K40 Laser Tube Extension to 50W 800mm
thingiverse
Made for K40 Mini when using longer tube, Nice screw thread lid prints at 101% for some thread clearance. Diameter matches the hole in the side panel of the machine which you remove. 200mm tall, so it might not fit in some machines. I used a textured paint after making 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 the Bridge pin IN to Pin 5V, then bridge the (Bridge) pin P to Pin G. Run two wires from the PSU to the board, a cable from L to Laser Fire on the board and another from Pin G to Laser GND. Job done. You can obviously run a lid switch between the P and G pins or wire a pot in the circuit using the IN and 5V bridge wires if you wish.
