Giveing up on the jig brace, I decided to make a wooden one as it doesn't have to last till the rapture. I laid out a circle, then contemplated how to draw this circle such that its position was offset half a mm for each time that it was drawn, until I got the proper depth of cut.
Without doing the arcgenm18 routine in 50 pieces of code, I tried to make a sub routine out of it by manipulating the y offset, but whilew it moved, it didn't want to do it in a straight line up the y axis, but wandered off the the right and got smaller. I moved vars around, but that failed similarly. So I got this wild hair to move the co-ordinate, then I could re-use the same subroutine until I'd hit the offset I wanted. But I stopped it as it was starting the 2nd semi-circle, which means the y coordinate had been moved what I thought was half a mm. But on further study of the docs, neither G10 L2 or G10 L20 take anything but absolute values. So this means I have to get the current y coordinate from the memory for P1's map, add my small var, and rewrite y with a G10 L2 y new value. Except I moved it 40mm with the first command, and now it says the first mpve will exceed the y limits. Then I noticed the - sign was missing too for y. Is this a place where I have to g53 g0 x0 y0 z0 and then rewrite the p1 map to all balls at that location? A shutdown, restart and rehome has not fixed it. Then reset y for each pass with G10 L2 P1 y[#5222 + 0.50000000] mm mode! And end the program with either a saved initial #5222, or another g53 etc etc? -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
