Hello, I have this Chinise CNC for a wile and would like to "update it" with endstops - one for each axis.

My board is GRBL 0.9j and there is 3-pin inputs on it for each axis (see picture below).
I have no idea how to wire them to the switches and how to activate them in the software - Universal Gcode Sender (UGS)

Could You please give me some advice?

Thank You in advance
Best Regards

Hello,
I think you must have some USER manual for this CNC controller, micro (end switch) switch, have 3 pins. Pins are ( NC. NO. C (you wired 2 of them C and NC or NO.). You can google it - how to wire ( micro switch wiring). You have also a homing sensors, which are more expensive, but high accuracy, repeatable and reliable hardware and no mechanical parts. Also sensor have IP rating:IP64.
You can read more about sensors on:

Thank You for the fast replay.
Unfortunately the only info about the controler that I found are this few pictures which are not so helpful.
Thank You for the proposals but at this moment I don't want to invest more in 200$ hobby CNC

I wil try some more things as other software or/and different wiring ans switches and we will see then.

Thanks once again
Best Regards
