My VLS 6.60 will sometimes shut down immediately after I power it up - after a couple of tries, it'll turn on.
I've noticed that it would shut down when I close the lid. Thinking that a cable was getting jostled, I closed it very, very slowly several times. The laser still shut down.
I'm suspecting that perhaps I have a floating ground or something. I've had the same symptom even when I shut the front of the laser.
I'm thinking that it's the interlock circuit causing funky behavior (thus the suspect ground)
Any thoughts on this? This is a used laser that I just purchased, so I haven't checked with Universal... yet.
