Good argument Eric, they are a bit large for that, but that does make them handy as crank subs on a cnc conversion. OTOH, hal can tie that together for those uses as its purely an incremental correction, functioning + or - from the default 100%. The dial markings will be out of sync, although some hal code could also fix that. I fix and sync the jog dials by letting the active time run out, then make the dial position the last 2 digits of the dro, then reactivate. Stays synched until you change the dial per step range next time. > Eric Keller > Boalsburg, Pennsylvania > > _______________________________________________ > 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.
