That tool is your brain. I do some woodworking too, and I'm quite fond of the Green & Green style of furniture which is basically a huge box joint. But I use cylindrical carbide tooling, and write my own gcode to carve those joints in either mahogany, maple or even white ash but it really shines in mahogany with ebony buttons hiding the screws. White ash, or maple with ebony button covers looks odd, cherry I think would look much better against the lighter ash or maple. Writing gcode is not THAT hard. I, by percentage probably write 90% of the gcode I used here before I bought some 3d printers. > William Cheers, Gene Heskett. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

One still needs software for previewing G-Code, and there's the issue of the firmware I'm using, Grbl, not having loops and variables, making any direct coding of G-Code, rather tedious. >I do some woodworking too, and I'm quite fond of the Green & Green style >of furniture which is basically a huge box joint.

While I can do that, it isn't a solution which is scalable in terms of other folks using my designs on different machines. William
