Re: K40 Laser Power supply "Power Adjust" in. The amplifier outputs are connected to the PWM comparator. As for pin 1, I would expect it to be connected to some kind of a feedback network. This would be compared to your reference input (the PWM or DC voltage). tl494.png (87.6 kB, 897x567 - viewed 95 times.)

Why You MUST Add A Water Flow Sensor Switch To A K40 Laser

With a water flow sensor switch it kills power to the laser firing circuit if no water flow is detected thus saving your precious CO2 laser tube and power supply. The switch in the flow sensor is in the normally open position. That means the circuit is BROKEN until water flows through the sensor and then the switch closes which ENERGIZES the ...

The wiring diagram you linked to isn’t complete; it doesn’t show (for example) the 24V from the LPS to the controller board to power the stepper motors. Here’s the theory: The LPS controls the laser, so everything that controls the laser including safety interlocks (case, water) connect directly to it.

Unbelievable K40 power supply earth grounding

Remember that the PSU is outputting DC. What you do want to check is that all the connections are sound, especially grounds. The grounding screw on the back is tied to ground on the mains input. Think the Chinese tell you to wire it to earth ground because over there they often don't have ground on the mains.

Upgrading a K40 Laser Cutter, Part 1: Control Board Upgrade

Unfortunately for us, the K40 laser power supply looks for a 0V signal to know when to turn the laser on. Rather than tweak the firmware to reverse the signal (GRBL isn’t exactly user-friendly), we are going to make a simple sinking logic inverter circuit. The laser firing signal itself is being held to 5V through an internal pull-up resistor.
