Just thought I would post an update to this build as well as post some images of the plasma. For the OC I plan on using a gold mirror with a hole drilled in it and a ZnSe window, just a flat plain old window. I don't have the physics knowledge to attempt this one... but I know enough to appreciate the intricacy of what is going on. Keep It Simple, Stupid! Sputtering will happen. As with any trade, creating beautiful and profitable work on the laser … Over-voltage repairThe plitron transformer produced too much voltage. I would have liked to have all inputs and outputs of electronic/electric connections going into a board handling TTL signals, relays, and connections for external limit switches, and then put the logic of the overall system together with microcontroller software. Frankly I thought it was fun. I really like your project and build something similar myself right now. After some tinkering to check all the seals, this was the result and what I wanted to see ^^. based on your interests. Your D-I-Y surgical endeavours can be prevented by adding two safety buttons, either side of the work space, with protective rings, to prevent cheating the switches, so at least you know where the fingers are! But you still need to wear protective eye-wear (glasses) for the times your enclosure has the door open and or you are doing maintenance.b) protect your lungs and respiratory tracts.Another important aspect is the fume exhaust system that depends on the materials that you know you can safely cut. For the Electrical, I am going to simply use aligator clips (well insulated of course) and clamp onto the mirror mounts or the T fitting. With one software that is both a graphics design software and laser … The plasma inside was a shade of pink, which was so bright I had issues taking an image to post here. Dont use pre-stripped wire wrap tools because they only allow you to make two connections. there's steppers and pulleys and belts and drivers and premade systems galore, just gotta make a little investment. You are correct. There are some optics that are specifically designed for the laser itself which would allow you to just take the optics out of the box, connect to the system, and you are ready to go. what i need to make laser for cutting op to 2mm stanley steel ??? In the new system the point of contact to the part is relatively small, when the laser passes over where the supporting table there's no splashing. I followed all post op instructions. its incredibly instructive to see how a system works. Increasing the amount of CO2 in the growing environment produces larger plants. In order to attach the cut quality enhancer to the G-100 two adaptors were machined out of aluminum. First set up a system to mark circles or edges of your beam path with cross hairs in the center of scotch tape.The place your targets on the beam path. I purchased plitron transformer 117042201, with two 55v secondaries @ 9A each, $139.73. I didn’t think to take pictures of it as I went along until I was done assembling it. It was constructed with 12 power hack saw blades. After a while, and some major thinking… there was a problem… How to hold on the optics while the vacuum formed inside the tube. Ablative lasers, such as a CO2 laser, work by traumatizing the skin. on Introduction. The laser has a cnc table that moves parts around a stationary beam source.A table of this size required building fairly large power supply to drive the table's servos. It suggests to me theres still hope for the glass tube guys.What else do I need to cut?You must have a functioning cutting head, that delivers oxygen that flows through the nozzle. The forumula for depth of field isDOF = 2.5 x wavelength x ( focal_length / beam_diameter )2for the G100 laser it calculates to:DOF = 0.027 * (focal_length / beam_diameter)2The optics for the laserThe beam delivery system is composed of a bend mirror, a processing head, a cut quality enhancer and circular polarizer, and a beam expander. The template should be an exactfit when placed over the top of the washer stack. The excess solder on that one side is from the old retention bolt, I didnt bother to remove it. Look forward to updates. I am planning some serious upgrades to the unit I purchased and some fun projects. pls some one send me this project pictures. Question Then epoxy around the glass and the end of the PVC cooling jacket to seal that. With the drill, I made two holes in the endcaps of the pipe. I needed a mirror mount. Laser reflection during operation is also harmful.The most common measure of protection is the confinement of the device/machine to an housing/enclosure. I drilled out the epoxy core on the drill press in about ten minutes. I carefully checked for shorts between any of the exposed wires. The burns are not a result of reflection as shown here, at least they dont occur like this repeatedly. I'd there any benefit to going wider, or is longer more effective? Share it with us! The amplifier produces 3000 watts of RF power. Besides, how would you wield a 250 Watt Laser with 2500 Watt water coolant? so then all you have to do is deal with the forward-reverse inertia problem. Is there a YouTube video? See more ideas about co2 laser, laser… Radio shack part number 276-1570 is a cheap wire wrap tool that absolutely should not be used do wire wrap with slit-n-wrap wire, however; it is a great device for unwrapping. The heat shrinkable wrapping around the windings completely prevented the epoxy from entering any windings. Both parts came from Laser Mechanisms. Then I will use a convex ZnSe Lens that I have and make my own variable focus :D. The next step was soldering it to the adjustment, I removed the old screws that I had soldered onto the mirror mount. The Window I put in it used a tube from an old aquarium vacuum that I had recently replaced, it was a larger 2″ one that fit perfectly inside the PVC. I used a 1/2inch pipe flange, inserted a nipple, soldered, and machined flat. The blades came from ebay and cost about $100 total. The next step was to solder some nuts over two of the washers over the holes you drilled. Perhaps the biggest technical hurdle was that I put my laser support system together using a welder which some people may not have.The optics were pretty much bolt-together parts and I dont think there would have been much time to save there. If I was in your shoes one place I'd do some research is to find out what power density is required to cut metal. Have you tested it out yet? Another way to say it is, most OEM solutions are incredibly expensive.Most of the mechanical parts of the system like the physical CNC table, the chiller, the frame supporting the laser were very easy. This is where I had to solder on the small bolts as shown in the final product. The first image is what happens when you have a leak, the tube glows a very bright purple and the plasma fills the chamber. You also need a cnc table running the part around underneath the nozzle.How much did it cost?Its rude question but...total estimated cost is about $15k or so. Its nice to have a system that can help build itself.The main picture is the table made of the blades. Some shots of the plasma. Get an audible continuity checker. The glass tubing is in it and I tossed on two gromets, one on each end to keep it in place and safe from being broken while I constructed the rest of it. The cutting head was manufactured by Haas LTI.The principal of the cutting head is that the beam enters the top of the head and is directed to a focusing lens that is found in the center of the cutting head cavity. A laser cutting machine is a big investment, and we hope this brief guide helps make … What would you have done differently? Hurts like heck but it cuts while it cauterizes, so there's no bleeding. 5 years ago On the other hand, if you want to save some time it would be best to find an alternative to making the electronics your self.House wiring. I sanded each surface to rough it up a bit, applied flux, then heated each with a toch and soldered. A tank of oxygen is $55 and can easily be used up in a weekend. When I got home, I cut off the last barb on the sharkbite fitting, the washer I selected had a slightly to small center hole, so using a rat tail file I filed this out carefully to create a VERY snug fit… it was so snug a rubber mallet had to be used to get it into the fitting. You bounce the beam from the laser around a set of … That'll leave a mark.No. This really gives me hope! Regarding mirrors, I've had GREAT success using a metric hole saw and used hard-drive platters to cut replacement mirrors for my 60W Epilog Helix. There is a lot of magic (and science!) :). This documentationdocumentation describing power supply formulary says that two servos requiring 10A should never exceed 2 * 10 * 67%, or 13.4A.The manufacture Plitron sells toroidal transformers. The grey clamps holding it are from the electrical department, for electrical conduit. My system is based the Coherent G-100, an RF excited sealed industrial C02 pulsed laser. Keeping in mind that simply buying a laser tube these days is actually pretty cheap (ebay as of the time of this writing has them for about 300 dollars). If the beam is not exactly on center, it gets reflected off the side when it comes out of the nozzle and forms a characteristic pattern that looks like this.Another alignment method I used to cure this problem was to remove the nozzle, and shine a short pulse on thermally sensitive paper. The table was constructed by running two foot long, 1/4 inch threaded rod through the holes at the end of the blades. See plitron's toroidal ratings.At this amperage and using the formula ((80000 * I) / V) I estimate I would need around ((80000 * 18) / 68) = 21167 uF filter capacitor. I would use microcontrollers. The next step was to run the lines and mount the tubing as well as install the connectors for attatching the vacuum pump and gas system. Aluminum tubes were cut 1 3/4 inch for spacers.I tried putting neodymium ring magnetsneodymium ring magnets attached with small bolts in on each bar.The neodymium rings came from ebay. on Introduction, 5 years ago The output coupler. on Introduction.
