Answering to Andy and Gene, I'm tracking the position of the spindle (now simulated with this encoder but in the final machine I'll be using a 1024 PPR encoder) resetting the position counter after each index pulse and using that as reference for a new turn of the spindle.
Do you think it's better for me to only use one index pulse to set the reference and then count the position output to keep tracking of the spindle position and whenever I sum 1024 pulses I get one turn? I mean, not using the index for each revolution, only using it as a reference starting point.
