Happy to help Steve. And thanks to your friend Bill as well.?
From what I understand the wire gauge selected for the long cable (you had said you measured it at 26') was pretty small as well - Bill stated that you guys measured a resistance of 3 ohms. That is huge. The average current the system draws while tracking is quite minimal - around 0.25A (Junior) to 0.4A... but the peak current with both motors can be as high as 3-3.5A. So the voltage seen inside the scope will drop accordingly (I X R - Vd).?
To others reading this - if you have the PGB note the system works extremely well - BUT like most anything else in life it has to a) have been installed properly (you'd be surprised how many were not)? and b) maintained properly. The latter I've not pushed but now that some of these systems are approaching 20 years of use maintenance should be done. Write to me or Bill Conrad, the new master of the ServoCAT (
Bill@...), for a list of things to check if you are having a problem as well as things to do for maintenance.?
