But thats a time sink like a black hole. I have used the G38.2 to record an xyz point map, on a 20 thou grid, of a P17 rifle floor plate intending to carve an alu replacement by using G38.2's ability to keep a log file, Took my CNC'd X1 mill about 3 days to do it at that high res. Which was not high enough to make a good replica, so that round tuit never got done. No way was I going to stand there turning cranks by hand, I could turn out the lights and let it do its thing. Check back daily till it was done. The folks who coded LinuxCNC have given us some pretty powerfull tools, so I used them. In this case, I should have used it to make a sand mold, but in what is now a 20 lb rifle, the importance of that ounce saved got lost. It doesn't count when sitting on a stump, waiting for a deer to come down yonder trail that you are downwind from. > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
