Attached. Or was, by the time it was base64'd, a 273k jpg was 380k and too big. So I removed it for a resend. I had it clamped to a planed flat cherry spoilboard, but had to heavily modify the code because even with a nice flat 3/4" cherry under it, it was still a mm+ out of flat with the 6040 bed. So I had to do some commenting and adjusting of the code to get it cut completely free. > And how did you write the gcode? By hand, with some help from argenm18.py for the circular stuff. I have the beta freecad, but not the knowledge to run it. So I write one good line of code, or a short paragraph, and wrap it in a loop. At the moment its still only about 100 LOC. > Did you use the axis backplot to check the curves? Yes, but the backplot wasn't as accurate as the mill, so there is a detectable glitch at the root of the handle on both sides. So I had to re-write all the whiles to make 2 final passes deep enough to actually cut it loose. I need to make the other wrench yet, so I'll be hacking on it to do that, and then I will post the code. I also intend to further lighten them by removing quite a bit of the handle thickness which I'll do in a separate .ngc file. And some of tomorrow is wasted, getting fresh rubber on the truck. And my 8 oz coke bottle for mister supply needs swapped for a bigger one if all the code is enabled at one time. I had to refill it twice. Now I hope it will get past the size limits. The smunched pix is 273k, any more smunch and the color goes to pot. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
