Is it possible to get a dxf from an sbp? I know there is a dxf2sbp program file but is there a sbp2dxf capability?

Tom,
In Shopbot control software there is a file conversion program. It will extract a sbp to a dxf. I don't think it will work on all sbp's but give it a try.

don't know if it is changed since last time i tried it but with that conversion you ned to be careful because not only did it show and convert the toolpath cut lines but it also included the carriage moves as tons of extra lines. see pic

Also your lines will be off by the radius of the router bit and multiple passes will show up as duplicate lines.

I believe you can select the lines you want to export, select "file/ export" and create a dxf and save it to a given location from there.

You have to select the linework first.

If I understand the question...Tom has the .sbp file but not the .crv file. In that situation you do not have the option as to what you can select.

Tom...
The SBP to DXF converter will do what you wish. Thats the good news. Bad news is it will also do what Jack and Steve note.

The converter is indescriminate. It will take all movements from the SBP code and convert to DXF. Move actions, jog actions, multiple lines for multiple passes. And the paths converted will be "center of bit" lines, not part outlines, so you will have to offset either in or out, by the bit diameter to get the original part outline. (you will need this diameter for accurate parts)

Not as user friendly as saving the original design file, but as a last resort, very workable, especially if you have an idea of what the original design looked like. Node editing is your friend!

To answer your initial question...Yes there is a sbp to dxf conversion and yes it does have its limitations.

Thank you very much guys. I was trying to find an old cut program (preferrably a crv3d) but noticed all I had was the .sbp files. This will help greatly, thank you!
