I heard much about these mysterious cheap Chinese "K40" Lasers. I decided to take the leap, and this is what I found out.

Hi there. Im pretty new to this but im wanting to purchase a machine like this one in the near future. I just want to know if this machine is able to cut through certain materials. Would it be able to cut shapes out of wood and perhaps even sheet metal. If not, could you please direct me to a reliable but relatively in expensive laser cutter that could perform this tasks. Many thanks geoffrey

Hello! This machine can absolutely cut wood up to 1/4" thick. It sadly cannot cut any metals, and to get a laser cutter that can cut metal is on the order of many thousands, or just getting a CNC plasma cutter, which again is many thousands of $$$.

Hi, Is the machine able to engrave on long items such as Greek/Fratenity/Sorority paddles? There looks like there is a slot on the back that will allow you to insert longer items.
Geeksmithing
Geeksmithing Hace un día
The slot in the back is an air exhaust vent. As they come, you can only fit an object 14" long in to engrave. You would need to do major modifications to get longer pieces in.

Hi first of all thanks for sharing your experiences regarding this machine. Im the owner of a small business making custom made raised garden beds in Denmark My question is can i use it for making little oval signs 3"x 2" in stainless steel for branding my products, im currently bying signs for about 9$ a piece and it totals about 500-800$ per year and furthemore im restoring vintage watches and likes to make custom dials for the ones that are beyond the patina look, and last does it lasercut too. Thanks in advance Yours sincerely Allan Lauritsen From Denmark Scandinavia

Sadly this machine cannot engrave metals. It can however affect surface coatings on the metals such as powdercoating or Anodization. Another option is to use a marking spray such as Enduramark or Ceramark before lasering. This leaves behind a nice dark marking where the laser hit. This could be used for small signage applications, and is also weather resistant.

Hi, Great Video! Would this setup be useful for little more usage than a hobby (For personalising hundreds of products a month)? Also the how does it to a decent engraving job on bamboo and anodised aluminium? P.S i saw the engraving on the mugs, they seemed to be anodised aluminium...

Hello! I cannot speak to whether or not this machine is capable of operating at production level quantities like that. Just be aware the laser tube generally lasts between 1000-1500 hours before being replaced. It does a great job at engraving bamboo (I have done bamboo cutting boards instagram.com/p/BnL2OobAe5L/?igshid=1cykcpe7dqt47 ) I have not tested the machine on anodized aluminum yet. The bottles you saw were powdercoated steel.

Do you think the exhaust would work any better with original fan as well as in line fan? I purchased the mods you recommended and thought maybe it would work well with both?
Geeksmithing
Geeksmithing Hace 3 días
But seriously, I would think the entire system would only pull as hard as the lowest common denominator fan device, as it would basically restrict the airflow as it wouldn't pass the air thru as fast.

I'm in the VERY beginning stages of researching laser engraving (this is the first video I've ever watched to even see how it is done!). I'm a knitter who sells products at markets and on Etsy, and currently purchase faux and real leather tags with my logo engraved on them through an Etsy shop, and I'm really considering trying to make my own, and possibly open it up to making tags for others. I'm a graphic designer that works with all Adobe software. Would a machine like this work for my needs? Is it over kill? Could it engrave, cut, and place the holes for sewing? A one stop shop? The tags are about an inch long by .5" wide. Sure appreciate any advice you can give! - Amanda

Geeksmithing Hace 5 días
Hi Amanda! Thanks for commenting! I think you being able to leverage Adobe product experience (i.e Illustrator) would set you to up to kick some serious ass with a laser! For less than $400 to get cutting/burning and engraving, it's definitely not Overkill! It's a perfect match for that skillset! I have yet to try it myself, but I have heard good things about working with leather and this machine. The specifics of veg tanned leather vs other kinds escapes me, as I just don't have much time invested in that area. I have heard it's important to have great ventilation as it smells really bad. (Also helps to have air assist installed on the laser as it helps prevent charring and makes cleaner cuts). I have leather and other fabric arts on the list for testing very soon. Please feel free to ask any other questions you come up with!

What color is the laser itself? Are safety glasses needed?
Geeksmithing
Geeksmithing Hace 9 días
This differs wildly from the blue/violet lasers. Those are super dangerous to the eye, even the ambient laser light visible on adjacent walls/surfaces can be damaging.
Geeksmithing
Geeksmithing Hace 9 días
It's infrared and invisible to the eye. With the lid down, there is very little risk, but I'm sure it is a nonzero chance nonetheless. I don't wear them, then again, I never open the lid when it's running.

K40 wouldn't be able to do anything with it even if it could, as the stock controller board cannot dynamically adjust the power thru software, so you wouldn't get any variance in the Z direction, to do a 3d engraving

It’s if they were both in front of you and free to take but only could have one ... side note could you do a vid on in your opinion what would be an awesome top 5 or 10 lasers to get cause this engraving is so kool to do id like to know what’s out there with someone’s knowledge about it
Geeksmithing
Geeksmithing Hace 10 días
Well, I would choose the K40 as I would be less willing to modify and remove the bottom out of a multi thousand dollar machine. Also, the fact that the software can be used without an internet connection is nice. But ultimately, I hate how they refer to the Glowforge as a 3D laser printer which in my opinion is very sleazy marketing.
Casey Pettus
Casey Pettus Hace 10 días
so you're asking if I would choose the 400 or the 4000 dollar machine, with roughly the same laser system? The Glowforge's power comes in the form of it's camera system and easy UI. The rest of the unit and engraving capabilities are a standard 40 watt laser system. Also the lighting system is pretty cool too.

That’s good to know! That makes me curious about more powerful Chinese lasers. i.e. rather than paying $4K for a 40W Glowforge, could a 200W no-name laser be had that actually could cut through metal or much thicker wood, or does that get into safety equipment one wouldn’t want in their garage?

I am about to buy one of this machines for cutting my balsa sheets from 1.5mm to 6mm thick. I build balsa model airplanes and I'm sure this machine will help me cutting formers, wing ribs etc. What would be the best base to locate the sheets to be cut by the machine?.

@Eduardo Barriga Caro I just use a small metal ruler and measure from the surface to the side of lens housing where it is on the inside. My K40 ideal focus distance is 60mm from lens, plus or minus 5mm, so there is basically a 10mm range where it it is pretty much in focus.

This machine would be awesome for that use! And those honeycomb tables/surfaces are great for lasering. The fewer contact points under your piece the better when cutting as it reduces the scorch marks on the underside.

@Jim Jones Thanks Jim! Happy to help! There are posts of differing opinions online about whether to use that grounding point or not even at all. From my research, I believe it is unnecessary in the US and many other countries where there is a standard ground pin in the home outlet itself. In many parts of the world, having a reliable ground as a standard part of the electrical grid is not always available (such as in China where this is produced). There a metal rod in the ground is your only solution. I believe that attaching the ground via the three prong outlet and using the metal rod driven in the ground simultaneously will cause a ground loop and its own host of problems with electronics. If you go the route of just using the ground in the power cord, unplug the machine and verify with a multimeter that there is continuity from the metal chassis and the grounding pin on the end of your power cord (to ensure that is wired correctly) :). Sorry for the long winded answer, but I agree that it is very important to get right. Let me know your thoughts, and keep a lookout for more K40 content this week!
Jim Jones
Jim Jones Hace 20 días
Thanks, I am learning and you seem to be the best source of info that I have found. I have another question, according to the book that came with the K40 unit, it says to drive a ground rod to connect to the unit achieving 5 ohms or less. I use to install CNC machine tool for 26 years and to achieve 5 ohms or less to ground is almost impossible. I question even driving a separate ground rod at all.

Thanks for this video. I ordered one of the DIY CNC engravers for $200. Sending it back. NO support anywhere, at all. I've only been using it for 2 days, and already having problems, but no one to tell me if it's something that may be wrong in the settings so it's going back. Plus, for $200 more dollars, the K40 does so much more AND comes mostly assembled. Two questions, please....I'm not very techie, is it fairly easy to understand and use right out of the box? Also, unfortunately, I don't have a shop or basement, and so have to use it in the house. (not ideal, I know). Anyway safety suggestions for using indoors? I'll be using it only on wood for the near future, at least, so I know there will be wood fumes. I may have to just vent it out the window.

@Laurie Schaerer the ones on Amazon have some benefits that some people tend to prefer. The sellers are certainly more communicative, have more consistent reviews on a particular manufacturer and you have some more avenues thru Amazon to utilize if something doesn't work or get shipped right. Some people, would rather just save the cash. :) 🤷‍♂️

@Geeksmithing Thanks so much for your replies. A Christmas ornament video would be wonderful!! I think I can make most anything given proper instructions. I'll be checking out the K40 Whisperer videos in the meantime.. I see that there are similar engravers on ebay for about $60 less, with free shipping, but they don't list the manufacturer for some reason. Do you recommend sticking with Amazon?
Geeksmithing
Geeksmithing Hace 20 días
@Laurie Schaerer in terms of wooden ornaments, this machine is awesome! I pumped out dozens of wooden ornaments last year of various sizes, styles and themes and it worked great cutting thru hardwood cherry that I used. I plan on making a tutorial video about the process, which includes all steps in inkscape to get design to the laser and engraved/cut out. I would recommend checking out the K40 Whisperer videos by ScorchWorks (the author of the software). It shows the simple/straightforward options and how to use it. Check it out while you are waiting on Amazon to do its thing. :)

@Geeksmithing Amazon has been great about my returning the CNC engraver. I'm sending it back tomorrow for a refund. I'm planning on ordering the one above once my refund is processed. Yes, putting that confounded thing together was a challenge. No real instructions, just pictures. 15 packages of screws, nuts, and washers, and not one of them labelled. My marriage survived that ordeal. :) However, the vector design software thing, that's a whole different story. The software that came with the engraver was LaserGRBL. They do have a website, but it's very vague, but still probably okay for someone with the right knowledge and experience. The extent of my editing software knowledge is Lightroom and Photoshop, and I only use them for photo editing, not any kind of graphics design. Am I getting in over my head? I'm really most interested in making ornaments with my photos, either engraved on wood disks or cut out, like your tiger (He looks like the Auburn University mascot, Aubie. If so, then War Eagle to you). Maybe I can progress on to making other items as I become more familiar with the machine.

Geeksmithing Hace 21 un día
Hey Laurie! Sorry you didn't watch this video sooner! If you were able to put together a DIY CNC kit, this this should be a piece of cake for you! The good thing about the K40, is that there is a pretty large community of people both on ESvid and even some great K40 Facebook groups that are great resources if you get stuck. I would say that the software is the trickiest part, but if you have used any vector design software, such as Inkscape or Illustrator, then you are already ahead of the game. While I do have my laser living in my workshop, it is in the basement of my house. Venting as an absolute necessity, but can be easily accomplished using a board with a hole cut in it shoved in the window, or even just draping the vent hose out of said window. Please hit me up if you have any more questions, and good luck! (this machine works great cutting and engraving wood pieces up to 1/4' in thickness! :) )

hi do u need to change the lazer every month or every sometimes of using it ??

I have heard the life of the laser tube is 1000-1500 hours, but that also depends on how high current you run jobs at. The harder you run it, the shorter lifespan will be. Best to not ever go over 12mA as a general rule.

One final question: I will primarily be engraving basswood rounds around 12"x15". Do you think I can get by with this unit or should I go with the larger eleksmaker mega diode laser?

@Dan McKenzie pretty much both.

How large, area-wise, of a piece can this handle? Saw a DIY mini air hockey table on Instructables that I wanted to try making, but then saw that several pieces requires laser cutting (including the playing surface of the table itself).

Hi! I'm considering purchasing a k40. I followed the Amazon link and noticed the description says "Cylindrical rotary device is NOT included, and cannot be added to this engraver. This engraver can only work on even surfaces." But you had no issue dropping in a rotary device after removing the clamp?

@Leon Kongsted Hey! Thanks for the comment!! I am happy to tell you that I'm literally working on the video right now and it should be out this week. It covers the entire process from how it works, building your own DIY rotary, how to hook it up, an how to engrave a project with it. :) Stay tuned!

@Geeksmithing I too have bought a 40w engraver, still in the package, and I will also be engraving bottles, glasses and beer mugs. Maybe it's "lost in translation" but I don't really understand the rotary and y-axis parts. So for me the phrase "don't tell it - show it" rings true. So i join the crowd in urging you to make that video - like - yesterday!!! ;-) Great video btw. this one is.

@Geeksmithing makes sense. Thanks a lot for the tips... I'm still trying to make my mind up about this or a 4060 50w laser.... Tough choice :)

There are posts that hold up the clamping bed as seen in video. You could attach a piece of metal here to use as a bed. Or corrugated metal mesh. You could also use a wooden panel as a bed, but beware that over extended time, the wood can accumulate charred areas that can smolder and cause a fire, so metal is best.
Mangy_Dog
Mangy_Dog Hace 27 días
@Geeksmithing But you need to design and fit your own bed?
Geeksmithing
Geeksmithing Hace 27 días
The work area estimates they give are often wrong or deceiving. You are right, if you leave the clamp thing in, it is far less than that. If you remove it, your cutting area is like 35cm * 22cm.

They are pretty darn similar...Orion Tech is probably more popular from what I hear. And inkscape is pretty easy. Tons of tutorials put there, and the workflow is very straightforward.

Found this video from you talking about it on the podcast. I'm thinking of selling my glowforge and gettingone of these k40s what are your thoughts on making that move? I really want to be able to do cups and I also taller items. What's the max Z height on a k40? Thanks and keep up the great work!

Hey! Thanks for listening!🎙️ Honestly, the huge difference in price just doesn't justify the small difference in features between them. Glowforge has a larger cutting area (which could make a difference for many people) and it has the camera system but powerwise they are comparable. Though with some simple modifications, the K40 can get an unlimited Z cutting height, and a similar camera system. The stock Z cutting height is only 3.5", which can be ok for even rotary engraving items up to 2.75" in diameter with the rotary setup I made. If you cut the bottom out, this limitation is obviously no longer a factor. There are also some safety features that the Glowforge has, such as not allowing you to put your hands in the laser while it's firing, but that is also a simple and cheap mod. Hope that helps!

Absolutely. Up to 6mm wood, acrylic, cardboard, plastics (as long as they don't have vinyl in them as that is dangerous to laser)
