I'm fairly new to the forum, but I wanted to share this article with anyone out there that is interested. I made a relatively low cost Water Chiller for my K40 CO2 Laser Cutter. The entire process is documented in this Instructables.com article: CO2 Laser Water Chiller
I also recently published another article on the Arduino based Water Flow Rate Monitor and Alarm that I built or my Laser Cutter That article is here: CO2 Laser Water Flow Monitor - Arduino Powered / Windows Controlled
If you like the articles please Vote for them.
I hope they are helpful!
