Help with CNC 3018 from Banggood

[Doddy]

My switches are wired as NO and when I check the voltage across the + and - pins, I get ~2 volts and if press the micro switch, I get 0 volts. From all the information I gathered, the bottom row of pins are all to ground???? Before changing my switch wiring to shielded wires, I tried, as suggested on the internet, to add a .47µF capacitor across the micro switch………nothing.

Aha, thanks to Kitwn for making me realise that you're already well aware of the pin layout on the board - I'd missed that bit of your reply in my haste to reply. Hopefully you should be able to understand my earlier ramblings and ignore the bit about identifying the ground-returns on the board.
