This is somewhat random as I'm working on retrofitting my old Lagun FTV-3 CNC, which had a '79 vintage Bandit control when it was originally sold.
I'm wondering how the machine knew what the Z-axis (spindle) limits were? When I bought this machine most of the bandit stuff was already stripped off, I can see the holes where the original X- and Y- axis limit switches were mounted, and I'm in the process of fabbing up a plate to mount some Honeywell sealed limit switches in that same location.
But the Z-axis, I can't for the life of me see where any limit switches would have been mounted originally. How did the computer know where the travel limits were?
Not that it matters, since I'm putting all new limit switches on all axis, but I'm really curious to know how the Bandit knew it had reached a travel limit on Z.
