The recent Epilog Laser Challenge at Instructables. com got me thinking about building a low cost CNC laser. The engrave r 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. I want to approach this in a very serialized manner to prevent wasting excess money or time. The design should be very scalable to more powerful lasers. I will start with the lowest power laser as a proof of concept. I have built several successful CNC routers from scratch so I feel confident on the mechanics. The laser issues will all be new. There is a lot of mystery on the Chinese parts. I will try to fill in all I can along the way.
