Hello - I am building an indexing machine with a stepper driven table. The machine will be loaded and unloaded from one position and then index. I am planning on 6 stations so as mentioned 1 will be load / unload. Station 4 will be the machine action and all other stations will be idle or no action to the product.
When the machine is started, I need to find a home position since a stepper looses this at shutdown or worse power failure. I am planning on a mechanical limit switch that will be triggered by a peg as the table spins.
Is there a better way of doing this? Do I need to worry about wear on the switch? If I go with non contact type probes, how repeatable will they be?
