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.
Alden G's CNC Machine and Narrative
I have seen many builds based on the step-by-step instructions on this site, but when I see the the DIY community start to mix the ideas of one CNC machine with another, I get really excited. To take a machine and introduce concepts from another machine, like timing belt mechanics, is clever and welcome. Alden also is very creative with where he positions the drivers.
Cutting/Milling Metal with the blackToe CNC Machine
