That cheap Chinese 40w laser cutter I bought - it died within a month of operation
I wrote about the laser cutter that I recently bought from eBay. It was the cheap Chinese make with a 40W CO2 laser tube. Overall it was not a bad machine, but within a month of using it, and probably only making between 10-20 actual cuts, the machine broke, but it wasn't the laser tube that let it down.

A clear acrylic case for the DSO138 digital oscilloscope
The DSO138 digital oscilloscope that I've put together recently is a nice kit but it lacks a case and it's always nice to have an LCD display protected. I decided to do something about that and make an acrylic case on my laser cutter, before it stopped working anyway.

Cutting and Engraving with a 40W CO2 Chinese Laser Cutter
I had my CO2 Laser Cutter for a couple of weeks now and in case you missed it, I've written up my initial experience with it over a three part article (part 1, part 2, part 3). I've had a bit of spare time to play around with it a little more, did some cutting and engraving on various materials and at various settings. These are my findings.

This is the third part of this article, in case you missed them, check out part 1 and part2 before you read on. Those parts run through the unboxing and setup of the machine and also mention some of its faults. This part focuses on connectivity and software.

If you've missed the first part of this article, you can find it here. This part covers some of the faults I found with the laser cutter and how I set the whole machine up.

So I bought a cheap Chinese 40W CO2 Laser Cutter and it's actually OK (Part 1)
I've been tossing up the idea of either getting a new 3D Printer or a Laser Cutter and then I came across Flux3D which could do both to some extent. After nurturing the idea for about a month I decided that I didn't want to mess around with another 3D Printer until they were easier to use so went for the Laser Cutter. After a number of quotes (some going into tens of thousands of dollars) I hit up eBay and found that for just $550 AUD I could buy a desktop sized laser cutter. I was sceptical, but I went for it. Read on for my experience.
