How to hook up safety switches to the laser power supply
« on: November 10, 2017, 01:20:25 PM »

What I am going to show here is how to disable the laser from firing. This does not stop the head from moving around because we are going to make the connection on the laser power supply - not the controller.

The picture below show's a picture of my power supply. Notice the connector that is marked "P G". These two pins need to be connected together to enable the laser. On some power supplies they are marked P+ and P-. So how I have used it is to hook up a micro switch on the cover, and emergency stop button, and the water flow switch. I have all the switches wired is series so if any on of them opens the laser will no longer fire. I will show each component in separate posts but the important part here is they are all in series.

The picture is showing the power supply, and I am using the M2 controller that came with the machine.
