Greetings all; I have the encoder built, and being the curious type, I mounted it after putting some flying leads on it, powered it up with 5 volts from the supply in the soldering station, and hung a scope lead ground on the - rail, and the probe on the A output. 5 volts DC showing. Reach over and start the motor at what s/b 755 rpms, crickets on the scope still a solid 5 volts, no noise. Move scope probe to B, same result. Move it to Z, stuck at 5 volts. I have read the Allegro docs thru, and see no references to any glue warnings.
Stop spindle. get out a number drill kit to measure tooth to device distance and get between 1 and 1.5 mms for A/B and around 2mms to the bit of screw that is supposed to be the index. So gear tooth to device seems like it has to be ok. There is some ambiguity in whats left of my mind as to which face is which. I have always assumed that the cross groove pattern face is the active face, is this wrong and I should turn them over so the smooth face is toward the gear? When I unpackaged them, I did not note that as it says on page 5, the branded face goes toward the gear because I couldn't find a brand on either face. Chance of them being some far eastern crap? IIRC, I got these from digi-key. Thanks all. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
