My goals for this device were twofold: to allow me to *see* the coolant circulating thru my Laser Cutter, and observe its temperature in real time.
It was a bummer to discover that my retail air-assist nozzle didn’t fit, but in 30 minutes I made & installed something even better!
As my first really practical laser cutting project, I created an acrylic enclosure for a voltage regulator.
The K40 lasers are legendary for their shoddy quality and unreliable components, but as far as I can tell, those might be issues of the past! I’ve been getting excellent results—here’s what’s it took to get there.
