Step 26: Power Supply Part 2
This tutorial is dated, if you are considering a CNC for your personal use, we would highly recommend purchasing a kit that is very stable from our wide range of machines available. This video will conclude the power supply circuit build. We left off at the capacitors and now we need to add the next capacitor. Two in all, and the capacitors will be connected in parallel. This will give me a relatively nice direct current (DC) voltage, which is our goal.

Step 25: Power Supply Part 1
This tutorial is dated, if you are considering a CNC for your personal use, we would highly recommend purchasing a kit that is very stable from our wide range of machines available. Now, we get to the fun part. We get to play with electricity. Well, it's probably not something you want to play with. In fact, be extremely careful. I'm going to provide information that, if not treated with care and respect, is lethal. For those that do not know what lethal means, here is a definition: Lethal = Death. In this case, it's not like quick painless death, but the slow-shocking-melting kind. I've touched 110 volts of house current before, and it's a weird but ugly feeling. Your body understands what alternating current (AC) really means.

How to Test a CO2 Laser Tube for Power
In this tutorial we'll explain the process for properly testing a CO2 laser tube for power. In this example we are testing a 40W CO2 laser tube and 40W power supply.
