The laser is powered by a high voltage of thousands of volts, you have to be very careful when working with. Once you have a machine like this, the sky is the limit! You can see some of these parts in the image, but not all of them are included there. Still just the fiberboard enclosure, but it's working great. To assemble the profile, just start by assembling the bottom profiles, then the vertical profiles, the upper ones and last of all the middle profiles. In the BOM, the individual plates aren't mentioned because you'll get more information about them in step 7. The tools needed for this are actually just a metal saw. See more ideas about laser cutter, laser, co2 laser. You can really make anything you want! The arduino is just connected to the steppermotor drivers and the driver of the CO2 laser.

It's great. A lasercutter works with Gcodes. Laser Components. Also moved to a submerged water pump in the tank (way lower power, and less vibration). If you don't own a 3D-printer and don't know anyone with a printer, you don't have to buy one yourself. In the names of these STL-files I mentioned how many times each part needs to be printed. To design the objects that need to be cut, i use inkscape V0.91. The stepper motor drivers are set on 16 microsteps, this means that every step of the motors is divided in 16 seperate steps. 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. Now the exhaust pipe, the cooling fans for the electronics and the power plug can also be mounted on the backplate. Glad you liked my cnc machine, I will be glad to answer any questions! Four other things that need to be changed are: " #define HOMING_CYCLE_0 (1...Z_AXIS) ", Comment this line. I couldnot flash a working program on a raspberry PI 3 B + only on the raspberry PI 3. I printed all fasteners for motors, electronics, belts, lenses and other things on a 3D printer with a PETG filament, there were doubts that all this could work fine and provide good accuracy, but after a couple of months the work it's ok, even such a thing as a nozzle through which the laser passes the beam work fine. A lot of the parts of this lasercutter are made with the help of my 3D-printer. Share it with us! Extract the .zip file, go to the folder 'grbl' and open the config file with wordpad. It's mounted at the furthest point of the axis and it needs to be placed on the nearest point. Laguna Tools’ CO2 laser cutting machines include working area options of 24″ x 40″, 36″ x 52″. The entire project cost me about €1900, this is still a lot of money, but I didn't want to make it from scrap. To begin with, I recommend taking 50.8mm you can engrave and cut with it. There are two power supplies, one 12 V for the fans, pump and motors and one 5 V supply that powers the microcontrollers. I mounted almost every plate, except for the back plate and the side plate on the side of the electronics. Still not a bad option for this type of machine is ordinary rubberized rollers, as is often used on 3D printers, it is very cheap, easy to maintain and replace, and nevertheless gives sufficient quality. It is important to install grounding on the machine, it does not matter which board you choose, it is extremely important, otherwise various artifacts will creep out in the form of missing steps, freezes and other things. I just remove the tray and plug in the rotary in the "Y" axis controller.I also gave in and purchased an external cooler and ditched my home brew pump and radiator setup. I was wondering if you have done any Fusion 360 design work on using rollers on your design? As for this step, I'll just explain how and why I got to this design. I also changed the mirror holder mounted on the Y-axis, You need to mount it on the same spot, but i just changed its design to be a bit more resistant to vibrations of the axis caused by its movements. Share it with us! This will be done by watercooling. 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. Some time ago I was siting, counting my millions from YouTube, listening to cnc router noise, and decided to move on. // #define HOMING_CYCLE_1 (1...Y_AXIS) ", Uncomment this line. I absolutely intend to recreate your cutter for use in my workshop, would you mind if I sent you a private message with questions? 3.3 out of 5 stars 6. Behind the ventilation room, there are two spaces on top of each other. Before making a draft of what the machine should look like, I made a list of things that needed to be kept in mind when designing it. The construction consists of five seperate places. The names of the parts are written in Dutch, sorry for that, but normally this shouldn't be a problem. I had some stability problems when I used tap water, but once I switched to distilled water it's been 100% stable. The upper space is the space where the laser wil come. Orion Motor Tech 40W CO2 Laser Engraver Cutter with 200 x 300mm Work Area, Desktop K40 Laser Engraving Machine with Digital Control, Red Dot Pointer, Detachable Wheels, Compact for DIY Home … Since the cost of the ball bearing slider is relatively high, as you noted, I was considering using rollers as you also suggested like the ones I have on my "Delta" 3 D printer. Engraving is available on wood, acrylic, and other non-metal, non-pvc surfaces, except glass. So I decided to use an MDF sheet instead. 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 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. You can use those or buy iron pieces for extra fastness. I added two resistors to the homing circuit on the arduino. 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. The 8 mm dark acrylic sheet used for the cover needs to be cut as well. The frame was assembled using 3D printed pieces. And it's still very cheap for a lasercutter with such a large cutting area. Quickly push the testbutton on the laser driver. 54 sold. Those are all the files and programs you need for letting the lasercutter do its job. We did cooling using a radiator instead of the copper tubes, and I used a blower from a kids bouncy house for the exhaust (really works well!). With two extensions for generating the G-codes. You can see the lay-out of the electronics in the pictures. Co2 40W laser engraver is able to engrave a wide range of materials including plastic, wood, plywood, leather, glass, acrylic, rubber and so on. 21. are some commonly bought products involving laser-related uses. That way, our stepper motors will need to do 3200 steps per revolution with microsteps instead of 200. The second factor I kept in mind was how big the working area and the cutter itself would be. This is highly recommended! Here are some pics. Special warranty for an Endurance DIY laser kit. In a general system for 2 axes you will need one (1) laser tube and laser tube power supply, two (2) mirror mounts, three (3) mirrors, one laser nozzle also called laser head (where the final mirror and lens is held) and one (1) lens. And another one for raster mode. I've already made tons of key rings, greyscale pictures, boxes, birthday cards and even a simple duck! I can just pull out the bed, and the rotory unit is under it. 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. I would recommend you to use 6 or 4 mm acrylic for the cover because: 1. Now, the fans are mounted in the front of their plate and they're much more effective. It makes sense to buy an aluminum profile at the local store. need to be kept inside the machine. You'll see, this is very easy and only takes 15 minutes of your time. I also connected a 25V 1000µF capacitor on the power lines of the drivers, this prevents interferences on the power lines. The FabKit offers an all in one package for those looking for a feature full laser cutter which they can build themselves. This strip prevents the fumes to escape the ventilation room between the profiles and the plates. This cutting-edge laser allows for precise treatment levels and depths, which allows us to uniquely tailor the treatment specifically for each patient. The "..." need to be replaced with those arrows, but I can't type them here because there is probably a bug or something here. I will add those files in the steps where I talk about building or assembling the seperate parts of the lasercutter.

I was inspired by the hobby series lasercutter from Full Spectrum Laser for the exterior design of the lasercutter. Since I have a 3-D printer and I am proficient with Fusion 360 I would really appreciate getting your Digital files. ... 100W CO2 Laser Engraving Cutting Machine 900x600mm Engraver Cutter USB Disk. I keep separate speed and scale values in lightBurn's console to switch between the normal Y axis and the rotory. All the electronics that are being used are mentioned in the B.O.M., except for two resistors (825 Ohm) and two capacitors (1000µF). 6 weeks ago, Hi.. Love the cutter.. 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. 2x M3 20mm and 3x M4 20mm? In the pictures of this step, I added some drafts that show you the different views of the frame. I have around 3L of water in the system. Which way did you end up going with the Y-axis? About a year ago, I wanted to buy a CO2 lasercutter to make my workspace complete. We enclosed the frame with hardboard and Acrylic (using the cutter to handle the Acrylic). Unfortunately I don't have time at the moment to do that so for now I've just written a simple code. This way, the fans won't only extract the fumes from the working area but also cool down the coolingwater. 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. Building Giant Articulated Hands (carved From Wood for Social Distancing). You can see the direction of the water flow on the pump. I will make another video about it. Thanks for the plans/inspiration! It's best to do this before mounting the plates because you have easy access to everything now. Hi Konstantin Have you considered putting a stepper motor on the Z axis? Like I said, a work in progress! BobsCNC knows a thing or two about making these types … Your parts list shows 3 Nema17 motors, but there are only 2 in these pictures. I'm still planning on updating the raspberry to make it a stand alone device, but I can't find the time for that right now. I wanted the laser not to be in the working area because it would be bad for the laser to be in all those fumes. 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. With the laser beam cutting/engraving technology, the laser engraving machine can create excellent precision art-woksand handicrafts. In the attachments of this step I included a guide that says which profiles that need to be mounted and where. I think there are some chinese flatbed co2 laser cutters that use a tube mounted on the gantry. Hi Konstantin, I appreciate the offer, I have a question. Of course this one wouldn't be made out of MDF sheets. I really hope you like my instructable and it will help some of you building your own machine! I'm not very proficient with the raspberry pi.. I realized that I need a cnc Laser, but not a simple one, I need a powerful CO2 laser! I highly do not recommend inventing something of your own, you can certainly make a frame of some metal from the garbage dump, or with plywood, but come on, aluminum profile costs 10$ per meter. I wanted it to have a large cutting area of 600 by 1000 millimeters. He focussed on the research about lasers and cutting with a laser, because it's amazing that you can cut objects just by using light. It is pretty heavy and shipping will be expensive. 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. But i have still problems with shutting down the raspberry PI 3. The only things not included in this price are shipping costs (a total of about €50) and the 3D printer filament. 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. This allows you to create highly precise engravings in a short amount of time. 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. One problem was that lasercutters aren't cheap, especially not for hobbyists who want a large cutting area. For the last mirror, the one that leads the beam downwards into the lens, I just adjusted the mirror until the beam was perfectly vertical. It will be cheaper and easier to bend the plates. It needed to be built from high quality materials so it … 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. For that we need a Gcode interpreter. About 17% of these are Laser Cutting Machines, 34% are Laser Engraving Machines. I took good precautions when designing the enclosure and the laser will be only activated when the cover is closed. Change it to "// #define HOMING_INIT_LOCK". Now the electronics and the software is done, we are almost ready to use the lasercutter. Two of these sheets need to be bent to fit the bezel, I contacted a local company for this.

Hello! The cost of components changes slightly, aluminum profile cost about 10 dollars per meter, even if you take the rail guides, it will cost about 40 dollars per meter, and if you assemble it with the rubber rollers, there will be no increase in the cost of construction, all other components remain the same, the same mirrors, the same motors, the same laser. 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. When the laser is calibrated correctly and everything is tested, the last plates can be mounted on the construction. Allways use safety goggles when testing the laser. Then we move to the laser, here I chose a 40-watt tube, I ordered it from aliexpress, delivered pretty fast and everything was fine, so do not be afraid to order, after some time, I would probably take a more powerful tube, probably 80w, this will allow you to cut plywood up to 10mm, and maybe thicker, with a 40W laser you can cut materials in the about of 4mm, then you have to lower the speed and increase the power, which will negatively affect the life of the tube. More by the author: ... Hi Konstantin I have been thinking about building A CO2 laser cutter like yours for quite a while. In a C02 laser cutter, light is produced when electricity runs through a gas-filled tube with mirrors at both ends. Fix the second mirror, now get hit in the center of head, in the four corners of the machine and in the center of the working aria, the last mirror shoots down, I put the regular mirror below so that the tape can be seen and on the maximum extended nozzle I get hit in the center, it sounds like a pain in a butt, but in fact, I dealt with this in a couple of hours, you have to do it only once. I built a tank that is below the Laser tube from a 3" PVC pipe (water). Most of the items were bought in China and there is a complete list with links , for example were purchased, guides, nuts, motors, lenses, mirrors, power supplies, a laser, a cooling pump. As usual, I've made a complete bill of materials with everything you need to build your own lasercutter. Would you mind sending off the 3d files too? A 3D printer is a beautiful investment though. Did you make this project? Also, be very (!) To do this, take a piece of wood or cardboard or something and stick it with double sided tape on the second mirror (the one that moves along with the Y-axis). Makes it easy to see when you are going to fast, or don't have enough power for the cut. This is a full step by step instruction on how to build your own lasercutter! Building custom machinery with the specific needs of our shop and client base is a passion of ours. This makes it possible for your computer to recognise the arduino and compile GRBL to it. If you want more information on what all those numbers are, check out this page. SanaLoma Laser is a provider of laser engraving and cutting services using an Epilog Mini 24 - 40 and 60 watt CO2 lasers. Yes, of course, I am ready to answer questions, Question (Add "//" at the beginning of the line). " You can just use a 3D-printing service like 3D hubs, it's very easy. Looking for Custom designed CNC Equipment for business? So you'll need to repeat this several times with a new piece of wood. The results are VERY impressive. I advise you to simply buy a power supply for your laser from China, its cost around 40 bucks. This machine uses a 40W laser! The files with the dimensions of the bevel are also included in this step. Than I notice something interesting, for all additional 10cm of working aria, you will pay about 100 dollars. It's cheaper if you need to buy them at full price. We also used a grid bed rather than the MDF, the cost was not that bad and it is way cleaner. Glass Spice Jars. These mirrors guide the laser beam into the material that is to be cut. 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. I noted the Yoda in a surgical mask. The aim is that the two dots are perfectly on the same spot. 2 months ago. This is project How To Do, and my name is Konstantin. The Acrylic blocks unfocused energy from the laser pretty well, but we still always wear eye protection (with spare pairs for onlookers). Modified my tray to make it removable and added a rotary attachment to etch glasses and mugs (works great!). For now, I have only written a simple piece of code for the raspberry pi with four pushbuttons to control the lights and other functions. Use crtl-F to find 'homing' and search until you find "#define HOMING_INIT_LOCK". Since we are in the kitchen, let’s take a look at these laser engraved glass spice … However, there seems to be a solution, there are grbl options for Arduino Mega2560 boards, for ESP32 and STM32f103, in the future I’ll do a separate video about controllers, just know that arduino nano is 8bit controller but on 32-bit systems you can increase the speed up to 4 times, which is comparable to industrial boards, there are also options with displays and memory cards. The seperate spaces will be seperated by 3 mm acrylic. (see post 1 year ago). Right now I just have a 4 pin plug on the Y Axis driver and male connectors on the rotory and normal Y axis so I have to manually switch them. 8 months ago. Mine's been working great. It's a pretty simple job actually. You can also import files like .svg, .dxf, .jpeg... For sending the G-codes to the arduino, LaserGRBL is being used. 39 Comments . In my school, we have a cnc miller, so the plates were cut by one of my teachers. Question Now I will explain the basic design of this project. Because a 40 W CO2 laser will be used, the laser itself needs to be cooled. or Best Offer. 2. There are dozens of methods in use around the world, everything from minimal cost low tech home brew solutions to high priced commercial chillers. My DIY CO2 Laser Tube Cooler One important part of keeping your laser working at its best is keeping the tube temperature consistent. It's written in C# with Visual Studio 2017. Again great job and hopefully others will jump on board and build your creation. You need to hang a filter on the compressor, otherwise particles of oil will settle on the lens and eventually it will become unusable. Hello, I would like to know what is that piece and what it does. This is an amazingly thorough instructable. But of course it depends on your goals. on Step 16, My son and I built this guy (or were rather inspired by it). 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. Grand Prize in the Microcontroller Contest 2017, Second Prize in the Design Now: In Motion Contest. This was a really fun project, I worked day and night on designing, building, programming and testing of this lasercutter and I truly loved every second of it! 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. See more ideas about co2 laser, laser cutter projects, laser. How is yours going? See attached photo. I made a scheme of which parts can be cut out of every profile, i added it in this step.
