Well I started cutting some little Key Chains for my HALO Clan, www.sbgclan.com, they just played Bungie the writers last Wed and kicked the mess out of them the first game. Bungie wrote the game.

Drew the logo in Alibre, MeshCam'd it for the Code, CutViewer for verifying the code.

Saved it to the machine, got the Fog Buster all set up and off we go.

1/8" cutter, 20 ipm, .005 depth of cut.

Gets all the way though it, 2 1/2 hours later and than sliced though a ridge killing the piece. I also don't like the way it does the tool path. I think it would work better if it cut out the inside and than profiled around the outside.

It was looking great until the finish path, when it started to stich up and over everything. The edges got rough and didn't really clean up well. Than on the pencil finish it cut though some raised areas in two places and the center it ran around the points leaving material in the center.

Off to study G-code, any suggestions?

It uses a Rasta affect and I had the same problems when doing my Burton Snowboarding Logo, I was thinking too myself like ok, it looks a bit rough but it should come around and clean it up, well it didn't really do that, in some spots yes, in others no. And it seemed to go down in the Z in certain areas more then I would have liked.

Didn't Cutviewer show you it all going horribly wrong? I have produced a lot of duff G-code, and machined some of it, however when I've reviewed it in CNC-simulator, it's always gone wrong in exactly the same way as on the mill. I now always simulate 3D-jobs before cutting metal - half the time the estimated cutting time is so huge, I give up without even starting!

I really don't think you'll spot a duff cut in 20,000+ lines of G-code - you need an automated way to verify the G-code IMHO.

I use Cutviewer before doing anything, I never saw the dig on the screen. Now that I know were to look I may see it. but I would have attempted to fix the z depth before that happened.

I still need to see the difference in the G-Code from Dolphin, still attempting to get that worked out.

Thanks
