You may know most of this already, I am just releasing a summary for boosted holiday views  😏

All the lasers: Argon Ion, 45W Fiber Coupled, CO2, Erbium Doped

Even if it’s just a summary, definitively worth watching for added visual effects and additional annotations! But hmm, so you are still not that much excited about my suggestion to go for a "direct drive" solution for the CO2 laser? Think about the possibilities together with the upcoming tool changer system from E3D! :P And by the way, for the part with acrylic sheet dedusting: Did you hear about anti-static guns? I had used one yesterday for the tray of a cheap precision scale that influenced the reading without touching!

It would be a delight to mount the tube on the head, and I think we have plenty of machine power to drive it reasonably fast. But it would be a huge machine with kilograms of 3d printed parts for stable mounting ... maybe a hollow waveguide-like fiber instead? I only know about those HV guns for ESD testing, how would the opposite work?

We use air guns with a built-in radioactive source to remove dust from the delicate optics in some of the stuff we make where I work. It just goes on the end of a compressed air line as usual, except the air goes past a bit of some radioactive material which ionizes the air to keep it from generating static electricity on the optical elements and attracting dust. They apparently also used to have soldering station air circulators with radioactive ionizers built in, as well as a heating coil to offset the cooling effect of the air flow. They've since pulled out the sources and we just use the heaters to warm our feet.

Just a suggestion for your new lasers. Please verify what type of polishing and format the sma connector has. There are many variations. Take a look at this website <a href="http://www.thefoa.org/tech/connID.htm." rel="nofollow noopener" target="_blank">http://www.thefoa.org/tech/connID.htm.</a> I personally would check with the manufacturers documentation and if it's not apparent call them to see what specs they used so you can get the maximum output without worry or problems. But wunderbar video.

Thank you, great link! I've already asked Jenoptik but they are of course too good reply to individuals. I have little doubt about what I need precisely tho. Only thing that's not entirely clear is: Can I use a slightly larger core diameter than is asked for?

Wow that sounds awesome, both the air guns and the soldering fume extractors :) <a href="https://imgur.com/a/u1WwLMh" rel="nofollow noopener" target="_blank">https://imgur.com/a/u1WwLMh</a> I'm occasionally using my reflow hot plate for feet warming purposes

Yes, you can but it will probably cause losses since the surfaces might have different characteristics. Please give me the Part Number of the Jenoptik device and any other information (version etc.) and I will try to obtain the information for you. Here is a website which discusses the SMA fiber connectors and you'll understand what I am referring to. <a href="https://focenter.com/what-is-an-sma-connector-and-why-do-we-care/" rel="nofollow noopener" target="_blank">https://focenter.com/what-is-an-sma-connector-and-why-do-we-care/</a>

Oh, thank you very much! All I know is on these labels: <a href="https://imgur.com/a/oJgNTj6" rel="nofollow noopener" target="_blank">https://imgur.com/a/oJgNTj6</a> and a datasheet from the internet <a href="https://www.jenoptik.com/-/media/websitedocuments/laser/diode-laser-modules/jold-45-cpxf-1l.pdf" rel="nofollow noopener" target="_blank">https://www.jenoptik.com/-/media/websitedocuments/laser/diode-laser-modules/jold-45-cpxf-1l.pdf</a>

Per the Spec's on the module: Fiber Core Diameter, Numerical Aperture 400 μm, NA 0.22; free standing fiber inside F-SMA 905 towards the module Fiber Connector F-SMA 905. I am not sure how you are preparing the output of the module.

Have you retested the TS100 w/custom fw and TS80? I think the test results seemed a bit off (or oof), if you ever gonna do a followup to that vid, it would be nice if u used the same tip for both (preferably the chisel one). I need a new iron for THT stuff (max snap in caps), some TO-3PL (big TO220) and 14 gauge wire and smaller soldering. Do u think the TS80 @ 24W (12V 2A) would do the job well?

Hey, what driver are you using for the cooling fan in the Argon laser? Thanks.

marcoreps

oh just a regular hobby BLDC driver (like in quadcopters and RC cars) and a servo tester to put out PWM based on potentiometer position
