Yes, those external pots (well, the one that exists) is jittery when I turn it, but that affects both the X and Y axis. If I don't touch the beam size pot at all, it's OK. The issue really is with the X axis on all three of them. Very strange. As a side note, do you happen to know what those...

Mr. Briggs, I have your requested files attached There are some others, that I'm not comfortable posting. PM me with a current email. I would not power it up without a review of the other docs. This thing is a beast.

No, absolutly not with regards to the driver boards pots - and do not turn them. Sorry for the confusion. I was only referencing the big external pot on the back. If that pot is dirty it could be causing your x axis fluctuations. You have now indicated that the external pots are dirty, do you...

i use them exclusively with the ILDA inputs using Beyond. That's a good point about the pots, though. A thought I hadn't considered. They have a big external pot on the back to adjust the overall beam size, and that is dirty on all three of them (and one is flat out toast - any adjustment at...

"They were all manufactured in the summers of 2013 and 2014. So they're getting some age on them. All three of them from time to time will have the horizontal width of their projected images go wacky. After a few minutes, it usually clears up. And it seems to only be relating to the X axis, not...

Hey Steve, Many thanks for the information so far; much appreciated! All the best, Dan

The two sets of jumpers circled in the attached pics will go direct to the differential inputs, as they are used to reverse input polarity. I sent a request to a friend in Cali, if anyone has the manual he does. We shall see. Steve

All nearly of them use the same demodulator circuit for the photodiode currents Drive cable and Feedback cable have separate grounds and shield braid, From the attached you should be able to figure out the pinouts by reverse engineering the board. "AGC" is drive to the position sensor...

Heh. I like your thinking Adam! Unfortunately it’s for another project; 3mm aperture on this one though ;) I do have a plan to get some 30mm CA wagglers for next LEM though. *warn

please see attached More coming

More great info like I've come to expect from photonlexicon experts! Thank you! I actually heard back from X-Laser, and they confirmed that they can no longer get parts for the RGB MKV manufactured so long ago. Bummer. So, I'm about to take the sticker off (OH NO! It says it'll void my warranty...

lol, still have that pile of melles, i have the password, everything in those melles had something missing but one of them, a tec, a crystal, a diode. yay I got one of them firing up to a whole 50mw

Hypothetically speaking, would these amps be used to drive a set of galvos equipped with absolutely massive mirrors that would be appropriate for a certain CVL that we saw at UKLEM recently? Asking for a friend... *retardo Adam

Unfortunately, our little community here on PhotonLexicon has lost several people in the last few years. Ed Keefe, Mark Edgar, and Len Henzel all spring to mind, but I'm sure there are others I'm forgetting. Death is a strange thing. It's almost an abstract concept at first, because when you...

I think you'll find that working on the internals of a laser projector is not nearly as difficult of a task as it might seem. Honestly, in my experience, the hardest part is often related to things like adjusting the mounting heights of components, rather than any electrical concerns. I do...

When I heard the announcement my heart sank. Jayrob died too a few years back. Two good men

Great input. That's good to know about the voltage of the scanners. I've never opened up a laser projector before, so I'm rather intimidated by the idea. But like you mention, I like these little boxes so much, I'm willing to give it a shot. I'm sure I can handle a few basics. Hopefully I won't get...

Have you tried reaching out to X-Laser to see what they think? I don't know what it would cost to repair your units, but if the repair cost ends up being cost-prohibitive, you might ask them if they'd be willing to sell you a set of replacement scanners - assuming you'd be comfortable swapping them...

Good point, Rodney. I was very glad that Len was able to return to SELEM in 2023 so he could see the new venue and re-connect with everyone again, but it was clear that his health was declining. Len was a wonderful, kindhearted soul who was always ready and willing to help new people. His...

F is likely a Faraday Rotator (Strong Magnets) G KTP Assembly with oven controller PCB and polarization controlled folding assemblies B is flashlamp and rod.(NO KTP) That is an oscillator -amplifier (3 Flashlamps, 2 Rods) and I happen to recognize parts of it that are made or built under...

Peace to you guys too

Tariff barriers will cause mutual harm *DZ

I feel sorry for him too. Hope everything settles down soon.

Tariff policies are changing all the time, and customers have to recalculate their costs all the time

Hi Adam, yes tariffs are very crazy. All the products that should have been exported to the United States are now staying here. American customers are waiting for a “NEW” policy to pay less tariffs.

YES. I am wondering whether laser lights are "electronics". :confused:

We have several orders from the United States, and the customers have already paid. Now the customers are hesitating about when to ship to avoid high tariffs.
