So by purely mechanical means, that would then be: 300 * 16 * 40 * [60/53] / 360, or 603.7735849 according to my TI-36X Pro. But thats about 5x what seems to be pretty close @ 125.xxxxx. Something, someplace is lying like a rug. But where? You got the hal file now, is it wrong? I just found the stepgen drawings and I think my hal file is wrong, the values presented by the .fb pins are not in the same units as .count's. And this needs counts. I'll fix that when I get it back together. Then maybe it will make sense. currently stepgen3.counts is -173640, while stepgen3.position.fb is 1380.7 > -- > atp > "A motorcycle is a bicycle with a pandemonium attachment and is > designed for the especial use of mechanical geniuses, daredevils and > lunatics." > — George Fitch, Atlanta Constitution Newspaper, 1912 > > > _______________________________________________ > 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.
