I am one of those crazy DIY laser nuts that started from the Lasersaur google groups days before DIY lasers where the popular thing to do.
Fast forward 6+years I have now built several machines for myself and others with a great interest in eventually selling my own custom built gantry and nozzle designs.
I also created the facebook group “The Laser Guild” for the DIY machine builders, in attempt to have a well versed and centralized knowledge base for those who have plans or already have home built units.
We have well over 1K members within a few months and growing!
