Motor using Encoder as Limit Switch?

[DonRotolo]

Mechanical switched that detect the min and max position will be far better of a solution. Just position the switch such that...

1. It does not get damaged if the motor exceeds its position (e.g., to the side, not 'blocking' thr path)

2. Put hard stops so that if it does exceed the limits, it won't break, but stop.

In fact, no matter the method, #2 is always a good idea.
