optical-endstop-cable connector

thingiverse

Easier connectors fail too easily. This new design goes all the way to the bottom. Also, switches that shut something off must be Normally-Closed, and start open by default. This prevents anything from moving while a cable is disconnected or broken. Proper function is achieved through software by inverting the signal. If this optical switch loses power, it creates an undefined state. I have successfully created four versions using my 2 Single-Lead Thermistors, but I'm stopping development since I got mine to work. Please finish developing it. Post Script: An allen key can be used as a limit for mechanical endstops until the optical ones are built in.
