Thanks for taking the time to reply, I would love to do servos with a closed loop if possible. But I am not sure if it is feasible or necessary. Time is my enemy, I spend 7 days a week working which only leaves a few nights for this.
there doesn't seem to be to many places in the uk to purchase the hardware I need.
what I do know, the turret is probably going to give me some grief setting up and the encoder on the spindle is going to be another pain.
The pdmx boards seem a good option as they can plug into each other with ribbon cables etc, but USA supplier. I guess there is no recommended setup, I guess I just want a no nonsense setup.
