Beams vibrating?

Note also that the galvos in the Neo-Laser lasers are not very good and do tend to break after a while. I replaced mine with ScanPro ones, got a good performance increase, and now I have Cambridge scanners :-)

If you use seperate outlets make sure you keep all equipment that connects together on the same outlet or to isolate the grounds to avoid a ground loop.

What is a good site to buy those? And I would have no idea how to install them lol is it easy and recommendations about going through the changing process?

I bought my ScanPros from the excellent lasershowparts.com. They hang out on here, or at least Dave does. The advantage of the Scanpro set with the NLSP-series projectors is that the galvo amplifier cards have the same connectors as the Neo-Laser parts do, so you can just swap in amps and galvos without having to rewire anything.

Which model would be best for me? I'm
nervous about this lol I don't want to sscrew up my laser so it won't work and I have no one around to help me. I'm in America the website seems to be from Australia. Same prices? Do they ship worldwide?

Well, if your existing galvos are working fine, I'd suggest leaving them alone... taking your projector apart will void its warranty. Changing the galvos should not, however, affect the variance on the projector, so you're okay by the law.

As for your other points:

- whereabouts are you? We have members all over. I bet someone will be nearby to help you out.

- The prices on the site are in Australian dollars. An Australian dollar is worth about 80 US cents.

- They ship worldwide, it just takes a little while, about a week and a half.

The galvo system consists of:

- a power supply (you can keep the one that's already in the projector)
- two galvos, mounted to a...
- metal block that holds them in place and keeps them cool
- two cables going from the galvos to...
- two printed circuit cards that amplify the signals from...
- two cables carrying signals to...
- a controller card (again, you can keep the one you already have)

All of this is attached to the bottom of the projector.

When I did the swap it was as simple as:

- turn off the projector (!)
- open the case
- free the wiring from the 12232482 zip ties holding it down
- unplug the galvo amplifier boards from the signal cables that drive them
- loosen the two hex screws that hold the galvos in their block
- carefully slide the galvos out
- remove the plastic caps from the new galvos and put them on the old ones
- put the old galvos somewhere safe, and put the new galvos in the block
- make sure you've put the X-galvo in the position where it tilts left to right, and the Y-galvo in the position where it tilts top to bottom
- gently tighten the screws holding the galvos in place
- remove the screws mounting the old amplifier boards from the baseplate
- remove the old amplifier boards and cables that go to the old galvos
- install the new amplifier boards and cables in the spot you've just vacated
- make sure you've plugged the X-galvo into the X-amplifier (don't cross them over, they're individually tuned)
- plug the (original) signal cables from the new amplifiers
- install all screws or clips on all the connectors! Ziptie or tape down the wires so they can't float around when you move the projector.
- use tape to defeat the microswitches that sense that the chassis is open
- turn on the projector at low power and adjust the positions of the galvos so that the beam is properly centred on the mirrors, edges aren't cut off, etc., then tighten the screws up (but don't go crazy- just normal-tight, not super-tight)
- switch the projector off again
- remove tape and reassemble case

It sounds a lot more involved than it really is. Which model is your projector?

I live in Kansas city Kansas U.S. The laser is neo-laser disco 250mw rbg. It's long and silver. The knobs sit on top towards the back.
I forgot the exact numbers I'm not at home right now. It's about a year and half old so the one year warrenty has already expired
