Background
I'm in the process of a retrofit with the Acorn board to a Boxford TCL 125 lathe. I was intending on using the DC spindle with Lenze 530 driver and feeding the analogue through an opto isolator. I have already fitted an encoder direct to the spindle for this purpose.
It occured to me that using a Servo for the spindle motor would give better torque at lower speeds and could use the encoder on the servo driver to feed back to the Acorn.
Either way the spindle would be belt driven from the motor.
Question
Since the encoder on the servo is indirect to the spindle. Am I better to use the encoder directly attached to the spindle or use the servo encoder Feedback?
That is assuming the quadrature output of a servo drive is compatible with the encoder input of the acorn board?
Servo Spindle encoder options - non direct drive

Thank you Marty,
As simple as that! 1:1 drive Belt you've made me a happy man Ive been going round and round it for days and always missing the most simple solution.
Many thanks
Ben
