Adding a water flow switch to a K40
« on: November 10, 2017, 01:59:34 PM »
My K40 came with a flow switch that worked some times and not others so I decided to replace is with a better quality switch. In the attached picture you can see that the water line going from the pump to the laser has been cut and the switch is inserted inline with the hoses. Again it is connected to the "P G" pins and connected in series with the other safety switches.

Here is a link to the switch that I used.

Laser: was an A3 2.0w TTL L6/GRBL Z axis now 2'x3'
          OpenBuilds ACRO 510 w/ 2.0W TTL laser Cohesion Mini/Smoothie Z axis Homing switches
          K40 Cohesion Mini 60W LightObject LPS
          80W CO2 Red-Black 500x700

cool is simply a subjective state of mind
