efficiently cutting curves

[endgrainguy]

I'm totally new to CNC world, and using my new machine to do woodworking joinery. This is the code and drawing it's made from for cutting dovetail tails for half blind dovetails. Spindle is used in horizontal position, and z and y are reversed from usual position.The tops of the tails are rounded over to match radius of the dovetail bit used to cut the sockets they fit into. I"m wondering if this is interpreting the curve efficiently --it seems slower than I expected --maybe 30 seconds of little sputtering motions to cut these two little curves.I know there are issues I don't fully grasp about the drawing and CAM set up for curves, and I"m sure someone knowledgable about this could tell in a second if I have done this the bveest way. I'm using Vcarve pro as CAM, and DesignCAD V15 for drawing. I"m beginning to realize Vcarve is not the best for joinery work, as it gives little control of tool path (Can't set start points).

Try this.

The problem with the code is that it is using small linear moves instead of true circular interpolation. That is why it is slow and jerky. I didn't notice though that in a couple of spots it did use G2 (clockwise circular interpolation) so that show that it is supported. I think your problem lies in your cam software.

DesinCAD created the .dxf with the straight segments. Try to figure out how to get it to output arcs in the .dxf.

Thanks for checking this and the replacement. Much smoother, fewer code lines. Easiest solution for me is to draw the fillets in V-carve, which is easy enough. I"ll check with DesignCad experts for a method of generating arc codes, but maybe just letting V-carve do that is easiest of all.
