Full Spectrum 4th Generation Series 40w MLE-40 Hobby Laser

I bought an old Full Spectrum 4th Gen from a friend and it never worked quite right, so I replaced the stock controller board with a Cohesion3D Mini (this was in 2018 before the LaserBoard came out.) I added LightBurn to the mix and it’s been a solid machine! I wrote a lengthy blog post about the upgrade process: http://rasterweb.net/raster/2018/05/04/cohesion3d-mini-full-spectrum-laser/
