Auto-leveling GT2560 Proximity wiring

Post by RMT » Thu Oct 01, 2015 9:31 pm

Has anybody wired a standard inductive proximity switch to the gt2560 main board, I couldn't find much info on the pins other than the picture that just shows where everything plugs in.
I understand with a regular switch it doesn't matter which way the wires connect, but what about when wiring the proximity switch ?
The black and the blue wire would it matter, or can I change / setup in marlin firmware how ever I connect them.

The underside of the GT2560 has the pinout for each connector - flip your board over to find out.

Assuming that you will be using the Z-Min endstop, the edge-most pin is marked 'V+', the middle pin is marked 'SIG', and the innermost pin is marked 'GND'.

If your proximity sensor uses 5v power, connect:

Sensor 5v -> Z-Min V+
Sensor OUT -> Z-Min SIG
Sensor GND -> Z-Min GND

If your sensor uses 12v, and has a floating OUT which is tied to GND when triggered, you will need a spare wire to the '+' side of DC IN:

Sensor 12v -> DC IN +
Sensor OUT -> Z-Min SIG
Sensor GND -> Z-Min GND

Try the 5v solution first, if you are unsure.

Can someone teach me how to wire the 12v input of the proximity sensor on the GT 2560 main board?

Then it has to a NPN sensor, if the signal from the sensor shud be - ?
