Hi, Does anyone have a schematic for the Rhino Mark III Controller? I acquired a Rhino robot arm and the B motor encoder channel seems to not be working properly and I'd like to try to isolate which parts of the controller board are unique to the B channel. Alternatively, if there are any Rhino experts that could help point me in the right direction, that would also be appreciated. I think I've isolated it to a problem with the controller and not the motor/encoder or the teach pendant. Using a scope, the output from the B channel is very different than the other 7 channels. Thanks...Win
