Prusa I3
MKS 1.4 Board
Repetier Host Firmware


I recently picked up a MKS 1.4 printer board for my prusa I3 looking to upgrading my old melzi board mostly because I wanted to use dual extrusion. I have everything wired up and working fine except for my end stops where im stuck I tried looking online haven't had much success, I have mechanical end stops 2 wire (black + red) and on the board where the end stops go I have got a slot for 3 pins im not sure how to wire it correctly I would have to make a plug and crimp the wires which Is no problem just not sure which pins I should be using any help would be appreciated thanks in adavance

Cheers

On the board it has the connections labeled as + - S.
This means: positive voltage (normally 5 volts), ground and signal.
Your endstops don't require power, so you can ignore the + pin.
You end up with - and S and since it's just a dumb momentary switch, it doesn't matter which pin you connect to which end of your microswitch.

your the man thanks a lot everything is working now
