Laser Engraver Forum

My question is simple , I bought a water flow sensor at lightobject.

I want that if there is no water flowing so it will cut the laser !
Is there someone who could tell me how to connect it, please ?

It is just a switch. When the water flows the contacts close, when no flow the contacts open. I bought a flow sensor some time ago from Light Objects and couldn't get it to work. I don't think the pump I had at the time had enough flow or pressure. I would test to see if it works before you install it in the unit. if you have a good pump be careful not to squeeze the lines in case the tubes break free and spray water everywhere. How to hook them up depends on the unit, but most units have a water sensor input.

Hello Mcbride19, this is Nolan from ThunderLaser, hope my suggestion can help you.
if there is no water flowing so water flowing, the machine will stop working. right? it's very easy, you can set it from the software.
For example, we use RDC6442G controller and RDWorksV8 software. about how to set it, please check the attached picture.

I don't know what controller and software do you use, but I think you also can set it.
Have a nice day.

Thanks all but what I need is the wiring diagram.

I just would like to know how to wire it to cut the laser if there is no water flow.

The software isn't important, it's the hardware that is the most important, it's the task of the hardware to cut the laser if there is no water flowing not the software.


@dean448: I'm going to test that before going further. thanks !

@Nolan Yang : i'm using moshidraw and moshilaser, this function is on your software, so it can't help me !
