Please visit www.DIY3DTech.com for more information on this and many other projects! As in this episode we will be kicking off a short series to design and build a new set of laser tube alignment hangers for the K40 eBay Chinese CO2 Laser. As it has become clear this added level of “alignment” is required in order deliver the full power the 40watt beam to the increased bed area. We started the design with a Thingiverse build for a 50watt version and quickly found many modifications where need to make it work the K40. To do this we are useing Open SCAD and making it at least semi-parametric to allow easy future change.
