Hi, I'm thinking of putting limit switches on my X Y and Z axes, and am considering using hall-effect sensors on the machine frame with little magnets mounted on the moving axes.
Has anyone done this or have any input on doing this?
It seems to be a good system with no moving parts and since I don't machine ferrous metals I can't see a down side.
One of the best features is that they allow overtravel so I can put them some distance back from the end of the travel. So even if the steppers have had a major misalignment it can be easily detected with no chance of hitting the end stops.
