Hi,
I'm wondering if it is possible to get enough back EMF from a stepper motor running at low speed, to process thru a pic, the number of steps it has gone thru to display the results to a 5X7 segment LED display.
I'm basically trying to avoid the coupling of an encoder to the motor's shaft.
Would it be accurate??
System is to be used on CNC system with visual display so operator has visual confirmation of machining progress.
Thanks.
