I've done testing with a spectrometer to check how effective those junk green glasses are. They are absolute junk and do not stop anything in the 200-600nm wavelength. Considering those diodes are all in the 400nm - 450nm range. They are 100% worthless. Spend the money and get a real set of safety glasses. Opt Laser sells glasses for around $50 the are OD7+ all through the 400nm range.
I'm assuming it depends on the quality of the green glasses? I haven't done any tests on them myself but my boss' old lab had them around for when working on Raman spectrometers so I assume he had the relevant safety kit. (I used to work in the physics department of a university)
I actually shone my laser in a sacrificial pair of those glasses. The glasses melted and the paper behind was fine. It's still glaringly bright and looking at the focal point will still feel uncomfortable. But I don't think they will fail at protecting you from a frontal hit
"I'm gonna keep taking advantage of these emails as long as they show up" king. this is the chaotic good opposite to AvE's lawful good not-taking-sponsorships-ever.
To be fair, not really a sponsorship as they aren’t paying him. A compensated review would be more accurate. We send you something for free to review and you keep it (also they didn’t seem to be one of those companies that pushes for a good review - so already better than many other companies), and no offer of “if we we like your review we’ll do more business in the future. All in all, this seems like the most fair and honest review method. We’ll send you something with no demands and no promises and no comment on your final product and no incentives.
Just for your safety, make sure you can barely see the dot from the laser with your goggles on. The goggles being green is somewhat worrying for me as goggles for 445nm lasers are generally orange. Over a watt of laser power is definitely enough to cause eye damage even from looking at the dot, and God forbid a reflection so stay safe and (as styropyro says) happy lasing
Brainiac75 has some good videos on laser eye protection where he checks the actual wavelength of chinese lasers vs published. I'm going to have to check out styropro now too.
I was going to point this out. I got a 30W Fiber laser, the goggles that came with it seem to be just green tinted cheap safety goggles. They DON'T BLOCK THE WAVELENGTH OF THE LASER THEY SHIPPED WITH!. Neither do they really block anything else very well.
@@ObservationofLimits Well, except most common everyday pigments do not filter out infrared (because most pigments for transparent plastic is made for light filters, you WANT them to pass IR so they don't get heated up by halogen lights). These goggles also passed a good amount of near UV light.
It's a cool machine. Especially for the price point. But if you give it away, give away a proper set of laser safety glasses with it. The glasses that are delivered with those things are often low end and worst case, sometimes don't work at all.
Forgive me for being a dummy, but why do you need them when the laser is facing down a few inches from the target? Does the light that reflects out damage your eyes?
If he's building a fume hood around it, he could just either make the hood opaque or get a tint in the appropriate spectrum and make the entire fume hood also a safety shield for the laser light
Fun to see what's actually on the other side of those emails. Great video, my friend. I've gotten plenty of those same emails and, like you, I recently said "sure, why not?" to a laser. I haven't gotten it yet, but I suspect it'll be the same one you got.
I think they send to all UA-camrs and then after we respond, they make a pick of who's channel is better. I already said yes to a bunch of mails. No laser came yet.
Fun video, but I'll join the choir here and echo that you really need to get some proper safety glasses rated and certified for the laser wavelength (at minimum). Even a glancing reflection can blind with a laser like that, much less a 15W version. If that one is going into a domestic setting I'd recommend a full laser-safe lid with safety interlock (requirement for most makerspaces, schools, and work places for obvious reasons). It's best to be extra careful with one-strike-you're-out machines like that.
That does look like fun! I'd like to echo what others have said: Get a proper pair of laser glasses if you wish to keep your eyes working. I would never have to worry about my cat around this thing: She's too lazy to bother chasing lasers. Wish I was kidding.
This is legitimately the only tool review I've ever watched because I find them boring and pointless. Robert, your presentation style is amazing and I love everything you do.
Robert, you do a great job as a tool review channel! Like a more handy Ed Bolian, I could listen to you talk about just about anything. I say keep taking advantage of these freebies if you enjoy it. Great job!
Yea I like that he jokes around but gives a semi-serious review. Many other reviewers tend to have no emotion and also end up focusing on how bad or good something is. “I know it can’t work on clear acrylic but what the hell, I tried anyways” 10/10 review method.
i found your channel like 1 month ago and im having a blast, ur the first guy that makes me laugh out loud when im viewing youtube. there is like no other. keep up the good work.
I have the non "pro" laser master 2 20w and it is a rather capable machine. Adding an "air assist" is prob the best thing you can do for yourself with any of the diode style engravers. It *greatly* improves efficiency in both cutting and engraving.
honestly, I loved this content, give reviews to random stuff that you think might be useful for yourself. plus its also a win-win assuming the company doesn't send you a heap of garbage, and if they do send you a heap of garbage, Man will it be funny to watch you make fun of it
I just stumbled onto this video, having not seen your work before... you had me chuckling all the way. It's 1.30am, my dogs keep looking at me like I've offended their ancestors. Great video mate.
You are not a tool review channel, but you are honest and funny, and that made this video awesome. I’m gonna wait for the next laser review video, I know it’s gonna be as funny and entertaining as this one
Never seen your videos. The algorithm suggested it for me and man, this video is hilarious. I am actually waiting on this exact machine at the moment. I had the non pro version and though it is low power, it is great for portable use.
A laser engraver can be very useful for layout lines. You take the thick material, engrave the parts on it and cut them out on a bandsaw. It's much more convenient than printing paper templates.
I have a similar laser and have used it for making templates for use with a router and flush trim bit. Once you get the quirks of the cheap laser figured out you can make very precise templates.
Love these videos. Wouldn't mind seeing more reviews like this, even on another laser engraver. Maybe a video about your 3D printer. I have one too but haven't had time to use it in a while.
I've had great success using an indoor hydroponic ventilation fan with my CCL (Cheap Chinese Laser)... they have modest "organic filtration" in the form of a carbon filter (gets rid of dank smells when growing stuff in manure). But they are easy to acquire online, and they have good remote turn-on capabilities.
I'm not going to join the 'proper-set-of-laser-safety-glasses' quire, as your safety, is your concern. I'm just gonna say, now I wanna laser engraver. Oh and, Cool Vid as always. Love your editing style.
Found your channel yesterday and now I'm all caught up. Great videos, keep up the good work! (BTW, should have painted the walls before installing the dust collection ;D)
Before you buy one for yourself, you might consider just getting one of those import K40's. They are actually cheaper than the device on your table, and are actual 40w C02 laser tubes. The downside is that the cutting area is smaller (if you make a better table, the effective area is 8x12. I've had mine for about a year and have since done a bunch of small upgrades, but at some point my plan is to make a new enclosure and transplant the guts, so that I can have a 2' x 4' cutting area, and at that point I will switch to linear rails, but the current methods is the same as this engraver, v rollers on extrusion.
Loved it, I have been a long time subscriber and always find your video's entertaining and very educational.. I also love how you look at things outside the box.. Keep doing what your doing.. Also, Never turn down free, even if it's junk, it was free and only takes a few moments of your time, that sadly you can not get back.. I for one would love to see you doing some tool reviews, I know you will always give a very honest opinion of said item... I await the next video.. Be blessed....... 😎😎😎😎😎 Also, you can take some of the free tools they send you and do a give-away to your followers, just an idea..
You could start a second channel just for reviewing these products if you don't want to clutter your main channel with these videos. I'd love to see you review the weirdest chinesium contraptions you can get your hands on.
3:58...Go Missouri! Thanks, I watched your video and was moved to get my diode laser going over the weekend. Mine is a Nextwave Moray which is a 7Watt, fully enclosed unit which as you say retails for $1500 (I got mine refurbished). The enclosure helps with smoke evacuation and I feel a bit safer given that I have kids in their tweens.
You should look at the A5 pro with the 20watt laser. I've tinkered with one for a bit and was generally impressed. The laser point has a much smaller focal point and comes standard with the Z axis adjustment rod. It even had a stepper motor on the Z axis so you can bump it around in the software for the final fine adjustment. I'm sure there could even be a way to automate that process.
Lasers are very fun to use. I can use a 80W CO² laser in our hackerspace in Bamberg, Germany. Just yesterday I used it to cut a gasket for my Fiat 126p carburetor out of Elring EWP 210 gasket paper.
The pro is the 3rd version and best so far. I have the lasermaster 2. It has been great and the best Christmas gift I've ever gotten. I wish I had thempro version but hey I'm good with the one I got... it didn't cost me a penny.
FYI...i have a Ortur Laser Master 2and have been having a great time with it. etches glassware with a little work. Works on canvas very well, black slate, acrylic. It rocks You do need an enclosure, for eye safety and fumes. I use a small grow tent, works great. Engraving at 100% power is not good for the life of the laser. I engrave slate coaster with photo's at 35% power and speed of 1200mm. Try black cardstock under the acrylic , really helps with engraving. Also if cutting you need air assist to cut down on charring. 20w diodes are getting good at cutting 19mm of plywood. I agrre with you about the z-height issue. Anyway just my 2 cents worth. BIG ISSUE Get some better eye protection. The orannge glasses will do the job. Cheers and sorry for my long rant lol
I could see it useful for cutting thin plywood in the case of making wooden lettering or thin wooden intricate parts or even for layered cutting (such as a wooden version of vin diesel instead of one made out of ham)
I love my laser cutter, and yours is *way* better. After I bought mine, I did better research and found that's what I should have bought instead. But I'm still quite happy with mine.
Thanks for the run-down on the problems with it. That Ortur still has advantages over mine, but I've found that mine has some unexpected advantages, too... Like I've never had it just stop and burn a spot. I think that's a printer problem, and not Lightburn.
I would definitely try one of those lazer engravers. I could make custom signs to hang on my shop wall. Incidentally, I just picked up a school bus stop sign similar to yours. I plan to use it with an alarm system, although I don't currently have one. Maybe it will be used as an indicator for someone approaching with a motion sensor. I have a number of signs that I've gotten over the years, including some from a bank that closed and was demolished. They are warnings for skateboarders.
Awesome Video! BTW You probably already know this, but in case you don't try to not run the laser at 100% ever, and just do more passes/cut slower and/or get a cheap aquarium pump(for air assist) to remove the soot to cut deeper without wearing out the diode. The degradation curve is very similar to Lithium Ion batteries when charged/discharged from 0-100%-0. The laser will last exponentially longer if you keep it under 70%.
I am jealous. I have been looking at one of these for awhile to cut thin ply wood and hardwood. I think I would rather deal with the smoke than the saw dust at this point.
I can only hope you engrave that ending frame of you holding an image of yourself on your next engraver.

I actually shone my laser in a sacrificial pair of those glasses.
The glasses melted and the paper behind was fine.
It's still glaringly bright and looking at the focal point will still feel uncomfortable.
But I don't think they will fail at protecting you from a frontal hit
Interestingly, 405 nm is the curing wavelength for printing resin....

The fact that the weird shield and glasses are different colors is very concerning
Forgive me for being a dummy, but why do you need them when the laser is facing down a few inches from the target? Does the light that reflects out damage your eyes?
@@tarstarkusz Yes just looking at it could blind you for life depending on the strength of the laser
If he's building a fume hood around it, he could just either make the hood opaque or get a tint in the appropriate spectrum and make the entire fume hood also a safety shield for the laser light
@@Yugophoto Personally, I would just use it on my stove top. The exhaust filter fan could probably get the fumes out.
