Help requested - installing end stop sensors onto my chinese 3018 Pro

[Doddy]

Dazp - the reason I posted what I did is because of this image from both Banggood and Aliexpress, there's a similar but less well defined image on Amazon. These taken from a search on RAMPS 1.4 End Stop from the URL OP provided that just didn't work for me.



Which shows a Dupont connector (non-polarised) at one end which allows for incorrect insertion into the controller card.

If, of course, the cable is different with the OP's switches and the appropriate mating connector has been used, but the pin order is incorrect - then I'd agree - depress the retention clip on each socket and remove, reorder and re-insert.
