i have a laser with 3 tubes in it running off a qm2000. when i select my patterns, i can see the galvos movinig but there is no output from any of the tubes. i have tried formatting the computer and reinstalling the pangolin software with the 3.5 update and still no output. Also, i have tried the laser on another compter using the same card and software and the laser works fine so i know its not the laser at fault. is this a hardware or software problem? if it is a software problem, how can it be rectified?
