Im upgrading my K40 clone to a 60 watt tube and power supply. I also have a Meanwell supply from an old Ender 3 pro I want to use , keeping the main PSU strictly for the tube driver. However, the wiring is proving to br problematic for me. I wish we could post photos here, too for a better example of what Im about. The stock 40 watt supply is radically different from the Cloudray M60 as far as connections go. I searched the internet for wiring diagrams but no luck for my specific power supplys. your video is excellent in as much as it addresses other issues I will face in modding. Thank you!

Light right in your eyes - that sucks

For the front vents, you can increase the air flow through them simply by twisting all of the metal strips running up and down. About 15-20 degrees each should do it

great video. my question is what is the switch for next to the E stop? thanks

I was amuzed, guy says about the air duct that it is simple physics and misses totally the point that having the opening smaller creates faster airflow...

You could add a piece of spark arrestor screen over the hole in the back

how did you set up the focal length?

you probably shouldn't move your servos around while they are powered that's a good way to fry your control board

Can it run lightburn? If so I'm in!

can you maybe some time do a video where you test the cutting method on the machine with acrylics? great video btw :D

Decreasing diameter increases velocity!

Can you tell me the name of the pc software that you use please ?

Loads of interesting content fella, you missed one crucial thing though. When you took the bed out and messed up the laser mirrors. How did you realign the laser once you put the bed back in?? That was a very important step to miss out. I'd love to extend my printing footprint but I'm not confident in the realignment of the laser. Please help Many thanks in advance sir. Keep up the cool content 👊

Vevor 40W is the same as K40?

I know this an after-the-fact statement, but you could have placed a metallic screen over the rear air-vent if you were concerned with embers. Just a thought.

Great video Eric! Just wondering how after a year how it's all working for you with the K40? Any other modifications or changes? Did you figure out that taped thing on the waterline by the laser?? 🤣😂😅 I bought the exact same one and have done quite a few mods to mine as well 😊. I think I seen somewhere on one of your other videos that you're from Goderich ON, I'm not too far from you, Windsor ON lol. Good to see a fellow Ontarian on KZfaq!

where can I find the code for the air assist nozzle mate?

raw footage version is great! Are you selling the 3D printed parts needed for these mods? Thanks for sharing!

k40 whisperer was a game changer for the k40...i now have built my own 600x400 co2 laser using the k40 control board, 45w spt laser.....have had for 3+ years.....spt makes great tubes.....they are actually tested with info like peak power......made motorized bed out of 1x1 steel tube and 3d printed parts....total cost was $900....well worth it as its paid for itself many times over

this is the first time I've seen so many colors on a blinds. haha

HMKme Media, I'm planning to purchase this machine, but I think assembling it myself just puts me off. Doe's the machine come fully assembled, connected to your PC switch it on ready to go.

Why invest money into this piece of equipment if you have to rehaul it after you get it. Everybody, like myself, is not laser smart, not even to understand what you are sharing.

Great vid and a lot of good ideas! Just one thing, watch how fast you slide the gantry! - The steppers motors become generators when spun quickly; this can back-feed voltage to the board and smoke it!

This is a GREAT resource THANK YOU! do you have a list of all the accessories you added?

hey Eric, i wonder if i could buy a air assist nozzle that you made on your 3D printer. I have been looking for one that is gonna fit on my K40 but I have not been able to get a better one like yours. please. I'll pay for the shipping cost and for the cost of the 3D printed. Please. I would appreciate if you could. Thank you.

Great video!! I am in Korea. Is the antifreeze used for laser tube cooling mixed with water? What percentage, then, each?

Got a K40 about a week ago, really happy with it. The optics seem to be in good alignment out of the box, the bed has a removable flush plate covering the clamp in those things, and the top of the bed seems to be about 1.5-2mm below the focal point of the lens. The extractor fan seems to be a decent equipment fan with a good flow, not one of those junky plastic boxes most of them apparently come with, and the extraction nozzle inside is the full width of the working area and seems quite effective, and it came with one of those spiral foil type hoses, which seems a bit more substantial than the blue plastic ones I've seen with other people's. All in all, I'm very happy with it, as most of the things which everyone says you absolutely must modify seem to have been done for me. All I've had to do myself is properly to earth the case, and to install an ammeter in series with the tube, since I got one of the ones with a digital display. All in all, having looked into these machines a couple of times over the years, I'm only sorry I didn't take the plunge much sooner.

Next video we will set up basic Wordpress and automatic content posting to make the site fully automated to make some $$$

Now that you remove the protruding vent, what maximun size workpiece you can put inside.. thanks

Hi What is your 3D Printer, looks nice

Thanks for the heads up

Come on over to the new MKME Outdoors channel! kzfaq.info/love/TUoaahtQ3eIBtUvwaE2ixw Lots of repairs and outdoors fun coming. Oh and garage mail of course...

I have an issue I just bought it. Everything look okay accept there’s no laser when trying the laser ? Do you have any experience with this issue?

thank you very much for the video. excellent info! just a question, if I may: what’s the total printable area now? thanks again!

Hello, great video. I´m building CNC laser CO2 of 40W. I´m using the M2 nano controller, same your machine, but I dont know Which motor use. I know are Nema 17, but I´d like to know the model. SO, Can you view the model motor in your machine . the motor has a label o sticker where indicate the model, please. Regard

Thank you for taking the time to make and share this video, This is one of the better ones. I ordered my first K40 a few days ago and the tracking says I should get it in 3 days. I looked down in the comments section of this video and on your linked pages and cant find the files to print the air assist. Would you be willing to share or sell them? Again Thank you.

All the videos I watched used distilled water for coolant you are the first who has used anti freeze. I have now had 2 tubes crack due to freezing! Have you had any problems using anti freeze or is that the way I should go too?

Would you be able to laser staple a polymer 80 frame

Hi there, i just bought my k40 laser. First time i turn it on, the laser home point was at the top right corner. How to make ot to top left corner.?

I made a point of running the stock hardware and software for a couple of engraves to find any defective parts before gutting the machine for upgrades like you did.

pew pew... pew pew pew..... thank you for the laugh sir

I recently purchased a preenex 4w0 laser and was told it could NOT be modified to use a rotary tool. Are there models that cannot be hacked to use one?

TURN DOWN THE BLASTING SOUNDS

Does anyone sell these pre modded, ready to go, Im a buyer .

Eric, thank you for sharing, I do have a question. Can a K40 laser engrave on glass and natural stone?

Got my hands on a K40 a few days ago. I didn't have to set up the mirrors, they were all set up already.... great video... Now I must mod the exhaust too...
