Greetings; I appear to have a math problem. Simply stated, the slot interrupters being mounted on .1" centers, almost exactly matches the slot spacing of a 50 cycle wheel at this diameter.
IOW, A and B will be so close to inphase as to be about as useful as those small appendages on the belly of a boar hog. Much the same situation still exists if I move the outside ones an additional space apart on the perfboard. So, a 50 cycle wheel is not viable. Thinking it thru, if I add the additioonal .2 to the spacing, then the curvature of the rim of the disk will I think, allow longer slots for both A/B and the inner track index from the center opto. I can make a higher cycle count wheel, but there should be a rule of thumb that would give me a near perfect quadrature once the slot opto spacing is set. Where can I find that magic rule? Last time, I measured it with LCNC in sim mode, touching Y off at the center of the slot that represented, say 3 cycles above the y=0 slot, and then went straight down to (IIRC) the 7th slot to measure the center of it, hoping to arrive at a total run that ended in .X5, which would appear to give the 90 degree quadrature needed. I added or subtracted the cycles until that condition was met. Should I resort to that again, or is there math to do that now. In any event, I am out of the disk making business until I find some brushes for the motor on the toy mill. Those have the equ of half a million miles on them, and are failing rapidly, needing removed and the spring given a stretch at one point today. Thanks all.
