Well I think its fixed. I marked and then messed with the adjustment pots to see what each did, nothing from the A-0F, B-0F or the Z-0, but the one with a CS on it seems to be what I needed it almost seems like its a sensitivity level adjustment, I'm guessing that it works all 4 of the C outputs but I just turned it a bit at a time to see what changed and eventually I got C2 to light when the motor is locked in. I found that if I went to far C1 will stay on through the entire revolution of the motor, so I backed it off until that one worked again. I put it back into the machine and no hissing, and the following and gain error matches the Z and Y axis perfectly now. Thanks for all your help Al!! I still wish I knew what the other adjustments were for now, but I guess thats for another day.
