Laser Quantum mpc6000 V3 control unit with Opus 660 solid state laser
Used as shown on the pictures. I did not have the original cable to connect the laser to the controller but found that an old zip drive cable worked and allowed the controller to recognize the attached laser. The laser, although recognized by the controller, does not enable or turn on. As such this is sold for parts. --- Item#626012LN4C ---
