I never thought about grounding in the garage where they go to used, thank you very much you may just have saved me!!
Thank you! I will get a K40 now as well, knowing that there are great guys like you out there with the knowledge to get these things working...thanks again.
This kind of comments keeps me motivated. Thank you for your feedback!
Really great video. I bought this laser and it has been sitting around for a while now because I was lost on the software. Many thanks!
Great video mate, As a newbie expecting this machine shortly I'm very happy with the information covered in your video. I know limited about cutting so thank you.
Hi! I'm also very new to this and am wondering how you found your way with it? I'd appreciate any advice 😊
Hello! Thanks for this. I'm still a little nervous about my first cut so I really appreciated this video.
(4 months later) How it went? Any success?
It's about 3 years since I have it, even the video it's posted later. The laser tube that i changed in this video is still working, everything is perfect. Not suggesting that will be the case for every k40, but I still use it. I was cutting some christmas ornaments when you posted this message :D
Brilliant starting point. Thanks!
Straight and simple to the point. Thank you. Greetings from Sicily buddy
Great video thank you for your time
Thank you, I appreciate your kind words!
This was a really great video. I really struggled with the software that came with the laser. This K40 Whisperer software is WAY better. I just did a project with the new software and it worked excellent. Thanks for this video. I had not used my laser for a few years. Mostly because of the software struggle. Oh and the direction that came with mine, TERRIBLE. Thanks again!
I am very glad it helped, thanks for appreciation ❤️
Great video
Thank you my friend, I have just placed and order for a k40 today after watching your video, and if all goes wrong I am blaming you LOL only kidding.
Haha, fingers crossed! Hope it will work on the first try. Keep me updated with the status :D
Thanks bro..just got me this machine n dont know how to setup..ur explaination very clear..good job and thank you
Glad I could help you. Thanks for appreciation!
Where did you purchase yours if you don't mind me asking
@@boknows3915 Aliexpress, but I have purchased 2 k40 with tube broken, so finally I bought the tube separately and replaced. Exactly what you see on video.
@@IndoorTechnology thank you for your response! I was iffy about aliexpress but I keep hearing more people ordering from them.
good idea for my laser
Thanks for this video! Nervous about ordering it on aliexpress so fingers crossed lmao
Did you pull the trigger and order through aliexpress? How'd it go?
awesome thanks
Thank you for this video I was struggling for weeks with the software I received with the machine. Now my struggle is my machine is not cutting through the 3mm acrylic. I have to run it at least three times before it goes through
Very helpfull
Nice video 💞
Nice
Omg, this video was fantastic! So next i m guessing that you ll post the video on how to manually calibrate the k40 laser beam?
In the near future, yes, but it's not the next video, as I'm preparing some extraordinary DIY projects for next week.
i try with my "new" qualitech 203mini because i forget my keys of the soft/ thank you to author of this video
Great upload thanks👍 what sort of results do you get engraving slate ? Thanks
I like this video first because you talked about something nobody really talk about with these machines is the WATER PUMP no other videos talk about it never even knew it had a water pump you have to keep up with cus other people videos be skipping this part so thanks
Thank you for your feedback! I am very glad I could give you useful info!
While the K40 is a popular entry-level option, if you’re looking for a laser cutter that offers superior performance and reliability, I highly recommend the Monport Laser. The Monport Laser provides advanced features, greater precision, and more robust construction, making it an excellent choice for both beginners and experienced users. It ensures consistent and high-quality results across various materials, from wood and acrylic to metal and glass. Investing in a Monport Laser means investing in a tool that will elevate your projects with professional-grade quality and ease of use.
Mind sharing where you got that plane file from? Id love to cut one for my boy. My K40 shows up Monday.
What goggles did you buy? I've tried searching but there's so many different options and I don't know which ones I'm supposed to choose
Can do video on setting cutting Engraving
As got mine and lost do mdf 3/5 mm and Birch plywood sheet 3/4/5mm
I do tile and stale cant find no online
Great video. I just got my k40. How are you setting the focus for thicker material vs thinner material? Also, have you tried a rotary on the k40? Finally, have you added a knozzle for air assist? If so what pump and nozzle did you get? Thanks. After about 7 videos I finally found one to truly get me started.
Yes, the nozzle for air assist it's added separately.
My K40, same as yours, came with some silicon glue. Do you know what is it supposed to be for? Great vid. Subscribed.
What modification did you make to the smoke extractor fan to improve its performance? Thanks .
Do you have a video with recommended settings for cutting/engraving different materials?
I don't have that yet, pretty sure will have that in the future, but unfortunately I had a few good months totally distracted by other things, and haven't time to make more videos (which I love to do). But be sure you're subscribed, I will surely post interesting content soon with projects & tutorials on k40 lasers.
I have purchased one and I have two pendrives: One with the software and the another one is a USB KEY. What is it used for?
Hi does the cut 3MM acrylic. Would it be possible if you could do a video on engraving and cutting acrylic please that would be fantastic
Hi! Yes, it cuts & engrave 3mm acrylic perfectly. I will do a video in the future with that but I think you can already find on yt some examples.
U gained a subscriber how long did it take to cut that logo 😊
Where did you get this model with the built in ammeter? I’ve been searching all over for this exact k40 model but can’t find it.
I'll get home in a few hours and see from where i've ordered it.
Hello! Thanks for this video , I have a question: can this machine cut 0.5mm thick aluminum paper?
Hello! This laser in my video cannot cut any thickness of aluminum. You need minimum 100W co2 laser to cut and engrave that size of aluminum, but for working with metals, a better fit are FIBER LASERS. Those are used in industry to cut small thickness of aluminum and engrave them. All the best!
@@IndoorTechnology thanks a lot
I bought AK 40 engraver and the laser tube is wrapped in plastic. Should I remove the plastic from the laser tube I didn’t know if it was for packing
Inkscape settings click precise page or selection as well as content. This was said fast.
It’s in Document Properties.
hi, i dont have mA meter on my k40 machine, only adjustable power.
what power do you advice to engrave and cut for example a 3mm plywood.
I usually use 100mm/s with 10 power... i dont even know what that 10 means. I think i dont get good result as i saw other people do on youtube.
And, can you share how do you finish your engrave?
I could not know because that power you are using it's not calibrated on anything ... I really recommend putting an ampmeter of ~30 or 40 miliamps so you can see what that power you have means. Then we can talk about cutting speeds. I usually engrave with 6-8 miliamps and speed from 150 to 300mm/s and cut with 12ma and speed from 13 to 15 mm/s (on poplar plywood).
I have same issue with the machine I got as same model in the video so I got software as you saying but I can’t start the machine I don’t know what to do thanks for help
If you're opening K40 Whisperer and clicking on "Initialize Laser Cutter," but nothing happens, there are a few things you should check. First, make sure your cable connections are secure. You should also check if your computer recognizes the USB connection, as you may have an issue with your operating system.
If you're still having trouble, try installing K40 Whisperer on another computer to see if it works there. If you're still having issues, it's possible that the M2 Nano motherboard has a problem. In that case, you may need to consider replacing it. These are your options.
What thickness does this cut?
hi can this machine engrave on silver and gemstones exp ( jade, agate, hematite)??
please let me know asap.
thanks
Not really. Search for fiber lasers. Those are more suitable for that kind of engravings.
Does the water cooler items come with the K40, or need to buy separate! If so..where from?
The water pump usually comes with k40. That means you can recirculate water, but not cool it. If you have to do only short time engravings or cuttings and your room temperature is not high, you don't need any water chiller. You need to keep the water at ~20 degrees celsius. This is the temperature I find the best for the laser ... the very maximum being around 25. Now if you do hours of cutting and engravings, you can buy an industrial chiller to do the cooling for you OR, how I do it as I don't do hours of engravings very often, I have two recipients. A smaller one with distilled water, which I recirculate, and a larger one with tap water with ICE from freezer. So I put the recipient with distilled water in the one with tap water. When I need to lower the temperature, I just add some ice in the recipient with tap water (I usually store in freezer 4-5 small bottles with water, so they can freeze) - so this is the best workaround I could find so I don't need to invest in industrial chiller. All the best!
@@IndoorTechnology Sound advice, thanks for the information.
Great video but you don’t mention the USB key ? I cannot get my machine to connect to laser as the USB key doesn’t register. Any help appreciated.
8:32 - I did talk about the software a lot and gave step by step instructions. Maybe you haven't watched my video.
Please can I use the k40 laser cutter to cut an acrylic sheet
Yes
Hi, I'm just wondering if the only steps with grounding is to check the power plug, and sand the little grounding bracket. You don't need to earth the machine, do you?
The safety part of your video put the fear of God into me, that's all. I can't wait to check out your video on centering the beam. Great video, so thanks!!!
You sand there and put that bracket to make sure the grounding (earth) from your plug is connected to the case - so in case your power supply or the wire from laser, that have lots of voltage is failing and giving voltage to the case, you will be safe - but anyway, your plugs must have grounding, it is specified in the video.
I just got this machine but i feel like it has so many safety concerns. i live in an apartment i dont know if i should be using it
Any laser machine has safety concerns. It's true that with this specific one you have to be more careful, but if you follow the advices in this video, I assure you everything is 100% fine. If you're using it in an apartment, than most likely your grounding works. The big issue is with the smoke. In an apartment you will need to buy some special smoke filter, which is pretty expensive, and I'm pretty sure your neighbours won't like the smoke, if you plan to evacuate the smoke outside. I used it once in my apartment and my neighbours were not happy :)).
How is the k40 a year later?
Hey there !
I am having issues with the key "USB" , every time I plug it into my pc it states USB malfunctioned, therefore I haven't been able to use it. I have been looking around for information but honestly I can't find a resolution to this issue.
The USB is marked it says lihuiyu studio labs - 2019.08.15 .If you are familiar with this issue what would you recommend me to do?.
nice videos I have the exact same laser engraver but the brand is preenex.
I'll appreciate it if your can help me out with this one !,
Thank you!.
Just follow this video and the steps. You don't need that USB at all.
@@IndoorTechnology I followed the steps on your video, I installed whisperer but when I try to hit initialize or attempt to control the laser machine it doesn't work at all. I get this error message.
laser USB device not found (libusb driver may not be installed).
I will appreciate it if you know what would be the resolution to this issue, thank you!
I tried to delete the usb port from device manager, although it never showed up . I tried all... Only thing I notice is my windows version is W11, and apparently the program works up to windows 10.
@@MASKART-fi1xl then reinstall k40 whisperer and make sure you also select that driver, to be installed. You can see the exact instructions on this link: www.scorchworks.com/K40whisperer/k40w_setup.html
@@IndoorTechnology yes that's exactly what I did, The web site also asks me to do the same thing but the driver never gets installed. My computer seems to be unable to read the USB connector from the machine. I honestly don't know what else to do . I tried it all.
Could this machine cut 5mm carbon fiber?
Did you pay for all 3 lasers or did aliexpress send another one?
For the first one that came broken, I have requested a refund, after making a video confirming that the laser is broken, so I bought the second one. The laser was again broken, so I have decided to replace only the tube. So asked for a partially refund, put some extra pennies, and bought a higher quality tube and replaced it myself. The tube is still working this day.
So yes, you are safe on both aliexpress or ebay. If your item comes broken, you will be able to refund.
@@IndoorTechnology Thanks.
new subscriber here how do you like your machine?
Can i use illustrator instead of inkscape? Because it doesn t work and i don t know why?
Sure, Illustrator or any vector software will work fine. Watch my recent videos, where I also used Illustrator.
Can i use this to make rubber stamp?
Yes, you can make rubber stamp with it.
the red color(cutting) does not appear in my Whisperer !?
Make sure your SVG is in RGB format and the color is pure RED - look at minute 10:00 - there you can see the three color for RGB. Make sure R is all the way up (255) and G & B all the way down (0). So it needs to be full red, otherwise it won't work. Tell me if you sort it out.
can it cut thin metal ? like 1mm max ?
Hi! No, it cannot cut any metal this specific one. For thin metal you will need at least 120-150w co2 laser, or, search for fiber lasers, which are ment to cut/engrave metals - but those are not on a budget.
Please how can I contact you privately, they’re questions I would love to ask.
How does the engraving work on stone?
Hi! Engraving should work on stone fine, but it will depend on stone shape, density, color, etc. Of course, testing to see how you can get perfect results is the key.
@@IndoorTechnology just ordered it
@@ateliertwintes8061 Cool! Waiting for your reply when you have it, to see if everything went smooth.
@@IndoorTechnology its shipped!
its in. I have used k40 whisper. Works But when i use multyply vectorcut rounds it wil first go to the home. Wich make it move a little and not cut the same line
Limited technical documentation. Troubleshooting the k40 laser is a frustrating experience due to the lack of detailed technical information
The k40 whisper. Is telling me it could harm my computer & not working? Any other suggestions
What Operating System are u using? Just make sure you download it from here: www.scorchworks.com/K40whisperer/k40whisperer.html and if it's a message that says it can harm your computer, then it's just a false alert. Just ignore it and move forward. Nothing to worry about.
@@IndoorTechnology I'm on a laptop. I just followed the instructions. It's downloaded but when I go to open it ... It's says it can't do it cos it's harmful? . I'm not really sure 😬 . Just don't understand PCs lol .I get lost. Just want to get to the page with the . . Red -blue -black. ... So I can try cut one of them out. Been saying for years I'll get one . But this was the reason why I didn't 😅 I don't have a clue. But I'm trying
@@minimotomad2762 You should see also a "Proceed anyway" or something like that to bypass the restriction message. Or "continue at your own risk". If you could send a print or something with the exact mesaage you get, maybe I can help you forward.
@@IndoorTechnology hi buddy 👍 . So I managed to finally download it. But at the bottom of the screen. In red. It's saying. USB error. Laser USB device not found. . Lib USB driver may not be installed?
@@minimotomad2762 Is your cable connected and laser powered? Are u using windows?
Mine does nothing put key card in it blinks , THE END
WIll this engrave slate?
If you are talking about metal, than no. Fiber lasers are used to engrave metal. CO2 wavelength doesn't like metal. You could paint it and engrave the paint, but that will be all
@@IndoorTechnology Slate is not metal, it's slate.. a fine-grained grey, green, or bluish-purple metamorphic rock easily split into smooth, flat plates.
@@adrianworsdall3082 ah, ok, for rocks co2 works pretty good. Here also depends on the rock but usually this type of laser is doing pretty good engraving rocks.
why the loud music?
NOOO! I'll never know if the plane crashed or not!?
It didn't, the plane it's safe :))
Liar!
Why do we need Music in a teaching Video
Music can be used in a teaching video for a variety of reasons. Here are some potential benefits:
Enhance learning and memory retention: Music can help create a positive and engaging learning environment, which can help students retain information better.
Create an emotional connection: Music can help create an emotional connection with the content being taught, which can increase student engagement and motivation.
Increase focus: Music can help students to focus on the material being taught by masking distracting sounds in the environment.
Set the tone: Music can be used to set the tone of the video, which can help to create a specific mood or atmosphere that is appropriate for the content being taught.
Increase enjoyment: Adding music to a teaching video can make the experience more enjoyable for students, which can help to increase their overall interest in the material.
It's important to note that the use of music in teaching videos should be purposeful and appropriate for the content being taught. Additionally, it's important to ensure that the music doesn't overpower or distract from the main message of the video.
