    That's why I use a dslr and switch to manual focus. Phones have the worst time with lasers. Awesome show! I really like the beam brush!

    Mike's camera apparently kept going in and out of focus. I'm not sure what the heck was going on here ;-) https://youtu.be/Z1Cne0R7AGg

    ... if for detail -- my first FDM setup used a nozzle with 0,8mm bore ... the first DLP-resin printer was capable of 0,01mm in XY and Z :cool: But for "serious" microfabrication (laser-ablating, removing 200nm material per pulse) I've used an excimer laser with sub-micrometer resolution >:) ...

    I noticed that, as well. I started a thread a while back comparing greens https://www.photonlexicon.com/forums/showthread.php/20708-Green-lines-are-fascinating. Cameras really do a number on color.

    If your running single wavelengths through each telescope your looking for "Aspheric" or " Best Form" lenses to go long distances. Otherwise normal spherical is fine. If you can find an old, old, Melles G catalog the pages on Collimator /Telescope design are worth reading. As achromats are well...

    it really sucks how it looks on camera though... 532nm looks more yellow than 568nm and it makes me sad, haha.

    I have a Taz 6, a Taz Mini, and a Moai SLA printer. The most complex work I have done on mine is printing the parts for my fogscreen. Sadly, I never use my SLA printer. Too messy and I really don't need that kind of detail. I only got it because I got in on the Kickstarter pretty early and got...

    I'm not sure what that means for a collimated beam. I'd guess an aspheric lens would perform better than spherical, but achromatic seems unnecessary for an monochromatic light source.

    I'm working on a simple beam expander for some Taipan lasers. One negative lens and one positive lens with a mechanism to adjust the distance between them. Commercial units all seem to use achromatic lenses. Is there any advantage to using an achromat over a simple (i.e. cheap) spherical lens when...

    You all have some amazing machines. I started with the Printrbot Kickstarter machine and after several upgrades that were mostly toys, I now have a Prusa MK3S which I consider a proper tool. It's in another room controlled by a Raspberry Pi running Octoprint. 99.5% of the time I throw jobs at it...

    To add a little more about the laser 2 pin connectors on the ILDA board. The positives do "ohm back correctly to their respective R, G, B + pins on the ILDA connector. The Grounds for each seem to have commonalities amongst a few pins (not sure if this is as intended). This was done without the...

    That makes sense, not sure what the 4 pin wire is, cannot see any writing. The post I linked to has almost an identical board. Just need to know how he set everything up lol. Here is the rest of the diagram, wasnt sure how much was needed but I supposed the whole picture is good.

    Your diagram only shows part of the system. It's possible that the galvo driver is providing a +/- 15V supply to the rest of the components.

    jdavis7765 replied to a thread Galvo/Amp Upgrade in Modifications
    Looks like I may be pretty stuck. The lasers will only light up, ILDA or SD, when the existing amp and galvos are plugged in. I know this laser has a beam safety mechanism when the laser scan angle is below a certain degree. This may be preventing the lasers from firing up. So I suppose my next...

    aberry replied to a thread Galvo/Amp Upgrade in Modifications
    From the back of the ILDA PCB it looks like there's circuitry on the front, so it depends on what functionality that board contains. Your minimal effort solution to get the new galvos working is probably to leave all of the existing electronics in place and just connect the new galvos exactly how...
