The only thing you need to change is the limit switch of the X-axis. Since I have a 3-D printer and I am proficient with Fusion 360 I would really appreciate getting your Digital files. The frame was assembled using 3D printed pieces. In the winter, everything was simple with cooling, but summer is coming, and I’ll have to figure something out, I recommend buying chiller system CW3000 will be enough for 80w laser, there are also few options, chiller for a beer, used one cost starts from 100$, the second option is reassembled air conditioner. Just to make it clear let me explain how this type of CNC machines works, we have an rectangle aluminum frame, guides are installed on both sides parallel to each other, and a crossbar with a guide. I use a 800 l per min Chinese water pump for cooling, which I certainly don’t believe, but a fact that it works fine and it's silent. This device reads the codes from your computer (or raspberry pi with touchscreen) and converts them into pulses for the steppermotor drivers and laser driver. Glad you liked my cnc machine, I will be glad to answer any questions! My son completed a safety monitoring board that keeps track of coolant, laser and enclosure temperature as well as the state of a door switch. With two extensions for generating the G-codes. In 2013 I built one of the first blackTooth DIY laser cutters from BuildYourCNC. The High-Ten Upgraded Version CO2 is a really capable laser cutter for those on a budget. I think so, especially considering that the design does not require such special rigidity as let's say milling cnc, there are a small mirror and a lens are wound from side to side and not a 20kg piece of steel. Normal lasercutters use the upper left corner, but this doesn't really change anything on the quality of your cuts, so the lower left corner of the working area will be used as home position. He owes me aluminum skins, waiting for his local maker space to come out of Covid restrictions. Use crtl-F to find 'homing' and search until you find "#define HOMING_INIT_LOCK". The upper space is the space where the laser wil come. But as always there is an alternative way, GRBL, in fact it is a great platform and it works just fine, but with some reservations, we are not using a weak laser diode, but a freaking 40W CO2 tube that you can cut off your finger, so if we engraving on wood or acrylic we will find out such a thing that when you try to increase the speed more than about 5000 mm per minute, the laser does not go faster, at the beginning of the work it seemed to me good enough. Hello! As this lasercutter uses a 40 W CO2 laser, it is obvious that the laser beam and even reflections of it(!) I’ve looked at many, many different designs and I really like what you have done and how you have Provided so many details on how to make it. If you don't own a 3D-printer and don't know anyone with a printer, you don't have to buy one yourself. If you do it wrong, you'll lose the little balls of the bearing and this would be very annoying. or Best Offer. Which way did you end up going with the Y-axis? In the names of the files, I mentioned the thickness, the material, the color and the quantity of the plates. The total costs for this awesome lasercutter are about €1900. Thanks, ChuckPS, by reviewing your Fusion 360 design, I have learned a lot of features that I did not realize was capable within Fusion 360. So you'll need to repeat this several times with a new piece of wood. diy co2 laser cutter help to improve the accuracy and precision of the laser equipment machines. We replaced it with a CloudRay unit from Amazon and the PWM works much better now (other supply seemed to run at too high a voltage for the 40w tube (28KV vs 22KV (startup, 10KV running). I'd love to compare the prestations of this lasercutter to a professional one. I was wondering if you have done any Fusion 360 design work on using rollers on your design? I'm not responsible for eventual accidents. We also used a grid bed rather than the MDF, the cost was not that bad and it is way cleaner. Thanks! To mount those parts, just look at the pictures how I did it, I think this is the easiest way to explain it. We also need an 18 mm MDF sheet as the base for the working area. In vector mode, the contour of an object will be cut or engraved. Hello! The names of the parts are written in Dutch, sorry for that, but normally this shouldn't be a problem. Now I will explain the basic design of this project. You can just use a 3D-printing service like 3D hubs, it's very easy. One problem was that lasercutters aren't cheap, especially not for hobbyists who want a large cutting area. Share it with us! I've got a key switch override for the door switch to adjust mirrors. 119. I've already made tons of key rings, greyscale pictures, boxes, birthday cards and even a simple duck! I uploaded a video of this lasercutter on youtube, you can find it here: In this step, I will talk about the design of this machine. #define HOMING_CYCLE_1 ((1...X_AXIS)|(1...Y_AXIS)) ", Comment this line. " I mounted the power supplies, arduino, stepper motor drivers, and relays on a plate, this makes it easy to work on it. 1 day ago. The x-axis is fastened with 30 mm m6 bolts, I made the thread in the profile. The laser will have marked another dot on the wooden piece. Lasers with an output of 5.6 watt, 8 watt can engrave on anodized and painted aluminum, glass and stone. 2. Important! 4 weeks ago. I've also build one of these, works great for etching glasses and mugs (https://geeksmithing.com/rotary/). You'll see, this is very easy and only takes 15 minutes of your time. It will be on my to do list I have 4 3d printers, so when I begin I can run multiple prints at the same time. Thanks to a handy USB port, it's easy to get projects onto this machine that can cut at a rate of 3600mm per minute on its 400 x 600 mm cutting plate. All manual safety and temp monitoring at this point. A lasercutter works with Gcodes. DIY 100 Watt CO2 Laser Cutter. diy co2 laser cutter basically complete your laser equipment, enabling proficient working of your devices. We enclosed the frame with hardboard and Acrylic (using the cutter to handle the Acrylic). by: James Hobson. Can you please clarify that? This is project How To Do, and my name is Konstantin. First of all, you need to install the latest version of the arduino IDE on your computer if you don't have it already. When that's done, open the arduino IDE again and open the serial monitor (right upper corner). First set the baud rate to 115200 and type '$$'. Also, between the profiles and every plate of the ventilation area, i glued an 'air strip' (I don't know how you call it in English, but we call it 'tochtstrip'), you can see it in the pictures. The right side of the laser (ground end, and output end) exits into the radiator then back into the tank. The machine requires ventilation of the working surface, I bought such a 20-watt fan and, as it were, it pulls absolutely nothing, you need a powerful turbine. As usual, I've made a complete bill of materials with everything you need to build your own lasercutter. 5 weeks ago, Hi not forgot just got lots on at work sorry, Just some pictures of my laser cutter build. On the top I put a polycarbonate sheet, laser ray can't pass this material, so you shouldn't be afraid to stare at it through the lid. If you chose to assemble controller on grbl, like me, then everything is as simple as possible, google Arduino nano grbl and solder everything according to the circuit, there are literally ten wires, connection to the laser power supply looks like this. First one in line: safety! My system has a separate 12v 400w power supply, it was supposed to be for the cooling system on the Peltier modules, but it didn't work well, maybe I will continue experiments later, at the moment this unit powers the air pump to blow the working surface. BobsCNC knows a thing or two about making these types … Thanks, Chuck, Hi KonstantinThe link you provided made it simple to download your Fusion 360 file and load it on my computer.I must say this is the most comprehensive 360 file that I have worked with. It works great! I included the full wiring diagram for all the drivers and microcontrollers, the best way to wire them is to print the diagram and just mark which wires you already connected, so you'll know what you've already done. It will be cheaper and easier to bend the plates. Remember that the laser itself will only work when the pump is activated and the cover is closed. The entire project cost me about €1900, this is still a lot of money, but I didn't want to make it from scrap. But now this is a real limitation, engraving takes the longest time and you can reduce it by slightly increasing power and significantly increasing speed. need to be kept inside the machine. 10 months ago, hi hows laser cutter coming on have you seen mine so far. All mounts for mirrors are made for 20mm and have adjustment, between their base and mount itself I put cropped springs from gel pens, for ease of adjustment. Stepper motors are simple nema17 with a 5mm shaft. This makes it possible for your computer to recognise the arduino and compile GRBL to it. There are two power supplies, one 12 V for the fans, pump and motors and one 5 V supply that powers the microcontrollers. Why build a small machine when you can build a big one?Since this is still a DIY machine, I wanted it to be easy to change or add parts when needed. In my case, it took 2 sticks of 840 mm, 2 of 700 mm and one of 800 mm, to connect the profile using special angles and nuts. The laser beam has a carving accuracy of 0.05 mm and a wavelength of 405 mm. You can really make anything you want! I just spent a total of circa €350 on those plates. Since we are in the kitchen, let’s take a look at these laser engraved glass spice … Austin Waterjet offers advanced laser cutting services that can be used for a variety of applications, including architectural ornaments, HVAC, sheet metal fabrication, and signs. I keep separate speed and scale values in lightBurn's console to switch between the normal Y axis and the rotory. It's best to do this before mounting the plates because you have easy access to everything now. 30W 110V Fiber Laser Marking Machine Metal Engraving Engraver High Precision . The water will be pumped from the tank to the laser, to copper pipes for cooling the water and then back into the tank. I have a few questions about it, though perhaps too many for a discussion here. The colour of the parts doesn't really matter, but I printed all of the inner parts in red (because we liked it) and the exterior parts in black (and some inner parts, just because I ran out of red filament ;)). Glowforge Plus 3D Laser Printer. Let’s dig into the nitty-gritty. For the copper pipes, i bought three 12 mm copper pipes of 1 m together with two female to female elbows and two male to female elbows and just soldered them like you can see on the picture. I had access to a circular saw and a belt sander, so cutting the profiles was a pretty easy job, but it still took a day's work for two people. Makes it easy to see when you are going to fast, or don't have enough power for the cut. More by the author: ... Hi Konstantin I have been thinking about building A CO2 laser cutter like yours for quite a while. 39 Comments . The files with the dimensions of the bevel are also included in this step. If so do you have any Fusion 360 designs? The one for the x-axis can be set on 1,8A. I included the .dxf files of all of the plates that have to be cut for the lasercutter in this step. Thanks for watching/reading, see you very soon! I also have my blower pulling from under the honeycomb. The stepper motor drivers are set on 16 microsteps, this means that every step of the motors is divided in 16 seperate steps. I started to look on aliexpress, cheapest I found is about 400 dollars, for that price you'll get working aria of 300 by 200mm, and it looks funny, my 3d printer has larger table. A very important point, the laser tube needs to be cooled at its operating temperature in about of 17 degrees Celsius, less is good - even power will increase, but if temperature rise above 17 degrees Celsius it will damage your laser or shorten the life time of it. The last element of the optical system is the lens, it come in different focal lengths from 38.1mm to 101.6mm, if you imagine how the beam goes, than you can understand the difference of usage, lenses with a short focus are mainly used for engraving, and long focus for cutting because the area of the beam with a high concentration will be larger and the material can be burned deeper. As already mentioned 90% of the mechanics were printed on a 3D printer, the filling is 100%, I recommend to buy if you don't have 0.8mm nozzle so that printing goes faster. Once you have a machine like this, the sky is the limit! The parts list doesn't show couplers for the Y-axis motor. I don't really know how many of them I used but the quantity I mentioned will certainly do. In any case, in addition to the brain, you will need drivers for stepper motors, I used TMC2208, I thought that I would use 256 microsteps and I would make 10000 lines per 1 mm, but as you can see the controller just can't handle it and I recommend you to do not overpay and buy the classics A4988 and everything will be fine. Just added a few samples of stuff made to date. You can also import files like .svg, .dxf, .jpeg... For sending the G-codes to the arduino, LaserGRBL is being used. 8 months ago I also want to go through the points that can be improved, as I said about controller, I ordered several different boards, I will test them and show everything on this topic. I realized that I need a cnc Laser, but not a simple one, I need a powerful CO2 laser! Two of these sheets need to be bent to fit the bezel, I contacted a local company for this. The arduino is just connected to the steppermotor drivers and the driver of the CO2 laser. RC Arduino Domino Layer With Bluetooth App Control. That was so amusing. Of course, after engraving with a 3D printer with a maximum speed of 400mm per minute. Thanks. I've since moved to a CW-3000 cooling system. There are dozens of methods in use around the world, everything from minimal cost low tech home brew solutions to high priced commercial chillers. CO2-laser cutting acrylic: Fiber Laser Cutter for Metal Fiber laser cutter is used for cutting stainless steel, carbon steel, electrical steel, galvanized steel, aluminum zinc plate, aluminum, aluminum alloy, titanium alloy, copper, brass, iron and other metal materials. But i have still problems with shutting down the raspberry PI 3. Plus, for this price, you get an awesome experience of building your own lasercutter and invaluable knowledge. I also made the cutting bed from aluminium honeycomb that comes flat then you open it out to the desired length I will be using a pc water cooling Radiators 2x360 and 2X 400 water res I’m also having a Dallas water temp sensor followed by flow sensor I can’t wait to finish it My email is designlab2020@outlook.com be good to send pics over of work progress and a video of it working, HAVE YOU GOT PIC OF ALL THE INSIDE AND THE LASER WITH THE COOLING SYSTEMS PLEASE. Basic I'm trying to change the background picture on the display.. Any pointers would be greatly appreciated...Thanks, Answer It really works quite well. When the laser is calibrated correctly and everything is tested, the last plates can be mounted on the construction. It makes sense to buy an aluminum profile at the local store. I 3D printed some adapters to convert a 4" dryer hose to two 2" ducts with flappers through the wall behind the unit. I already purchased all the components however realised its missing the 3d files, without them I guess not only me, but most of us are just lost :), Reply Chuck. It also does some safety checks before turning on the laser. I advise you to simply buy a power supply for your laser from China, its cost around 40 bucks. I carefully mount the aluminum frame on the printed brackets. This is a full step by step instruction on how to build your own lasercutter! In my school, we have a cnc miller, so the plates were cut by one of my teachers. The plate is just transparant enough for you to see what happens inside. Item specifics Upgraded 40W CO2 Laser Engraver Cutter Cutting Machine Craft USB 8" × 12" DIY This 40W laser engraving machine with 12” x 8” working area is great for almost any smooth surface (except metal) and has red dot guidance to make even more precise engravings. Engraving is available on wood, acrylic, and other non-metal, non-pvc surfaces, except glass. And now I have a question for you, why the cost of the machine will differ significantly depending on the working aria? Like I said, a work in progress! It is recommended to use distilled water as a coolant, I use an anti-freeze, the option is so-so, many people criticize it, but in the garage in the winter the temperatures drop far below 0 and the laser would just burst with ice. Building custom machinery with the specific needs of our shop and client base is a passion of ours. A lot of the parts of this lasercutter are made with the help of my 3D-printer. I feed motors with a voltage of 24v with such an power supply, it also feeds a water pump. See more ideas about co2 laser, laser cutter projects, laser.
