Nice, Ken but far beyond the repeatability of the machine when there is backlash and beam eccentricity to deal with but overkill unless carving a new Hubble mirror. The DVM gives me a 0.500 in kilo-ohms display, and one click of the jog dial is about 2 added or subtracted from that 500 ohm display. That one click of the jog dial in its finest per click mode is 0.0001". I can change the size of the jog per click in a 1,2,5,10,20 sequence which 20 is faster than it can move. Separate but logically identical jog wheels made out of the $20 MPJA dials for each axis. All on the replacement apron. Works well. Better than my eyes ATM. Had a new lens put in the right eye this morning. So I've a bag of eye drops to administer shortly, catch some zz's, then see how I feel as far as driving up for a post op check in the morning, around 25 miles one way. Not quite running into walls, but... Thanks Ken. > On Tue, Oct 16, 2018, 11:33 Gene Heskett <[email protected]> wrote: > > On Tuesday 16 October 2018 10:40:58 theman whosoldtheworld wrote: > > > perfect ... to next time ... > > > > > > bkt > > > > Yup, thanks. > > > > [...] > > > > -- > > Cheers, Gene Heskett > > -- > > "There are four boxes to be used in defense of liberty: > > soap, ballot, jury, and ammo.
