've been using the extruder a bit and have it working except for the multiple passes. How does that work? Nothing I do seems to make a change in the maximum depth of cut. Thanks

Guys...
Got around to cutting these today. Gnarly ol' pressure treated decorative rafter tails. Over 250 to cut, 13 at a time with the extruded file shown above in preview. A year ago I wouldn't let the green stuff touch the Bot. Gotta pay bills now. Here is a batch just cut.

Gary, those look like 2x6's..!? Just how long was that bull-nose bit?

I found that the first pass likes to plunge to the deepest/lowest level then cut across. So I need a bit which is the material thickness plus some otherwise the shank will make contact with the .75" material. (The cutting edge of the bull nose I had on hand was only .5" tall) Good thing I tested this on a tacked down piece of MDF!

I haven't tried this yet but since a bull nose bit will leave a radius and not a nice crisp sharp edge I was wondering if a v-carve bit of the same diameter as the specified bit in the parameters would be able to get into the "finer" lines of moldings and such? Any thoughts on that.

John...
Actually they are 4 by 6's, and fine cabinet lumber, too. Ballnose is 4" long with 3.25" below collet. cutting at 6ips with .05 +/-stepover.

I cant help much with the pro's and cons of 3D cutting as I dont do much, if any. I am sure that the more knowledgeable will chime in.

I couldn't see those cut any simpler way.
Must smell sweet!
Just Imagine your cutting 4x6 cherry.
