I'm looking at getting into this hobby. I saw a flux delta 3d printer with it's weak 20mW engraver and realized I just want a laser cutter, not a 3d printer. I didn't know this thread existed when I first posted in the CNC and 3d printer threads. Last year I bought a dangerous Chinese product: an electric unicycle, and have been meaning on posting a megathread about that piece of poo poo, so I fully expect that this thing will not work well. Thanks to the OP I already know how much of an overhaul to expect. I want to build project boxes for small electronics - thank you arduino and small electronics threads, but I dislike dremel's, power tools, and hand cutting acrylic. Can anyone give me a good Taobao link to make a purchase? I'm in Taiwan. Looks like there are a lot with air assist heads already installed. https://world.taobao.com/item/521183792072.htm https://world.taobao.com/item/41165405439.htm

Well poo poo, I had an electrical outlet fixed today in my apartment and found out all the outlets in my building are not grounded. Plus, the guy who wired the place warned me to only use hair dryers on 2 specific outlets. He wasn't speaking English... I assume the wire gauge is too light for the current draw a hair dryer can pull. The power box has the following circuit breakers: double 50 AMP (feed?), double 30 AMP (Hot Water heater), double 20 AMP (Air Conditionaer), and 2 single 20 AMP circuits (lights, outlets). I saw the information in the first post about the loud BANGs of current arcing to the box. This sounds super unsafe without a ground.

He was working on a live circuit, so his advice is a little suspect. Regardless I'm quite certain there's no ground. Whenever my air conditioner goes into a heavy duty cycle, my electronics go haywire. I haven't seen any copper anywhere. Regardless, I was warned that Taiwan may levy high taxes on co2 lasers. I found a k40 with a huge markup on a local website. I am going to see if I can find more 5.5 watt diode laser information. I found some information about a guy who manually raised his cutting bed and used multiple passes to cut acrylic. I just really want a small box fabrication station I may explore the 5.5 watt diode laser route.So far I am pretty discouraged. politicorific fucked around with this message at 05:35 on May 21, 2016 |

Okay dumb question, the white wire in the upper left would appear to be the ground to my apartment's electrical box, but it isn't hooked up to any of my outlets. Is there a safe way to test to see if this really a ground?  http://i.imgur.com/h6SuaYL.jpg http://www.doityourself.com/stry/how-to-test-for-ground If this is the ground, I'm wondering what the best way to use it would be, attach directly here, or hope I can fish it through the wall to an existing outlet without doing any damage.
