So, The Jtech 2.8w laser on my machine decided to die, and I really didn't like the way the laser was mounted anyway.
Instead of going back to the jtech, I decided to take a chance on an 6w ebay laser.
Now this one uses just a simple power supply and has a built in controller. Just hook up the power and the pwm. I had to do some rewiring on the ox, but basically just added different ends to some wire I already had in the cable chains.
