Need Help Troubleshooting a (1999 ULS M30 / M-300) Laser not working

[Mike Null]

Whenever I've had a tube/power issue, including my old ULS 1998 model the machine worked but the engraving or cutting was so weak it was nearly invisible.

I would call tech support for their suggestions; particularly whether you can use that version of Windows.
Check your printer port connection.
Replace the pc to laser cable.
Confirm the interlocks are working.

I'm thinking your machine is a twin the old New Hermes "Optima" laser I used to have, it was a re-branded Universal, and your display is exactly the same as it was--

Concur on the magnetic interlocks maybe being the problem.. I used to tape round magnets to the frame opposite the sensors so I could run the thing with the door open--

Another thing it MIGHT be, could be the red LED pointer-light is "on" but not working-? Do you know if it works? I don't remember how it turned on, been a long time -
If not, experiment with that too, if it does work, then that won't be the problem, if it doesn't, maybe try cycling the "on" button/switch...
--edit, just found a pic of the old thing, which is also a 1999 machine-- FWIW, best I recollect, the magnetic interlocks are somewhere just below the lower left/right corners of the cover...
