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

[Doddy]

If, however, I've missed the point - if the connectors ONLY plug in one way around onto the controller card then we need a plan B. Let me know.

They are the same as lipo battery balance connectors.
If you're gentle you can push on the tabs of the metal connectors with a stanley knife and slide them out of the connector block.
Then swap them over, slide back in.

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.
