Its a 50W CO2 Laser - Nema 17 Steppers with controllers- 2020-V Extruded Alum - 3d Printed Parts - Power Supplies, and the 2nd Costly part... RDC6445G Controller.. (But could've used an arduino) I've started initial testing, but haven't gotten any further. I'd LOVE to repalce the Analog milliamp meter with a DIY VFD Tube solution.. I think it would look soooo cool... If anyone can help design that VFD Circuit for me. That would be AWESOME.
I haven't seen too many scratch-built laser cutter projects, would be interesting to see the design and build process.
