K40/Chinese CO2 laser cutter/engraver buyer’s guide

Рет қаралды 361,288

Күн бұрын

I just got myself a CO2 laser cutter and it was daunting knowing which one to buy. After many hours of research, I present to you this buyer’s guide with a breakdown of what features and specifications to look for when shopping. In this video I am definitely standing on the shoulders of giants, so please check out the links to these wonderful sites below.
One thing I didn’t mention is it makes no difference what colour the outside of the laser is! This is completely arbitrary and tells you nothing about whether a particular machine is good or not.
These machines are definitely for tinkerers and the risks to safety are quite high, so please only consider one of these machines if you are suitably knowledgeable, confident and experienced.
Ray from Cohesion3D was another great resource in preparing this video. He was honest and patient in answering my beginner questions right at the beginning. The Cohesion3D laser board is already fitted and working very well with Lightburn. I look forward to showcasing it with a guide in a future video.

Michael - Pro tip on removing paper backing on just about anything. Use your heat gun or even a hair dryer. Just need to get that glue warmed up and it peels off easy. Once you get it started use the heat and slowly peel it off. I went decades without knowing this trick and now I can remove just about any sticker off anything without much trouble. Give it a go! Oh, and awesome video I've been eyeing one of these for a while now and your video will be super helpful in my purchase!

@timsmith6815 4 жыл бұрын

Glad I found this channel great videos with just the right amount of info and detail. I got a K40 about 4 months ago, was from an ebay seller that shipped from California. I was very lucky my unit worked perfectly out of the box, I did tighten every cable nut bolt etc etc. 4 things I want to tell people. 1. My exhaust goes into a bathroom vent I installed in my garage, its right behind the unit so vent length is only like 2 feet, I sealed the fan and K40 tightly so air can only come in thru the vents in the front cover and exhaust out the back. If you seal the unit and have a short exhaust run air assist isn't needed. When I print the air flows so quickly over the piece I am working on and out the exhaust the smoke is instantly pulled 90 degrees away from the laser output. Smoke has never gotten close to my mirrors. 2. Cooling. The included pump and bucket idea is horrible, my laser is in the a garage in Nebraska so printing in a garage that in the summer can be 35C will not work, sure you can do the ice cube thing but thats a pain. Perfect solution is a Chili Cube from Chilipad, this company has a chilled mattress pad for you bed that uses Peltier cooling. You can get just the Chili cube on ebay for $75-100 usually. This simply works perfectly for the K40, I insulated the hoses and both ends on the laser tube as best as I could and the results are amazing, plus it look nice and clean. On a hot summer day say 29C in the garage turn on the unit in about 10 mins the K40 is chilled to about 17C and it hold's that temp while printing. Very happy with the results. I do have some RV antifreeze in the water to keep it from freezing in the winter and that works fine also. 3. Check your ground connections and clean them, they clamp the cables to a painted surface, sand to the bare metal and tighten. 4. For now my control board is fine it does everything I ask it to do, I may update to a Cohesion3D LaserBoard but for now I have no reason to. hope someone finds this info useful

@TerryFrenchy 4 жыл бұрын

Hi Tim, what do you use to connect to the output of the chili cube? Do you use their drain plugs? It's unclear what fits there, and the company only sells some "drain plugs" for $5 or so. I'm very interested but wonder how to make some hose connection to the cube. thanks

I was unsure if my K40 was a clone or not, thus having an inferior viewing port, ( among other things ). The glasses also help protect my eyes when using my Diode cutters. I've thrown a Mini "Gerbil" 2 Axis Controller which is made right here in Australia. So it gives me instant axis to Lightburn. Good vid

Thanks a lot for this video. This is what I needed to see. The amount of work needed to balance out the shoddy workmanship, along with the very real safety concerns makes this a bridge too far for me.

Make sure whatever you're using for coolant is anti-algae and non-corrosive. you don't want any growth nor do want your coolant eating away the metal pipes in your cooling system. If you live in a really cold place you'll also need anti-freeze or your tube will burst. if you live in a hot place you'll need refrigerated cooling. in this case units like the CW-3000 only blow air on a radiator. the CW-5000 refrigerates the coolant, but it's super expensive and not worth the price. I live in Australia and the summer heat can get as high as 47deg C or 116 deg F, the solution that worked for me was getting an aquarium chiller like the Heilea HC100A that can chill 100 litres of water, low noise and way cheaper than the CW-5000

Hey michael nice to see you getting into lasers, You should need nowhere need 20+ma to cut! When i first started i thought i needed it aswell but that means something is out of focus or your lens is dirty. I now cut through 3mm plywood at 10ma sometimes even 5ma if i go slow enough. The lower you keep your laser power the longer it will last you. Rule of thumb is pretty much never need to go over 10ma. good luck with your upgrades! :)

@TeachingTech 4 жыл бұрын

I think for a k40 10ma is very reasonable but for my 80 (90?) Watt tube it's barely scratching the potential. I agree on the life but I'm already running it 3ma under the safe level from the manufacturer.

As for the safety advice, unplugging from the wall is something that I don’t advise as it separates the cutter from the ground. I made the unfortunate mistake while changing the laser tube in a k40 of unplugging the cutter from the wall, thinking it would enhance my safety. When I cut the red wire to the laser tube to replace it, it shocked me like I’d never been shocked before from the charge remaining in the power supply.

@TerryFrenchy 4 жыл бұрын

you have 2 things. keep the ground connected can help, but you need to check that the ground is still connected when the switch is off. Like with any power supply, what you need is to give it a chance to discharge its capacitors. 2 ways: let it be for a DAY or 2. (no guarantee, but pretty good), and/or use a "chicken stick". google "chicken stick discharge" as the keywords. Basically you want to go poke at any high voltage wire with a "stick" that has a path to ground. Force grounding the leftover voltage in the power supply.

I would like to add something. MAKE SURE THE AXIS IS SQUARE!! When I bought mine the cuts weren't square, and when I cut something, then flip over to cut or engrave the other side, it would not match up. Your laser may be slightly out of square, probably knocked out of square during shipping. So check it with a square. The solution to this problem is to gently hit the out of square part with a rubber mallet to knock it back into square. Then burn a square and check to make sure they are square. This is probably less of a problem for linear rails...

Hi Michael -- Like you, I have recently purchased a Chinese laser cutter, in my case it is a 600x400mm unit with motorized Z-axis. I got it from a dealer in California (name withheld) who is really nothing more than a middle-man -- they are useless for information or help. The unit I got claims to be 100W, with the W2 Reci tube. After I added a ma meter I found that I needed to limit the power to 58% or less to keep it under the suggested 25ma value. It's unfortunate that these machines are designed to easily overdrive the tubes, and without an ammeter (not included) uninformed users will likely burn them out very quickly. My unit has the Ruida controller, and I am using Lightburn (a great program). Through Lightburn it was easy to make settings in the machine's firmware to limit the power to 58%, no matter what the user requests. I also designed my own rotary axis, and modified the machine's wiring to allow rapid plug-replacement of the Y-axis motor (with power off of course). BTW I put the rotary design up on Thingiverse, it's available open-source: www.thingiverse.com/thing:3906379. Many thanks for a great video, and wishing you well -- Neil

My Linux laptop went just fine, but Windows sucks at connecting to anything... Half the time I have so many workarounds like software emulating Xbox controllers on game pads to faking drivers when using Windows. Thankfully on Linux everything I’ve ever connected has just worked. From Android phones to IPhones without ever installing iTunes garbage, to windows machines and bridging networking connections etc to basically you name it like flight controllers, Linux has always just worked. Same software, same settings, same baud rates and everything, but for who knows what reason the much new top of the model line (and upgraded on top of that) with the most popular desktop OS on Earth just can’t compete vs my trusty old 2012 duel core Linux laptop because it works for everything. (And I really don’t get it, because I’ve programmed arduinos and stuff on the Windows machine, so it does have COM port drivers working etc)

I think you should've asked the seller to replace this control board for you even though you'll use something else at some point.

I started with that little pump, and ended up getting a much, much bigger one, it does seem to be the more air assist the better, but a poor tubing setup can really affect the flow.

I have to admit, I was not expecting the CNC focused seller's website to also sell stripper poles.

Hi, thanks for the detailed review. I only want to engrave leather. Would this machine be overkill? Do you know what kind of output power is required just for leather? Thank you

Great info thanks, are you still satisfied with your lazer?

Thanks so much for this! I got a solid state laser for my 3D printer and I've been having a blast but I already want to upgrade! I'm stuck between trying to build my own 5.5W solid state laser engraver or buying a CO2 laser cutter. I would build my own CO2 cutter but it seems very difficult to purchase a CO2 laser tube on its own.

I'm trying to do the same thing to my homemade 3d printer. I printed a mount and put a standard spindle that is just not powerful enough. I have a "20 w" laser engraver but its just not powerful enough. I wouldnt mind having that on my 24×24 " printer tho can you suggest a good place to buy a little more powerful laser than those Chinese 20w. And how are you making the file so the printer understands it is using a lazer and not 3d printing

I bought one and the biggest lesson I learned was about import tariffs... In the end, I spent almost 2k in taxes and duties... make sure to figure that in, or you will be screwed.

I watched your mpcnc lowrider videos and they were really helpful in building mine thanx alot. I was intending to use it as a laser cutter by combining two 20w laser with a cube lense but that seams to be unuseful idea. So, do you think I can use a co2 laser with the mpcnc lowrider machine?

Really good video. As an Aussie can you link me to the seller you used on gumtree? You clearly seem to have had a good experience. Also I saw you insulate with hot glue. You can get liquid electrical tape for future projects from your local Jaycar
