Well, running into more problems because of the too high bolt on the bottom right of the nozzle holder.
Just trying to calibrate the nozzles, I will hit it Multiple times. I added a final step to the load process to move the nozzle back down to a safe Y position, but then when it goes to unload, it whacks it again. It looks like I will have to have it first move to a single, safe position, then go +Y to the start position for unload. So, I really have to add two steps to EVERY nozzle load and unload, start at a safe X,Y,Z, move the the nozzle from there, do the load or unload, and on a load, move to the safe position again. Wondering how short I can cut that bolt and it still hold...
