To secure the ends of the chains, I used 3mm hex wrenches which fit quite nicely in the #25 chain. 18 days ago. After I cut the door to size I decided I wanted to increase the X travel to a full 30" which required widening the table. Question This compact plasma cutter weights 17.6 lbs. It will droop and no matter how tight you tension it, it will still droop to some degree. This is so no dust gets sucked into anyplace it shouldn't be. Noticed that articulated cable support going to the router carriage? Best Plasma Cutter Comparison Table. These are usually made from milled aluminum but I figured some plywood and some aluminum tape and strips would work. Question Installing a bumper yourself can help you save on labor costs, but the price of the bumper can still be hefty, especially if your car is a rare or luxury model. Instead of building from scratch I re-purposed an Ikea cabinet I had available. Notice how far apart the the pairs of Y axis v-bearings are apart on the bottom of the gantry side plate? The one bearing is attached to the movable arm that allows for a quick and easy removal of the dust shoe from the machine. Loosening this up allows me to precisely adjust the gantry perpendicular to the Y axis travel. The 1/4" shafts of the stepper motors are more than strong enough to keep the motors in place. This setup has proven very good at sucking the dust and chips up. severance thickness, making it an ideal choice for cost-conscious DIY hobbyists. Phidgets.com. Nice effort trying to promote yourself, "acourtjester" / "Big Irish" / "Tom".As of now - 26 Nov 2020 - you have gotten these results on Youtube:Your video uploaded 2 Jan 2019 - 3 likes.Your video uploaded 14 Nov 2018 - 5 likes.Your video uploaded 29 Mars 2018 - 7 likes.You say: "I have sold over 500 sets world wide".The numbers speak against that claim. 4 months ago Maybe I'm an uber machine designer and fabricator. This opened up area for the dust collection system to the right of the router. Make it as rigid as possible (for a plywood design). Reply Who knows? Why a solid core door for the machine base? Mechanically, it would have been easier to go with two steppers for the Y axis but I only had one motor available at the time and I had the shafting and bearings to fabricate the drive. Best For the Money: Editor’s Choice: Image: Machine: YesWelder CUT-55DS: Hypertherm Powermax45 XP Hand System w/o… Plasma Cutter, Spectrum 625, 90PSI,… Hobart 500566 Airforce 40i Plasma Cutter: PrimeWeld 50A Air Inverter Plasma… Forney Easy … Puzzle - Lock - $15. I have a small basement shop and I wanted good dust collection on this machine. metal with 3/5 in. All I know is I'm very happy with it. for years. The router has been rebuilt with a new setup where I moved the z-axis mechanics to a new router carriage. The door will be the actual base for the router. Besides, it looks cool when the entire gantry moves up and down. This allows the router carriage to slide past the side supports (more on the right than on the left btw). It was a tough but exciting project because I didn’t really know what I was going to do with the electronics at first. I've been hesitant because I don't really have a plans set ready to go and many of the metal parts have been machined which would be difficult to replicate for someone without access to a metal lathe. This is a hobby CNC router I built for myself that I'd thought I'd share with the Instructables community. Answer That sounds to good to be true with a DIY roller chain driven plywood router but that's what I've seen in some of my testing. I've been experimenting with materials, cut depths, and feed rates to see what the router can do. Works quite well. Total cost was about $600 because I purchased new stereo equipment to replace the old stuff. Great work I have built 9 table for both routing and plasma cutting, I use similar setups for the drive assemblies but in different configuration. For X and Y axis motion, the carriage has one NEMA 23 240oz (torque) stepper mounted. Why mount the Y rails under the table? Maybe the stars were in alignment? First, my thinking is that if I moved the Z axis mechanics out to the ends placing them between the gantry and the gantry side plates, I could spread the loads out and increase rigidity. I love this machine and I have started ordering parts to build a 4X8 CNC router with my father, it will be using your roller chain ideas. A tensioning screw runs though a t-nut which bends the ply tensionor out and pulling the chain taught. ↳ DIY Plasma Table & Accessory Discussion Forum; CAD-CAM & CONTROL SOFTWARE FORUMS ↳ General Discussion ↳ Autodesk AutoCAD & Fusion 360 ↳ Get AutoDesk Fusion 360 FREE ↳ BobCAD ↳ C&CNC CommandCNC ↳ Corel Draw Graphics Suite ↳ CorelDRAW Free 30 day trial ↳ FlashCut CNC ↳ Inkscape ↳ Download Inkscape for Windows Then have some string wrapped around a door labelled. Yep, I used 25P roller chain in this build. This means the dimensions of the machine will be relatively stable during a cut. UPDATE: I've dumped the flying gantry design of this router. I'm using these currently. Things to consider when selecting your cutting machine. I avoided all that complexity by hard mounting the motors to the screw shafts. Before I started this build I'd studied other chain driven designs and always noticed one thing. Flying gantry? And third, their heavy as hell and I thought all that mass would be advantageous in soaking up vibrations from the router. There are no plans for this router. Anyway, wow! Part is the cost of transportation to and from a reputable company. I did this to mount the gantry plates as rigidly as possibly. That's why I posted this build. The dust shoe was machined (first thing I cut on this router) out of two pieces of 1/2" plywood. Able to use the router as a bench top when not routing. If this were a production machine that was homing to the same spot for every cut, machine stability would be a bigger factor. One wrinkle with this design is that since the router carriage moves up and down with the gantry, I had to come up with a design that keeps the dust shoe on the work piece. What is cheap is 1" angle iron at my local home center. It works in 3D printers and as it turns out, is working quite well with this router. The Lotos LT3500 Plasma Cutter is designed The Lotos LT3500 Plasma Cutter is designed for light-cutting projects. This made the plates longer which required more table length to get me the 60" of Y travel that I wanted. Like a drag knife for sign vinyl cutting, diamond scribe holder for metal etching. Certiflat 24"X48" Heavy Duty Welding Table. You don't see this much on DIY routers for some reason. The dust cyclone is mounted on top of a standard 5 gallon bucket and keeps most (if not all) the dust out of the 8 gallon shopvac that I'm using. On the back of the machine inside the black box in the center is an Arduino Uno which is running the Estlcam controller software. The router has turned out to be precise and it has a nice speed adjustment built into it. Besides adding a ton or torque, they definitely helped in the precision category (more on that later). My interests are varied and span the gamut from wood and metal fabrication to CNC machine design and bui…. These other chain designs always seemed to have the chain hanging out in mid-air, unsupported, with some sort of flimsy looking tensioning system on the ends. A 5x10 table can be constructed in 40 hours which saves DIY builders thousands of dollars + shipping costs compared The motors are kept from spinning by the wood bracket with that rubber bushing on the end (which allows the motor to wobble if it has to). Don't worry, your crew will roll with it and have a blast. The Makita router is mounted on the left side of the carriage. These figures are approximate representations, and the actual power consumption of your appliances may vary substantially from these figures. Clearly.When you click "About" regarding your account on Youtube it is - blank.Maybe you are sincere - but IF you want to at least SEEM like it - you should improve on a lot of things.The first thing should probably be - NOT trying to promote yourself in a comment regarding what another person has created and publishes as an Instructable of 'how-to-do'. Arguments against are that it stretches, it's not very accurate, and it caused the fall of the Roman Empire! The control system is Arduino UNO based and I'm running the EstlCAM CNC software (which is awesome IMO). The gantry is built from two layers of 3/4" ply glued together. Look for the new design and build Instructable within the next few months. Question . 4 months ago. .". Did you make this project? It did! I first built this with the stepper's driving the chains directly. ;)". Mainly that it was very slow. Precision Plasma LLC has been in business since 2008, Precision Plasma LLC specializes in the mechanical design of CNC plasma cutting, Start to Finish Video Building a Magnum HD Table. Beyond a couple of initial sketches to determine general size, lengths, and spacing, this router pretty much grew out organically as I was building it. As to the design I came up with. I use these doors as bench tops in my shop. Notice the gantry overhangs? What that droop on a linear motion system means is that you will not get consistent movement along it's length. In the electrical box is a 10A SSR (solid state relay) which switches the router on and off. Seemed to work well so I cut the 45 degree plywood rail beds on the tablesaw and mounted the angles to the underside of the router base. Secondly, removing all the Z axis mechanics and motor from the router carriage, greatly simplified wiring going to the carriage. $ 305.99 $ 305.99 - Add to Cart (1 ITEM) Details; Shipping; FAQs; Details. The router is the Makita RT0701C 1/4" trim router (earlier pics show a cheap Harbor Freight router which has since been chucked). Something you may have noticed are the plywood strips attached to the edge of the door/router table. The router carriage is glued up from two layers of 1/2" cabinet grade plywood, much the same way as the gantry side plates. Plasma Cutters. The entire gantry moves up and down for the Z axis motions. on Step 8. Not well pictured, but tensioning of the v-bearings onto the angle is accomplished by a bolt and dowel-nut setup. 2 months ago. On the dust collection, I'm playing around with different configurations. Question To connect the two would be a flexible coupling. On the plans set, I'm slowly working on it. Linear rails for CNC seem to be a dime a dozen nowadays on eBay and Alibaba, but in 6' lengths? Third, I figured why not? It could also occasionally go out of alignment if one side skipped steps. Do create a plans package I have sold over 500 sets world wide, it will give you extra cash for other related projects. This was accomplished by mounting the dust shoe on an arm that allows it to freely move up and down in relation to the gantry. I also kept an eye on mounting orientation. 8 weeks ago. This powerful unit is forceful enough to cut 2/5 in. The screws would be mounted in a bearing assembly. No whirlygigs! Combine the two, and we get the linear rail system I'm using in this build. It also allows me to use the router as a work/assembly bench when I'm not routing. The cabinet was completely disassembled and then put back together using adhesive at every junction. There's been issues of course and It's a continuing learning curve. Yeah, I know. And finally, there is a mechanism that raises and lowers the entire gantry that moves the router up and down (Z axis). My first project along these lines was a touchplate for automatic zeroing. About: I'm a long time woodworker, R/C hobbyist, amateur engineer, and patented inventor. What an accomplishment you've made. The bottom pad was cut out of a painting pad and allows the shoe to float over any screws or bumps in the work piece. . The X axis chain sits in the bottom of the top angle of the gantry. The carriage has four of the v-bearings that run on the top and bottom angles on the gantry. 4 months ago. There's no drooping in these chains! 8 weeks ago. In a typical setup, these motors would be hard mounted to a base. Also for the second one, that you present here.It looks very good, and congratulation on realizing it. . To accomplish this, the gantry has a length of 1" angle iron in the vertical orientation that sit in v-bearings attached to the gantry side plates. Great work I have built 9 table for both routing and plasma cutting, I use similar setups for the drive assemblies but in different configuration. Very nice project, but have you considered the expansion of the wood caused by humidity variations? Maybe that reduction on the motors had something to do with it? I reinforced the cabinet by melding in a 2x6 substructure on the bottom. Dust collection. The Y axis chains lay in a cutout in the Y angle supports. But I need to know where you got those #25 idle sprockets. Grand Prize in the First Time Author Contest. Solid chain, you'll need something to cut me with. Many launch providers think reusability is the best way to lower the cost and delay involved in getting to space. What will happen if 5' of it suspended horizontally in mid air? Casters and levelers where added for mobility. Not many pics on this one I'm sorry to say. If your attic is accessible and you like home improvement projects, you can Do-It-Yourself with help from our DIY Guide to Sealing and Insulating with ENERGY STAR (PDF, 12.7 MB), which offers step-by-step instructions for sealing common air leaks and adding insulation to the attic. As to motion, I'm using stepper motors and roller chain. Since I zero the router to the workpiece at the beginning of each cut, I figure dimensional variations due to humidity do not factor in. To provide the Z axis motion the entire gantry moves up and down. I agree with Estlcam I have used it for doing plaques and other projects. At any given time the machine is in a certain state depending on temperature and humidity. Chain two sliding doors together. PBC Linear IVTAAQR aluminum extrusion with, Build a complete 5x10 table for $7,000 - $7500 (steel prices vary), 1. 2 months ago. I'm moving the entire gantry for a few reasons. On the wall is a little Windows 10 media PC that is running the Windows side of the EstlCAM system. This is not a detailed build log of the router but more of an exploration of my design choices that went into this somewhat unique tool. Roller chain has some weight to it, even #25 chain. What may not be obvious is how I have the two Z motors attached and mounted to the jack screws. A couple pieces of plywood and some hinges, and a quick and easy cabling solution to the carriage is the result. Yes, I said the entire gantry moves up and down. Precision Plasma LLC supplies mechanical gantry kits to allow DIY fabricators the ability to fabricate a high quality CNC plasma and routing table without the need to engineer or source the mechanical components. Good for any size chain. Hope you enjoyed this write up. Sorry to say but this is about it for historical photos of this build. Every tool needs a good base. You can check that out at part two of this build series. By classic I mean it has a gantry that moves along the length of the machine base (Y axis). The Arduino case has holes drilled into the top and bottom for the same reason. 2021 best CNC plasma cutters, affordable CNC plasma tables for sale at cost price, with plasma table sizes of 4x4, 4x8, 5x10, 6x12, 24/7 free plasma cutting service, custom 2D/3D plasma cutting plans, solutions and ideas from 2021 best plasma cutter manufacturer - STYLECNC. For your original prototype, how much it cost? Three plastic v-bearings were used as shown in the pic. All parts are cut from 3mm / 1/8" Mild Steel Plate.ALL THE SOLIDWORKS, STEP & IGS FILES ARE ON GRABCAD… What I did with this design is that the chains are supported along their entire lengths. I'm not saying .005" accuracy will come out of this machine with every cut but at even four times worse, it's a lot more accuracy than I was ever expecting. Purchase a Magnum 7 gantry kit from Precision Plasma LLC. What's that coupling looking thing in the first pic? How's .005" repeat-ability sound? Plasma Tables; fabBrake; Welding Positioner; Clamps & Accessories ; Home / Products / Certiflat 24"X48" Heavy Duty Welding Table. UPDATE: I've been getting many requests to publish plans for this build. This may seem an odd way of doing this but this method eliminates the flexible coupling and fiddling with alignment. EXAMPLE OF CUSTOM TABLE BUILT WITH THE MAGNUM GANTRY KIT, Marshall Maas of M-FAB customized his table build by adding additional features. Since I have that overhanging gantry, I was able to make the router carriage longer (spreading the v-bearings further apart) which increases rigidity in the X axis. Comparison table. In the initial testing, I was getting a lot of skipping in the (weak) motors I was using at the time. Share it with us! The up and down power is supplied by a NEMA 23 stepper and screw assembly on each end. This setup allows the router to cut from edge to edge a full 30" in the X axis. That's 0.127mm for you metric types. Answer Wow!And Thank you - I have been thinking of a way to build a stock flattening table for cheap (since I'll seldom use it!) Plasma cutter Reviews. You have every right to be proud of your work.Maybe it's the frustrated editor in me, but I believe it should be "too good to be true" and "not too shabby." That's a compression coupling that joins the left and right Y axis sprocket drives. Do create a plans package I have sold over 500 sets world wide, it will give you extra cash for other related projects. Not so cheap. To me the spindle bearings are not outside the realm of DIY service and or minimal cost service. Tensioning is handled by flexible sections of ply on one end of each of the chains. This left the top clear so the entire surface could be used for cutting. What size stepper motors did you use?Could you add a link? Use as much stuff that I had laying around the shop as possible. The primary construction material is plywood. The only thing holding those motors in place are the 1/4" shafts stuck into the 1/4" holes I drilled into the screw shaft ends on my mini-lathe. Thank you for your answer. After a cut, there's hardly any dust left on the work piece or floating around the shop. And the Grooved Bearings (V and U, too) were another item I hadn't thought of.PS Love your fully supported roller chain two! For the initial build, I figure I have about $900USD into it not including the PC and Ikea cabinet. To the left on a shock mounted base are the TB6600 stepper drivers. Finally, I used a commercial solid core door for a bench top. You should had mention this part in the title as well. Give the RAR file + BOM to your favorite laser cutting company to quote then .cut / fold. I agree with Estlcam I have used it for doing plaques and other projects. I had the sprockets and bearings available so I added the reductions. The Z axis is currently set to 20IPM. For one, I had it available. Anyhow, I didn't know all that when I started this build and I had a bunch of the chain left over from another project. It's getting more elegant with each rebuild! Moving the entire gantry up and down for the z-axis motion worked ok but it had issues. I didn't use timing belts, ballscrews, or rack and pinion. I'm enough of an engineer to know that roller chain could have issues but I had some ideas on how to mitigate those. It certainly can be done, frankly its on my bucket list of learning, but not cost effective. CNC Plasma Table: PLEASE NOTE: I do NOT supply kits for these. Z motor mounting. This is a classic XYZ 3-axis wood cutting router. Currently, for cutting plywood and MDF, I've been running around 70IPM (inch per minute) speeds on a .25 bit with a .28 cut depth. Cost, Time, and Skills: This project took me a couple of weeks of evenings after work and weekends. My day job is in IT. This setup uses the angles in compression to add to the rigidity of the chain mounting. Not to shabby for a machine that might have $900 of material in it. There's nothing significant about these. A wireless keyboard, mouse, and a game-pad finish the controls out. 03-03-2021, 12:37 AM #3. bigwave. What I've decided to do is to develop a MK2 version of my router that I will publish the plans for. I also said to him do create a plans set to offer to make them available for other to enjoy building their own table. Along the top and bottom, 45 degree recesses were cut and 3/4" angle irons where bonded into them using Gorilla glue. Temp and humidity will not change much during a cut. I would add an overhead boom for the Vac hose and router power.https://youtu.be/-C48ROJ-5KQhttps://youtu.be/0oiemc9ZUfghttps://www.youtube.com/watch?v=gn1Xh9PaInc&feature=youtu.beHave funTom. On most CNC routers the gantry is fixed and the Z axis motion is all done at the router carriage. There is a carriage that the router is mounted to that runs back and forth on the gantry (X axis). The wiring to the motors is running through the flexible black cable protectors picked up at a computer store. Secondly, commercial solid core doors are built to be as flat and true as possible. Check the power tags, or better yet, measure the amperage draw with a clamp-on ammeter or home energy monitor like a Kill-A-Watt meter. For the linear rails, I'm using steel v-bearings running over steel angle iron. Hopefully other CNC enthusiasts may see an idea or two that might help them with their projects. To hopefully give others ideas for their projects. Tensioning is done the same way as on the gantry side plates. https://www.amazon.com/STEPPERONLINE-Stepper-269oz... https://www.amazon.com/STEPPERONLINE-Current-Stepp... https://www.automationtechnologiesinc.com/products... https://www.phidgets.com/?tier=3&catid=43&pcid=36&... https://www.youtube.com/watch?v=gn1Xh9PaInc&feature=youtu.be. You can add optional attachments to expand your table use. I'll need to take a closer look at your drag knife if/when I decide to get into vinyl cutting. Exellent! One nice thing with this setup is that the gantry will never go out of alignment due to a motor skipping. The motor cabling is four conductor trailer wire. Pictured here are my first tests using angle iron and the v-bearings. Those slits between the v-bearings allow for enough movement for the tensioning. If you don't know, roller chain has a bad rap in the DIY CNC community. I am having a heck of time finding them. and your angle iron rails introduced me to a way to recycle some steel I've had in my collection (free rails!) on Step 8. We'll be getting into that later. 4 months ago The Y axis motion is powered by a single 425oz stepper that is driving a shaft that is attached to both ends of the gantry. A chain reduction on the axis drives? Are they roll up door hardware? Precision Plasma LLC supplies mechanical gantry kits to allow DIY fabricators the, MAGNUM 7 HD model gantry kit only. The power supply is a 24V 15A fanless design. The pics that follow were all taken after the router was pretty much complete and operational. Something else that's cheap (at least cheaper than they used to be) are 3/8" ID steel v-bearings. To Top. Not shown, but the door was shimmed so it would lay as flat and true as I could make it. First thing you learn when you get your CNC router up and running, is that you immediately want to start improving it. I understand is impossible to be specific, but in big lines, an approximation. Free travel speed is set to 140IPM with no issues. if I was self promoting I would have given a means to contact me, my sales were on eBay and other websites. Grinding and scraping the ways is not. I'll take what I've learned with this machine and incorporate off the shelf hardware as much as possible. The gantry beam is mounted in front of and extends past the side support plates. Cost for DIY replacement: About $300 to $1,500. sounds to good to be true with a DIY roller chain . I'm just a garage DIY guy, but I am incredibly impressed. The stepper drivers are mounted so heated air will naturally flow upward. I'll add content as I think of it and I look forward to any comments or suggestions. I made an effort to use fanless passively cooled equipment for all my electronics. I have stopped offering the plans about a year ago.Your info is the one that is incorrect, my post here was to encourage the poster and others who read his post by showing other things that can be done with a CNC table. Answer Note that the chain mounting and tensionors sit right on the angle iron ends. So why so accurate?
