K40 Laser Tube Extension to 50W 800mm
thingiverse
Made for K40 Mini when using longer tube, Nice screw thread lid, print the lid at 101% for some thread clearance. Diameter matches the hole in the side panel of the machine which you can remove. 200mm tall, so might not fit in some machines. I used a textured paint after it was made to match the machine. We also fitted the 50W Cloudray Tube along with MYJG PSU. The wiring on the MYJG 50W Cloudray PSU, to the Cohesion3D Board is very simple. On the PSU itself Connect (Bridge) pin IN to pin 5V, then connect (Bridge) pin P to Pin G, then all you need to do is connect two wires from the PSU to the board. Pin G run a cable to Laser GND, also run a cable from L to the Laser Fire on the board. Job Done. You can obviously if you wish run a lid switch between the P and G pins, or wire a pot in the circuit using the IN and 5V bridge wires, but bridging 5v to IN just maxes this out so you can control power from the cohesion3D board.
