You said: That is a definite sign of a short somewhere. I would look at the simplest start which would be your limit switches. They use the same 5 volts that is used to enable the power supply.

Not exactly but we will give you the win!

Besides no-one should be chopped liver! :slight_smile:

I said: if the LED on the LPS is not lit (depending on your supply type) that suggests the 5V is not working or perhaps it is shorted to gnd by the connector.

@donkjr Thanks! I know better than to split hairs with you. You would think I would learn!

@HalfNormal … that’s no fun! I could stand on my head again?

@donkjr Do not worry, I rarely know when to stop. Please, no more gymnastics! I do not you to get hurt!
