On the frame of the cable reel, there is a guide that the cable goes through keeping the distance from the center of the reel to where the cable unspools at a constant 6". Shouldnt this be easy to calculate? Im no math guru, but it seems to me, that once I calculate how much one click of the encoder moves that cable leaving the reel at that guide, I should be able to enter that number into the counter section of the serial print, am I correct? Or am I overlooking something?
