Description

Anyone out there know how to fix laser concert machine. There's a round metal disk with holes in it and it spins around in front of the laser itself. The problem is that the disk is spinning in front of the laser and not the holes so the laser is getting blocked from shinning out the lense. Is there a pattern to it that makes the holes in the disk meet up with the laser itself? I'm good at setting them up and programming them but I've never had to fix one. I bought this new and it showed up this way and the place won't replace it so I'm stuck with it and I hope someone out there can help me out. Thanks....
