I finally got a laser cutter! The model I have is the FSA 40W CO2 Hobby Laser 5th gen. The cutting area is 12" x 20". I don't have it set up yet but it looks to be a pretty nice unit. I'm planning on building my own chiller unit for it (more on that later) and I still need to hook up an exhaust fan. I'm completely new to the world of laser cutters so if anyone has any tips or tricks it would be greatly appreciated!
I forgot to update this thread! So here's my take on this machine-
First, it is by far one of the coolest tools I've ever used. Very easy to set up and run. You design your parts in a program like Inkscape and then hit "print" which exports the file to the laser cutter Retinaengrave program. Then you tell it to make a vector cut and set your speed and power settings. Then it cuts your parts like magic! Three ply 1/8" thick plywood sheet cuts in a single pass like a dream with the speed set at 45% and power at 90%. Six ply aircraft grade plywood is much more difficult to cut and takes multiple passes at a lower power setting to avoid burning.
The only downsides to this machine are the smell of cutting and the loud exhaust fan and air pump. It's definitely not something I could use while the kids are sleeping unless I had it out in the garage. The laser is also pretty big and takes up a fair bit of space.
