Anyone know what this cable is for?
I mark it with red box
Attach it to the screw, it is ground wire, help protect the electronics. As static charge could build up when the nozzle constantly squeezing plastic.

My printer doesn't even have such a cable. What's the reason? Is my extruder not grounded? Or is it solved differently?
@JohnGood this cable was added post-kickstarter afaik, due to CPU boards (that are plugged into the motherboard) getting fried by static build-up.
You could always add a cable yourself, see here for where it's connected on the other side: https://www.cetus3d.com/community/forum.php?mod=viewthread&tid=231&extra=page%3D2&page=2
