I’ve read dozens of posting with the same problem - they get closed after tech support responds by saying something is wrong, or the posting just seems to die out - without any hint of a solution.
The problem: The laser stopped firing midway through a file I’ve cut over a hundred times. The printhead moves as if everything is ok, just not firing. The temp in the room if fine, no amber light on the button, I’ve cleaned the lenses and checked the printhead cable (and gave it a shot of electrical contact cleaner), I’ve cleaned the contacts on the chassis that the printhead rides in. I cleaned and made sure the mirrors and lenses were all seated ( I installed a new lens in the printhead about 2 months ago) There are no blemishes on the mirrors or on the lens. I had previously put black electrical tape on the printhead cable where I started to see slight wear spots from the cable rubbing as the printhead moves back and forth, that was months ago.
I see from the various postings that they always want you to “Print the gift of good measure”, so I did that, many attempts. The printhead moves as if all is working, but no laser. One time when it was “printing” the gift I got a wide , unfocused white light from the printhead (about 2" across - about the same light as a flashlight) and the red focus beam turned on. The printhead continued moving as if it was engraving) - other than that one time, all has been dark. The laser tube does not have the tell-tale little streak of light that occurs as the laser fires.
It’s in the same room that it’s been working in for the past 2 years, so not environmental issue - nothing else has changed.
BTW: It’s a Pro model that’s a little over 2 years old.
Any solutions beyond the obvious questions that will be asked?
A ticket has been opened with support, but it’s Saturday afternoon and I don’t expect to hear from them until at least Monday at which time I expect to hear “there is a problem with your machine that cannot be solved remotely”.
