Steering Gear what is it for?

I have a GRBL laser controller and one output I cannot find what it is for. It’s bugging me can some one help. It’s marked as “Steering Gear” ?

Are you talking about a remote pendant socket on the controller board?

If my guess was not good, then an image of what you are talking about might help someone help you.

Hi thanks for that. But no I do not think so.


Another picture….

Couldn’t it be an output to switch between low or high airflow to complement the Air assist?
These Chinese translations are often misleading.

Google through this up if it helps

This was my first thought too, but I think this applies to some kind of CNC milling machine. Milling machines need Z axis. This board only have X and Y so it maybe something else… :thinking:

That board looks like a custom manufacture unit, like my iCube board, made just for the manufacturer. I would hook a meter to it to see if it supplies power or is a switch. The connector is too small to be much else. Only the manufacturer knows for sure. Contact them to learn what they will say.

Thanks guys. Very interesting particularly the Far Eastern bit.
It’s from a Lunyeetools S1 3040 laser engraver and no I have not yet put a meter / scope on it yet. But soon. Thanks
