This week, we're going to be looking at replacing the water flow switch on a 50-watt laser engraver I recently purchased, with a water flow sensor I purchased on Amazon. If the water flow switch on your co2 laser engraving machine fails, it will prevent your laser cutter from firing. This laser cutting machine is similar to the popular k40 laser cutter and other Chinese laser engravers, so the setup process should be similar on most of them.
