could someone tell me if I can hookup a water pressure / sensor to a control board in side of a k40 laser cutting engraving machine the control card says that you can used to control exhaust fan, water pumps and other external devices here is the picture of the card I am talking about it uses a 2 pin small like portable phone battery plug I thank you for your help
I have seen this diagram suggesting that to to there is a control port as you suggest.
I do not recall anyone using it yet but expect someone will post if they have.
There are two issues to solve:
-
What does the output electronics look like. This could be found by tracing the circuit backward from the connector.
-
When does the output get asserted by the firmware. This could be found by connecting an indicator on the output and running the machine through it’s states. When we know #1 we can determine what kind of indicator to use.
I can solve #1 when I get home tomorrow but #2 needs a machine with a stock card. Mine is converted.

what is the switch machine switch
I don’t have that switch I think it’s the main power switch.
Lots of pictures. What are you looking for help on?
@donkjr I thought if you saw the pictures you would be able to see if you thought I could plug the water pressure sensor on to the laser card the first picture
@Dale_Capen Not sure I am clear on what you are wanting to connect to what.
A water flow sensor typically connects to the LPS not the controller.
Search the forum for this hookup and there is lots of info here:
