First Things i did: Ampmeter installed. Added foamtape to all lids to prevent uncontrolled airflow and Fumes. Added 4 40mm holes to small front lid to make sure all Air is sucked in here. Closed all unneccessary holes with ductape. Closed Back of top Cover with ductape. Added flowmeter in waterhose. Realigned all mirrors. Leveled the bed as good as possible. Glued the bed to the frame to prevent wobbling. Added 3d printed crank for z movement. Added 7812 stepdown converter circuit to add 12v Led strips and future 12v parts. Chassis Part there the lasertube ist screwed on vibrates a Lot - fixed with 3d printed angle.
Eric, Air assist is NOT a flame extinguisher. The air assist actually adds oxygen to the fire and while it may help blow it out, that's not what it's for. Air assist is to help clear the soot and other particulate from the cutting area. I only have a K40 so mine is probably not even 40 watts but from the Facebook group I belong to (Laser Engraving and Cutting) they seem to suggest getting a proper watter chiller (helps keep the water going into the tube cool, if the water going in is too hot, cutting power is reduced and it wears out the tube) For the exhaust fan, I ended up getting a furnace blower fan and rigging it up, got it for free, and it's super quiet on low speed and not terribly loud on high.
@@EricStrebel No Worries, it happens. Just didn't want people to think that if they got "Air Assist" that they could leave their lasers unattended while they were running (Which is a huge no-no no matter how comfortable you are with it, or how good of a machine it is)
Congrats on your recent purchase, man! I've had my machine for about four years now, and it has certainly paid for itself several times over. My experience was that I used to go to a MakerSpace local to me here in Los Angeles, and went with the initial intention of 3D printing a few things, but each time I went, the printers were always down. Since they had a laser cutter as well, I inevitably kept using that instead, and became a big fan- to the point at which I bought my own machine. Prior to this, I had always known about Epilogue, which makes fantastic machines, but waayy too expensive. I ended up getting mine directly from a manufacturer in China - a 100 watt (no brand name) machine with a 2x3 foot bed. I feel I got a better machine for my money, though one problem is the lack of support, so the troubleshooting is completely on me. Also, it has a dongle for the motion controller, so if I lose that guy, I'm hosed as well. Would pretty much have to switch it out to a different one. A few thoughts from watching the video: - I ended up buying a dust blower from Harbor Freight. The blower that originally came with mine was 220v, but when it crapped out, I went looking for a replacement, and everything was super spendy. I just made a little box to support it, and have it going through a vent directly leading to my alleyway. I would buy a carbon filter/scrubber unit, but like you mentioned, they're pretty expensive. - For the temperature gauge, I bought one of these: www.aliexpress.com/item/1PCS-W1209-DC-12V-heat-cool-temp-thermostat-temperature-control-switch-temperature-controller-thermometer-thermo-controller/32713892704.html?spm=a2g0o.productlist.0.0.3258a9c01wlJGS&algo_pvid=6572c02b-dc23-462e-b0f1-5a3da51ddd70&algo_expid=6572c02b-dc23-462e-b0f1-5a3da51ddd70-3&btsid=9447691b-6663-46bf-a37b-60b5b95e6ad5&ws_ab_test=searchweb0_0,searchweb201602_1,searchweb201603_53 I then connected the relay to an alarm, so that when it hits a certain temperature that I don't want to exceed, it triggers it. This sensor goes directly into my water return bucket. - On the subject of your cooling tank, I was always told to use purified water, as the minerals can start to form deposits inside the tube. While my water tank is usually "less than ideal" (dust and debris sometimes make their way in), I have never had an issue. That said, I'm not sure if antifreeze is okay to use or not. Just a thought. -Last, something that commonly happens on my machine, and I don't know if you have experience it yet (or have the function on yours), but if your water pump isn't circulating/operational, it may cause your machine to appear broken (you go to fire, and the laser doesn't function). I mention this as a couple weeks back I was taking my machine apart, and getting ready to buy a new laser tube, when I checked the pump one last time. Saved me $700 bucks. Thanks for posting the video, and I look forward to seeing all the awesome stuff you make with it!
good advice, but if you wanna get started in lasering right away, dont hesitate with the 40w. just know that youre going to outgrow it super fast. also air assist is easy to add. and it's definitely important to save you from fires.
One of the first things I did when my 80w arrived was to check the optics, you’ll find they’ll be grimy with oil residue from transport and storage. Also cleaned off all the excess grease on slides and swarf in the bottom. Like you I love my laser cutter :D
@@EricStrebel Hi Eric. I got the parts from here: www.lightobject.com/K40-Upgrade-Parts Specifically, the focusing lens is Part #: LSR-ZNSE1838HQ The reflecting mirrors are Part #: LSR-MIR25MSI Hope that helps. Cheers...
@@EricStrebel The new optics gave me a smaller spot size and less burning and charring around the cut (kerf) at the bottom end of the power range. There was a slight power increase, in that I could get the laser to cut at about an 8-9% reduction in laser power at the very low end. This could also allow for slightly faster cutting speed at the same laser power, but that's not really what I was after. The goal in changing out the optics was to get the laser to cut with the smallest spot size possible (narrowest kerf possible), in very thin material (adhesive backed paper). The new optics gave slightly more power at 11-12%, with a "cleaner" beam/spot. The OEM mirrors and focusing lens were just awful on my machine. Not sure if everyone else had a similar experience. My focusing lens was particularly bad. It was very cloudy, which for CO2 based lasers, is not desirable. All in all... I'm mostly happy with the machine. The mechanics are pretty good. The control is functional. The laser is pretty crappy though. Beam quality sucks and gets worse as you go up toward the limit in laser power. When the laser tube starts to degrade, I'm going to replace the laser and power supply with a higher end unit, provided the mechanics are still in good shape.
Eric you are very lucky to have found a good one on ebay. I have bought a 40 W and it tanked in less than 2 months. I bought a 60W monster and it was DOA. BTW only on ebay do you have to pay for that lift. I paid $150 so they could just leave the 60W in my driveway. 375 pounds!! And after I sent it back they did not refund me for something that was not my fault, they damaged it(the freight carrier). And I had to go through ebay to get the seller to return my money for the laser($2349)! I just bought an Orion 50W from a reputable affiliate(Yes REPUTABLE) and no other charge to deliver to home or anywhere else and I paid $1399 for it and added the 3 year warranty for another $58. Yes a warranty! Orion does not sell their lasers on Ebay. What does that tell you? I would not advise buying expensive items on ebay. You might get lucky but you are more likely to get shafted. I think they are rejects and they buy a lot of them for cheap and fix them up and sell them. The 2 that I bought had a lot of flaws.
Perhaps I got lucky, but I do totally expect parts of the laser to fail at some point. At some point the laser itself will fail and the tube will be replaced with a higher wattage one
Eric, you want to change the automotive coolant for demineralized water as soon as possible. Automotive coolant is self cleaning, that means a bit abrasive. On the other hand, water shows better when it's time to be changed.
My idea is to build my own, that way I get all the features I want and I am not limited to some manufacturer. Plus I have the freedom to get a more powerful laser down the road and just plug it into the build.
wow thanks, I needed that, just sent BACK a flux beambox pro, lots of issues. the time I spent trying to get it to work, I could have spent upgrading one of these!
A laser is a useful too. I would suggest checking your local makerspace/hacerspace first. Just like 3D printers it's a useful tool but will need to make a lot to make it worth your while. If you still need one at home/in the shop you et least learned a few tricks. I've played with lightburn. It's a good piece of software. Not freeware but worth the price. Depending on what you want to make opt for a draw tool with a coordinate system. I'm struggling quite a bit with inkscape as it all approximate and not exact. From past experience at my local hackerspace (Bitlair) I suggest investing in chiller for the water. Chilling the tube to 20 degrees C will increase the live of the tube considerably. Note: The guys at Bitlair build the lasercutters from scratch, It's about €3k each. (Chinese import would be €2k). (Note: Everything is more expensive in Europe.)
Thanks for the video. My eyebrows went up a bit when the hole saw went into your machine! Looks like the Amazon link is unavailable at this time. Got an eBay recommendation? Also, what is the maximum material thickness you can cut?
I've always been toying with the idea of getting one for model making and yet wary at the same time. People claim there's a risk of styrene catching fire or damaging the hardware over time even if there's an air assist and ventilation and some people claim thin copper sheets work (as a quick alternative to photo etching model kit parts), while others claim it doesn't.
Hello. 6040 50w china. What is the maximum thikness you can cut acrylic you can cut, with one or more pass to have reasonable good edge? Is it good to do more then one pass? (10-15mm) thx
You showed in the video using antifreeze for cooling. I’m looking to purchase a unit. I live in Wisconsin and i would need to keep the laser in my garage. Two part question. Will the cold otherwise damage or hurt any laser Machine? And Any pros, cons, mods (other than price) to using antifreeze over distilled water? Lastly, I am looking to get the Orion Motor Tech 50w or Preenex version Orion appears to come from Orion Motor Tech Direct., and the Preenex from a warehouse in Memphis on Ebay. The Preenex is allot cheaper than the Orion. You mentioned a buying from a US seller. Would I have any issues from these two chinese machine, or do you have another recommendation under the $2k mark.
I suspect the cold won't hurt it, however there is liquid use to cool the machine. I used a mixture of distilled water and anti freeze. Water expands when it freezes so I would be wary of leaving it in a place that is not temperature controlled. I only have experience with my machine, so I can't comment on there two machines you mentioned. Check the reviews and ask other people that have owned them for better feedback. Best of luck!
This looks incredibly similar to some of the laser cutters I've run. Any chance it has a Ruida controller? I was going to see if you mentioned LightBurn, and lo and behold!
Hi Erick! I just bought a 50W laser machine like yours on ebay, but I having a hard time to find acrylic plates larger then 24" X12", I'm interested in make signs, do you know a supplier? I'm in Boston, and thanks for the video.
Lots of great info I hadn't though about. I'm currently playing with a 7 watt laser on my CNC machine. I works great for cutting paper, cardboard and 3/32" basswood. The engraving is really good too. The main problem with it ...... Sooo Slow to cut the 3/32 basswood. I have cut, "burned" through .145" plywood with about 6 passes at 3 ipm each. So I have been watching videos trying to collect enough info and personal uses for a brand of laser I don't have to fix after delivered and decent service after the sale. While looking through you links I assumed this was the one you bought..(Buy a 50W laser: amzn.to/30hK9kR ) Unfortunately that link didn't work. Thanks for the great information!!
Thanks for sharing, Eric. I'll post a link to your video in the Shop Hacks Facebook group here... facebook.com/groups/shophacks/permalink/437467873488107/ I have a Glowforge but I'm very interested in the Chinese lasers because I think they are within reach of a lot more people than the US brands.

Well it will not cut metal, but I do see evidence of light scoring on some metals. I think it will definitely depend on the power of the laser.
Even most videos using professional lasers on thin copper sheets use at least twenty passes, so that doesn't surprise me.
