Okay Russ.
I did think about something like that, but I need to be able to tell the nozzle where to go during my tool change, for each respective tool. I was thinking that I could get an Arduino and program the positions into it an also have an adjustment knob that goes along with it. That way all I have to do is give outputs to the Arduino to read as inputs to move to exact positions. There's more than 1 way to skin a cat, just trying to figure out which is the best way.
Thanks for all the input, very helpful.
