I hope someone could help me with that, because I can't find the answer in the forum.
Can I use this flow meter (
http://www.amazon.com/gp/product/B00ATN ... UTF8&psc=1 ) or this one (
http://www.lightobject.com/Water-flow-S ... -P541.aspx ) in the 3 Axis Laser Interface PCB?
I see in the users guide that Bart mentions an advanced water flow control by using the 3 ports on the water loop conector , but I can't figure it out how to connect the sensor and why it is always giving me normally closed contact.
Thanks in advance
