I have an Alpha with a spindle and an ATC. Noticed the machine was traveling kind of high in the Z on the way to a tool change and sure enough the spindle was not where it was supposed to be to put the tool in the tool holder. Ran C3 again, no help. Figured out the Z target bolt had slipped on the back of the spindle. My question is: Where is the target bolt supposed to be. I've looked through my directions and I can't find anything that calls this out. I understand the exact placement probably doesn't matter but I assume it needs to be between _ and _? Thanks
