DIY 40W laser cutter

Bdring of built this 40W laser engraver cutter from scratch. The goal is to make a laser cutter for under $1000. Excellent work!

The recent Epilog Laser Challenge at got me thinking about building a low cost CNC laser. The engraver they had as the prize had a list price of about $8,000. The income tax on that would be quite a lot. I thought a larger more powerful machine could easily be built for less than the amount you would have to pay for the tax. The Epilog Zing 16 is 30W with an area of 16″ x 20″. Try to beat that for less than $1,000. I understand that a huge part of what you get from Epilog is software, safety, support and a guarantee, so it is not a really fair challenge.
