Always a consideration, Chris. But putting "Dell Dimension 745" into their search box only came up with psu's & that sort of stuff. No mobo's. I suspect its too old. And, while I thought a mouse was all I needed, but somethings still aglay, it will not run a g33.1 in a peck cycle. It starts down on the first stroke, cutting air, and spits out a following error. Slightly wierd, the first step down is about 16 thou. It starts down, and according to the dro, goes past the first move by about 2 thou and errors out, shutting the machine off. And nothing I can do will make it go past the first step in the while loop. The short routine: tap3-8thsx16tpi-hole.ngc: % ( tap3-8x16tpi-hole.ngc ) ( measure in inch's ) G20 #<_z_depth> = -1.000 #<_tp_inch> = 16 #<_inc_per_peck> = [1.00000 / #<_tp_inch>] #<_z_dec> = [#<_inc_per_peck> / 4.0000] S500 M3 ( start motor in low gear ) G1 f10 x0 y0 Z0 ( put it at touched off to 0.0000 position ) #<_z_tmp> = 0.00000000 ( start z_tmp at that Z location) G1 F10 Z#<_z_tmp> ( and put it there to start the loop ) (debug,z-tmp=#<_z_tmp>) (debug,inc-per-peck=#<_inc_per_peck>) (debug,z_dec=#<_z_dec>) o100 WHILE [#<_z_tmp> ge #<_z_depth>] G33.1 Z#<_z_tmp> k#<_inc_per_peck> #<_z_tmp> = [#<_z_tmp> - #<_z_dec>] (debug,22 z-tmp=#<_z_tmp>) G4 P4 (4 second pause to blow chips & buttercut the tap ) o100 ENDWHILE M5 M2 % And single stepping it, it never shows the line of code its executing in the code window, so I've no clue what line is the problem. And at some point, before it actually starts the spindle, the little window that shows what modes are in effect, goes totally berserkers for about 5 seconds, then stabilizes back where it started. By then it was time I rounded up some din-din for us, and shut things down for the night before my headache returned. Anybody that see's what wrong with that code, speak up! More than likely a forehead slapper... Thanks Chris & everybody. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
