Poser for the servo experts out here...
I have a Servo speed regulator with reversing capability.
1) When I connect two servos up to the regulator and reverse one channel the two servo operate perfectly in sync with each other step for step.
Wanting to use a simple y-connector because have no need for the speed regulation in this application.
2) I take one servo and reverse both the motor wires and the potentiometer wires so the the servo is now reversed.
3) I connect up both servos to a simple y-connector and they both travel the same direction as wanted.
Problem: It is now apparent is that they are no longer perfectly in step with each other and the end points have changed.
I'm thinking this is due to the pot's not really being linear. I have returned the wiring to normal on the same servo and it again returns to being in sync with the non-reversed servo when run though the regulator. Just to make sure that it was not a fluke.
I have also tried this with several servos to make sure it was not just one mismatched servo. In all cases when reversed at the motor and pot they are no longer in sync. I went one step further and connected up one of the servos that I manually reversed to the speed regulator and reversed it back(in the regulator) they are again no longer in sync. It would seem it is dependent on the direction that is used threw the motor or pot.
Any suggestions on how to manually tune a reversed servo?
