Never have I needed that stupid fire suppression system with ANY of my lasers in the years I have been running them. I have cut cardboards on all of them and many, many other materials. I run a business with C02 and Diode lasers, the only small fire I had was when I was testing a specific kind of door mat that used Coconut hairs and I was right there because I knew the risk as I DID MY RESEARCH. Also, having to run the file from the machine button, that is on LTT for buying without doing their research. Speak with your wallet and don't give vendors who do this kind of thing or online only software (like Glowforge and Cricut) your money. They preach that we speak with our wallet and they do not follow their own advice.

Others have been lack of items such as upgraded exhaust and/or air assist. Not one that I have seen was because of the dangerous machine and a flammable material meeting for a late night tussle.

[@LPcrazy_88]

@@shawnhartmann1750 You seem to have missed quite a lot of what they tried to drive home in this video. This product is geared towards hobbyists and the default package is not safe period. Scoff all you want at a cheap safety system, but when you're spending thousands of dollars on a product, 200 for slight bit more peace of mind makes perfect sense to me. Accidents happen, failures happen, new people happen. I repair and maintain medical equipment, I work with just about about every laser that exists in my diagnostic equipment and in the medical equipment themselves from Dermatology lasers to CT machines. I really appreciate how they made an emphasis on the eye protection specifically because when I train new people that's one of the biggest things I harp on. Never trust the manufacturer, and check the wavelength rated on the glasses and the output of the device. They clearly didn't do their research but they also admitted as much and it's not exactly unsurprising. Lasers are cool and most people think "oh hey if it wasn't safe why would the manufacturer sell it". I can't speak to your software point, I have no idea what you're talking about because I have no experience using any of that. I will say xTool has a 30 day return window, and I highly doubt they were within that window for the first video they mentioned this thing.

He let the laser tickle the edge of a single board and then whinged about safety the other 17 minutes. They need to do better than that. Other KZbinrs that review these machines on weekly to daily basis do far more. Grid power tests, cut tests of various thicknesses, engraving on metal, plastic, paper, felt, cardboard, they test the rotary unit, the efficiency of the extraction from the manufacturers enclosure and so on.

[@OddlyIncredible]

The scariest thing about laser cutter/engravers systems generally and open-frame setups like this in particular is the fact that human vision has a lot of failsafes and compensation mechanisms built into it, and you have to do a _LOT_ of damage to your eyes before you actually begin to notice. It's not uncommon for people that work with lasers to have retinas the look like Swiss cheese but are still able to "see" more-or-less because their brains are editing out the blind spots. To give an idea how dangerous a setup this really is: _The light from a 40W blue laser will almost instantly burn a hole in your retina just from the dot of laser light reflecting off a white wall._ One of these days I might build myself a laser cutter/engraver, but if I do it'll be a fully enclosed box with an optically shielded camera inside to use to see what it's doing, and safety interlocks galore so it won't kill my peepers.

[@OddlyIncredible]

I have a green laser pointer. Only 5mW. I still treat it like an eye hazard even though it's not powerful enough to be one because holy _crap_ it's bright to the eye.

[@NG-VQ37VHR]

Personally, I think the hysteria over laser cutters/engravers is over blown. I regularly work with a 2500 watt CO2 laser built by Cincinnati that has no issue cutting through 3/8" stainless. We've ran it for 15 years without an enclosure. Just don't be dumb and you'll be fine. It's the same with any tool you purchase. These small lasers aren't any more dangerous than an angle grinder. That's not to say an angle grinder isn't dangerous. I've personally seen an inch long metal wire sticking out of someone's eye, which had to be surgically removed, just because they forgot to put their glasses back on. But go watch any review video of an angle grinder. You won't find the same hysteria. People tend to handle self-preservation just fine on their own. Those that don't, will end up hurting themselves even with you telling them they need an enclosure.

[@OddlyIncredible]

@@NG-VQ37VHR _" Just don't be dumb and you'll be fine."_ Have you _talked_ to people lately? _"Dumb" is the norm._ These are being sold to Joe & Jane Sixpack, who more than likely don't have any actual experience working with eye-hazardous lasers. The threat profile here is that you can get eye damage and not even know it, and in a home or home-workshop environment you have secondary victims (e.g., family/pets) that can also get hurt without realizing it. A hopefully-trained professional working with a commercial system that will almost certainly have integrated safeties (for example, I'd wager your CO2 system has interlocks to keep things like fingers out of the beam path) is a whole different animal than an amateur with a basic consumer system that has no real safeties to speak of aside from a little plastic shield around the diode's output end.

[@Black3ternity]

​@@NG-VQ37VHR IMHO the main issue is that a laser seems fun and tinkery for everyone. Oh you can make nice wedding cards and wood puzzles. Theehee. An Angle grinder is loud, noisy and scary because it is a rotating machine. Laser? Probably fine because it has a tinted glass and I have fancy googles. Yes, both are dangerous. So is a kitchen knife. But you know a kitchen knife can be sharp as heck or stab your leg if it falls. Because you were taught properly. Laser? Oh it's just a 3D Printer or a cutting plotter with a laser instead of a knife. What could probably happen, right?

[@TheBackyardChemist]

@@NG-VQ37VHR The hazard of cheap laser cutters like this is party psychological. An angle grinder is loud and scary, and spins really fast. It commands a certain level of respect even in many people who know nothing about it, and mechanical hazards are in general more relatable for most people. But high-powered lasers are something that most people have no concept about, and something that fits on your desk, relatively quiet, etc. does not put the fear into people nearly as much, and hazards like reflected light are not as obvious.

Also the Enclosure shoud have a Detection if the Panel is open. and if it is, it should cut power to the LaserHead And requiring to press a button INSIDE of the Enclosure, so you have to start the Laser without the Enclosure closed is Highly Dangerous and Dumb...

I am not faulting Linus, Yvonne, or those who helped put together the video, cheap laser marketing preys on people who want the tech without knowing the important safety considerations; I hope they built an enclosure or replaced that machine. The conclusions here are solid: these types of unenclosed, high powered lasers are simply not safe, and really should not be used by people who don't know what they are doing. I like that this xTool system is trying to bring a safer laser system to a lower price point, which is definitely better than the super cheap extruded aluminum AliExpress kits, but it should all be sold as one kit. I still fear someone who doesn't know better thinking they dont need the extra safety equipment and hurting themselves. And the people who do know better are probably looking for a more professional laser system as you alluded to in your video..

Not sure about their fire suppression system though. I don't know if this video has been in the works for a while, but I'm glad it's out now after the controversy.

[@gmillerjr]

I’d have to disagree. I felt like he just opened the box one day and decided to do the video. It looks almost like no research was done and he did not have a good grasp of understanding the basics of the machine. For instance positioning is 101 and spelled out in the software when you go to process it. There was nothing in depth to this. Safety is important and I’d never fault anyone to go above and beyond what they need, but the shields and glasses are rated for safe use with these. They’re made for reflective or stray beams. If you have someone pointing the laser directly at your eyes then there’s something else wrong.

[@Yosuru]

17:35, He really looked like Linus in this frame holy #?!@.

Additionally regarding the leather, be aware of the tannage and treatments of the leather. Oil tanned hides will often just burn

[@Chefbigpp]

Linus bigger brother Linos

[@Gertol31]

Great video and Solidworks appears to me to be almost the perfect sponsor for this kind of video.

[@RedCoyote]

One note with leather: you also want to look into if the leather is veg tanned or chrome tanned. While this is from second hand, I've heard that you can also get bad fumes from chrome tanned leathers, since they're usually tanned with chromium.

Me for years: i need a laser tool for my shop me after watching this video: oh its actually dangerous, maybe i dont need one

[@tynanstack7924]

There are some that can be safer when used properly just make sure you do your homework and are aware of what risks exist!

[@tristanxxxx]

Great video that taught me a lot. I was hanging on every word. I'm not into every single video Short Circuit puts out, but this one was worth my time.

[@robkaminsky9736]

Most informative vid I’ve seen for a while. Really feel safety was important AND he was being honest and sincere. 10/10

[@collinclark6086]

This was very cool to watch. I have operated some large co2 lasers (4kw) as well as a fibre laser (2kw) and this is definitely the easies to use for the hobbyist. I agree with the enclosure argument, since more than a few watts makes for a very dangerous laser.

[@BlitzRazor]

Not so sure if this is considered a short circuit due to the amount of kinda review stuff in it, but I do love the fact that there is so much information packed into the video

[@DizzyBusy]

This video is more about the safety and add-ons you can get for the product. A full LTT video would be about trying the laser out for different scenarios, I guess?

[@justbasil7308]

Never thought I'd have minecraft Steve reviewing a laser cutter. I'm surprised how much I like it though

[@loopymind]

love the honesty and the repeated safety warnings

[@dreadafk]

This was a very informative and chill vid. Loved it.

[@evilleader1991]

No screaming Linus is always welcome

[@MrHellmeowmix]

absolutely love the emphasis put on safety with a machine like this. has a way smaller laser cutter that nearly destroyed my home. luckily a smoke detector in my 'office' room alerted me to the fire and i only lost a desk

[@ThrowingItAway]

Tynan is chill and some how not boring like Steve from GN

[@maulerrw]

I have a 3w blue laser, it will burn through a leaf in about 4 seconds and looks like an infinite lightsaber shooting into the air. 40w is over 13 times as strong. It is so powerful that even a mildly shiny object would reflect enough that it could cause permanent and instant loss of sight. a full reflection of a metal surface or a direct hit would instantly blind you and boil a pocket inside your eyeball. it only takes less than 0.1w of laser power to cause potentially permanent eye damage, they absolutely deserve serious respect and maximum safety

[@Schatten.mensch]

The fact that something like this is freely available to purchase for anyone who might not know what they are doing is somewhat terrifying - I know, I know, the usual american perspective to something like this is that it's peoples own fault if they fuck around with something hazardous but in general the amount of class 4 lasers freely available for purchase is insane. No disrespect to her, but if Yvonne had tried to use this thing on her own she'd likely be blind by now or would be suffering from other severe health issues. On that note, I do hope we get more content with Tynan in this style if he has the time to do it, this was one of the best short circuits you have ever made. Oh, and do be careful with the camera as well - you do use some rather expensive cameras after all and a laser like this can easily punch holes into the sensor as well. I have seen youtubes favorite laser and chemistry nutter styropyro kill one of his cameras with stray reflections from a high powered laser. (although admittedly that was a million watt pulse laser from china, not a cutter ^^)

[@dotcomdudee]

Really like Tynan. He's so easy to watch!

[@Velkanis]

short circuit video that aint so short? aight thats cool also heyo tynan! glad to have you on camera again

[@abudhabikid]

hell yes, give me more Tynan videos

[@carlospcpro]

I like this Linus version. Careful and without dropping stuff

[@stevengunter3457]

i like tynan as a host on of tech type tools. he is a great fit for this. also funny guy. an he not missing anything important about the device which is great for someone like me that looking at one of these.

[@Rudy2k5]

Usually, when Tynan is in front of the camera, shit can get serious very quickly haha He has some of the craziest ideas, but at the same time he knows his stuff like no one else. So if he's concerned about safety issue, you must listen to him.

[@galgrunfeld9954]

LMG? Amazing. Seriously Entertaining - Really!

[@LelouchLamperouge235]

You pronounced "Průša" much closer to the original Czech way here than in the actual Mark 4 unboxing.
