Protect all the eyeballs!
I got excited when I saw that you had posted. I like the content you put up so it's fun when something new pops up from you. Also I certainly may be wrong but I know that to create laminar flow for liquid, a cluster of long channels (like a bunch of drinking straws) is needed. So I suspect the problem with the one you build is that the honeycomb is much too shallow. Thanks for the testing and info! :)
I love your videos, you've got a great way of walking through problems and explaining how things work. Everything you've posted is explained so simply but so easy to follow, lots of fun to watch!
I’m with you 100% on a full enclosure. To be extra careful you can make pet laser goggles! What every pet loving maker needs.
😎 although I'm not sure every maker loved pet would love wearing goggles 🤣
Amy, please do more videos, you are definitely brilliant! Thanks for the link to N E R V O U S system blog as well xxx
Thanks so much for your sharing, Amy! You're so amazing and your video is so informative and helpful!! Love it so much!!! Wish you all the best🥰🥰🥰
You're so talented Amy!
Thanks great info , especially the safety and support software. It’s amazing how inexpensive these are.
Great video, love your content and attention to detail.
These small integrated semiconductor laser modules getting cheaper and more powerful. One could probably build a laser with a huge cut area, like 1m x 2m or even bigger, to cut, let's say fabric or cardboard templates, etc. Thanks for the review!
My guess would be that the "laminar flow" nozzle has a higher loss coefficient than the other nozzles, so the flow velocity is reduced and hence it is less effective. That would also be the same reason why the pump works better than the fan. The small diameter nozzle has a high loss factor, so you need a lot of pressure to achieve higher flow velocities.
You can easily compare the loss factors if you print an adapter for a water bottle and measure the time it takes to drain the bottle through the nozzle.
Testing is good, we like testing. Carry on, madame!
haha, thank you!
Great video. Super useful information. Well documented. Been considering one of these... Mahalo for sharing! : )
Mahalo!
Great video! I knew (from watching Osmans channel) why the airflow is important, but I never would have put any thought into how much flow or laminar/turbulent flow.
thank you!
@@AmyMakesStuff yep! I love your channel btw.
Great info!
Great video! I was wondering how I could use an aquarium pump as air assist.
Hear, hear for everyone observing safety measures around lasers!
As the old lab signs say, "Do Not Stare into Laser with Remaining Eye!"
Omg i have to make that sign 😂
I just noticed that Comgrow sell a $65 soft enclosure for people who don't want to build their own. I personally prefer a hard enclosure but YMMV.
Ya, hard enclosure is better. I don’t even know that fume extraction would work with a soft enclosure.
thanks for the video and may the protector of eyeballs be with you.
😎💪
nice.
hmm, I expected a lot more from the laminar ones! interesting. Maybe the surface is too rough? I can see some stringing inside the laminar flow part. I also wonder what the influence of the curve of the nozzle is after it passes through the filter (when it condenses the airflow). Anyway (Amyway lol), good to know that pressure is more important than laminar flow!
Amy, you're generous with your insights and sharing knowledge and it really is appreciated! I'm an audio engineer / editor (and casual maker), I'd be more than happy to help out with some sound editing / mixing on your vids if you're ever wanting any assistance with that :)
Oh man, help would be awesome. Even just to get a better idea of what I should be doing. Right now I edit everything in iMovie. I feel like I could do better on just the raw audio recording. Shoot me an email if you’re up for chatting more?? amymakesstuff.info@gmail
@@AmyMakesStuff Sent you an email :)
Great information - I've just bought the same laser module (and a 3D printer), and would like to make the air nozzle. Have you published an STL file of the nozzle?
Not yet! Good idea, will do that.
@@AmyMakesStuff Thank you !!!
Are these nozzles being sold anywhere? I don't have a 3D printer to make myself.
Btw while lightburn is great and worth the price they did double the price for the 1.0 release. EDIT: I remembered wrong and it was a 50% increase, and the price given in the video was the newer price.
😯I didn’t know that!!
@@AmyMakesStuff This is incorrect. It used to be $40 for GCode and $80 for DSP. We increased the prices by 50%, not 200%, with the v1.0 release and they are now $60 (as you correctly stated in the video) and $120.
We strive to keep the software as affordable as possible, especially for users of GCode based machines which are typically far less expensive than a large CO2 laser.

Thanks for the shoutout of LightBurn and keep up the awesome work! Your videos are always great.
@@AdamHaile Thank you for the clarification!
@@AdamHaile Ah sorry for my wrong information, must have remembered wrong. Still recommend the software all the time though, absolutely my favorite one to control lasers!
Regarding the "double line"... I have no strong basis for this guess, but if it's toward the end of the "print" job, could it possibly be a buffer-full and/or handshake issue where error detection/correction repeats a "line" of G code because it was thought to be lost in transfer? If so related to comms, maybe some settings in Lightburn could help?
Hopefully I won't waste your time on this, since I have ZERO knowledge of Lightburn.
Hmm, you’re right that it’s happening towards the end of the job. Not always the same place, but toward the end.
Have you made the files available for the 3D printed nozzles?
yes I did, sorry for the delay. Added a link in the video description.
Hello, the 3D print can be in PLA or it must be in ABS ?
PLA will probably work for a while, but just not last as long since the heat from cutting might damage it.
@@AmyMakesStuff Thank you for your answer ! Have a nice day :-)
:*
just FYI, for the first 30s of the video, the audio is only on the right channel
oh, did not know that, thanks!
Maybe you could use a Schlieren system to find the parameters that give the best laminar flow through the nozzle: czcams.com/video/4tgOyU34D44/video.html
Whaaaa that’s so cool!!!
That would be more fun than doing hours of simulations, downside being that it would be physical prototyping.
Haha, that’s usually not a downside for me :)
Fair enough.
Laser fumes are horrible, don't waste money on an un-enclosed machine, you will find the fumes so disagreeable you wont want to use it. Not to mention the laser eye safety issue.
