I have different voltage at pin groups exactly according the manual. And I have 5V at left middle pin.

At least I know that Andy and Viesturs had their encoders working. Maybe it's really a pinout, but I'm 99% sure it's not. Maybe just some incompatibility, though it's hard to believe too... RC + Shmitt can't break the signal too much. If I do not find a solution, I connect the encoder directly to 7i43 I hope to be doing that myself in a few weeks, with some small linear > motors I'm building. > I should say I was surprised how simple are these motors. Just a rod with magnets inside, and several coils in the forcer. And this motor with 20x250mm rod and 40x40x90mm lenght forcer they sell for $500 or smth. Now I think about making them myself. So any details on this would be useful. Any links for your motors. Andrew ------------------------------------------------------------------------------ For Developers, A Lot Can Happen In A Second.
