While I was printing my machine David continued to improve his cutter design. It really is addictive, and having a quick change tool mount makes it so much fun to try different things. The needle cutter has none of these drawbacks. Now that it's working it's a wonderful tool to have for easily and accurately cutting large sheets of foam. Thanks both for all your great work. First v2 attempt failed pretty spectacularly. Twenty minutes or so later you have a sheet of parts that are accurately cut, printed collar in moebeast’s Foam Ripper. What really surprised me is how much the cut quality improved with the vacuum table. Phase III will be a drag knife for cutting vinyl decals. TPU/TPE needled holder for MPCNC needle cutter. So...with all that and my experiences in mind let's review how to build one without going through the months of trial and error I did :D. Then, put them together! load on the needle, i.e. I hope you give it a go and this helps some people avoid the issues I ran into with mine. It should then be easy to add the tach to marlin. There are people experimenting with some 5-6w lasers but it looks like the big 30w+ co2 lasers are the way to go for cutting foam board. bolt on the flywheel. Anyway, that's a side track, sorry! DOWNLOAD Thingiverse. It just takes very gentle pressure to pop them loose - though on the smallest pieces I'll sometimes carefully run a sharp knife over the bottom of the cuts to free the pieces first. A LowRider can easily handle this size, is cheaper to build, and can be The downside is I live in southern AZ where summer temps regularly hit 110F (44C) and higher. For me the two biggest expenses were a few dollars for several pieces of piano wire to make the needle and $13 I spent on a digital optical tach for dialing in the speed correctly. This involves swapping the Dewalt router for a 2.8 watt laser diode for engraving and cutting. The PLA can be made much stronger by annealing it. But they seem to generate more friction and don't dissipate the heat fast enough. This is also similar to how a tattoo machine works and there are a number of different ways to achieve the conversion of rotation motion to a reciprocating up/down movement. Washers must be small enough to not touch the outside (moving) part of the bearing. – All axis can be any length you prefer, anything over 3 1/2′ (1M) would require small mid-span supports to increase rigidity, of course smaller is better. Then I cut an opening in the side to attach a 3d printed plenum that adapts my shop vac to it. Currently the only options are no mount or the hicwic mount. This tension helps keep everything in line, or at least at the same angle, so that the needle isn't jumping around all over the place. It took me close to a month to print the parts with my first test assembly happening on March 13th. DOWNLOAD Thingiverse. Printing it requires support due to the design of the mount. I just move them around to clear the cutter while it works. And I now live in Yuma and VMA-213 (who the old black sheet squadron TV show - that featured corsairs - was based on) are based here. I fired it up...and it scared me...but holding it in my hand I was able to make some not very straight cuts my moving it across a piece of foam board! 46. Dieser Pinnwand folgen 818 Nutzer auf Pinterest. Our current theory is that the higher mass of the welding tip held in more of the heat generated from the friction of the needle while the low mass inflation needle an dissipate the heat much quicker. Support, Chain. The design of the MPCNC means you loose a good bit of working area. Then just had to move my weights around as it cut :D. When the cut is finished the work will usually be slightly stuck to the spoil board as the two foams slightly melt together from the friction generated by the needle. Basically I added options that let me reset the zero position on the machine, turn the needle on and off at a set speed and a few other common commands. Is the tubing you chose galvanized steel? The small laser diodes are a great addition to the MPCNC and are great for cutting balsa, cardboard, paper, posterboard, cork, dark dense craft foam, as well as engraving in wood, anodized aluminum, and painted surfaces. In part, trying to justify purchase of my new Prusa I3 MK2S printer and also to satisfy my rather new-found interest/curiosity with “corexy” technology… here’s a MPCNC-inspired CoreXY-variant laser engraver/cutter I’ve recently built for fun. So I dug in on building a MPCNC. Foam board is also often However - while I was fighting with flying needles David and others continued to experiment and improve the basic cutter design. At 8000-10000 rpm you Everyone uses fairly large motors, although the actual power used is very low, around 10-20W. I had looked into it a few times but always decided it was too expensive to justify. Others have built them from aluminum. More Recipe For Disaster. in the browser based OhShape (note that you can see and use other people’s modifications): It is important that the foam board does not move during the cutting process. It looks like the governor stuff in blheli will do what I want, I just need to find time to play with it. I chose to 3D print my cutter. The motor mounting screws can be changed to match different motors, the height can be adjusted to experiment with longer/shorter needles, and the needle guide mounts can be changed to match what the user has on hand. With a 0.025" needle the kerf is also very small, not quite as small as the needle itself but still far smaller than the kerf from an endmill (and some people have used even thinner needles - though they can be problematic and wear quicker.) Includes safely clips and stores up to a two-year supply of syringe needles. That's what I love about Instructables.com, there are so many things I never even knew existed! Mpcnc site have a nice pdf baout installing a 1W laser on the machine. Start manufacturing today with the 8' x 4' CNC Router Kit 16-20mm Rails and Ball Screws. DOWNLOAD Thingiverse. Thanks for sharing the whole process. 67. Cell voltage * Xs = pack voltage.). 1.5KW 3Axis 6040 CNC USB Router Desktop Engraving Milling Carving Machine 3D Cut. on Step 9. This is a standard example sketch that ships with arduino and basically works the same as a servo tester...just a bit more cumbersome. Quote: With a 0.28" needle the kerf is also very small. I knew my printing time estimates were off from doing smaller prints but didn't realize how much worse the estimates would get as the print times went up! There are tons of builds in the threads I posted on the last step including a few detailed descriptions of how people have built theirs. We've also increased the length of the needle which makes them last longer since they don't "bend" as much in one spot. It will cut with a dull tip, but will tend to drift a little and leave a very ragged bottom of the cut. either start with smaller (M2.5) washers, super-glue them to some scrap wood and drill them out to Contribute to jhitesma/parametric_needle_cutter development by creating an account on GitHub. OpenFlexure. ESC Feedback. Still, my printer was new and that's a LOT of printing to build that machine. Recipe for Disaster. The (3mm inside diameter) bearings can be harvested from broken motors, or a pack of 10 is about $2 I just want to stop and thank everyone who voted for this in the CNC 2016 contest, I'm overwhelmed by the response to this instructable and can't wait to use the new router I won! Love it worth the money and so easy to use . Faster motors need to run at very low throttle, where ESC and servo testers All the assembly instructions (less … It’s On my initial 2'x2' setup this made sense since I moved the machine around quite a bit. Not entirely sure why but it actually made a very big difference. So I didn't dig right in but just watched for awhile. Wind the Z-axis down until you can hear it just touch the surface. Report abuse. Runner Up in the Design Now: 3D Design Contest 2016. They traded in their corsairs a long time ago and were flying harriers (another of my favorite planes...but one I doubt FT will be doing a foam version of anytime soon!) Most tattoo artists use a few rubber bands to pull the needle shaft in towards the tattoo gun. Some would break in half just sitting on my desk! I spent a good bit of time going through the stock at the store to pick the straightest pieces (the clerks will look at you like you're crazy...but I'm used to that with all my projects!) This is such a cool idea. Motors of around The two big limits on speed are the way it's geared and how stiff the machine is. Some people setup their machines to run a break in pattern for a few hours with it going back and forth and up and down and round and round before using it. TimSav machine and moebeast’s Foam Ripper, which are even cheaper and simpler, but harder to use for other things. Apply transfer film to the weeded crown and peel it from its backing paper: First Vinyl Crown – transfer film. Orion Motor Tech 40W CO2 Laser Engraver Cutter with 12 x 8in Work Area, Desktop K40 Laser Engraving Machine with Digital Control, Red Dot Pointer, Detachable Wheels, Compact for DIY Home Office. I already did a few basic ones in my fork of Marlin: https://github.com/jhitesma/Marlin-Folger/tree/mpc... . Cowling Duct. The original design used a 3D printed flywheel which had to be carefully balanced to run smooth. Though I wasn't willing to order more PLA until the weather cooled off - it may survive in my shop but I don't want fresh filament sitting in a hot brown truck in 110F+ weather before I even get to print with it :D. If I can find an affordable local source for 1" stainless I'll probably upgrade to that. 381. This thing had potential! sits on the work surface, with nothing between, and the vacuum pad not only pulls down the foam The birth of this process for me was using my new 40w laser cutter and Fusion 360 slicer (I think it used to be 123d make), and finding the a4 footprint a bit restrictive. And if you're just planning a build there's piles of information and personal experiences you can draw on to base your plans off of. Oh...and also it can be considerably cheaper. Alright - now...let's build a CNC machine to mount this thing on first! Needle Cutter Theory - The theory behind the needle cutter is that it works very much like a sewing machine causing a sharp needle to go up and down rapidly enough to repeatedly puncture the foam board. The MPCNC can be built for a few hundred dollars and as well as cutting DTFB can also be used to machine plastic, wood and some light duty aluminum work. A 3D printing head is also handy since you can do some BIG prints on this if you have a big enough nozzle and/or patience :D I kind of want to add a rotary head next so I can engrave and mill cylindrical objects...and maybe even put an electric kistka on it to do some pysanky eggs for Easter this year like an oversized eggbot ;). The first obvious sign was that the needle was visibly bowing out while cutting, bad enough that it wore a groove into the base of the cutter bracket where the needle guide attached. The needle is guided by the nozzle from a MIG welder, and helped to stay straight by guide bearings. Would some other round or tubular stock make it travel more accurately or faster or are you entirely happy with it as is? Contribute to martindb/mpcnc_posts_processor development by creating an account on GitHub. That said I do like how little contact there is with the work and the quick and dirty vacuum table I made worked great for almost 3 years before I left it sitting crooked and it warped. I used a tool diameter of 0.8mm after measuring my needle, and set the feed rate at 10mm/sec (or 600mm/min) and the tool depth to 8mm matching how much needle sticks out past my guide. There are also shirts, hoodies, and other fun stuff available Here, and Here. poorly balanced and needs to run at lower speed, reduce the feedrate accordingly. 3 years ago, Glad to hear you enjoyed it! My cutter fell apart! vacuum pad solves both problems. Reviewed in the United States on April 2, 2019. My original 2'x2' machine was much better for milling due to how much stiffer it was. 99. But they don't cut dollar tree foam board nearly as well as the needle cutter. That's always fun! Mostly a matter of cutting new longer pieces of conduit and then reassembling it with them. The EMT from Home Depot was much shiner and nicer looking - but I had a much harder time finding straight pieces and it's surface was considerably rougher. I even got brave and tried to cut the RotorRiot logo with fairly good success. I really want to experiment with the governed modes in blheli to see if I can get the motor to run a constant speed without using a tach to dial it in. David shared his designs on thingiverse starting with his first 3D printed cutter using a standard brushed motor: http://www.thingiverse.com/thing:1138627. workpiece but also pulls itself down against the work surface. Updated MPCNC Brushed Motor Foam (Needle) Cutter. Whoops, thanks for catching that! But I also realized just how big this machine was going to be! may have poor resolution, and the RPM may hunt or surge. Result wil be shrunk slightly, which can be used to your advantage if you need a tight fit. Though strength isn't really my concern. My good 12v supply is burned out and I didn't feel like rigging up another computer supply...so I just used a 3s lipo pack which is 12.6v fully charged but nominally 11.4v - close enough for testing. So I went back and scaled by only 170% instead which gave a better fit even though the measurement suggested it would be a bit too tight. Simple clipping action snips off and retains needles within clipper. It's possible to just create a customized firmware for an ESC that would do it but that's a bit beyond my coding skills. Moebeast’s Foam Ripper contains an STL for the manifold vacuum nozzle, or you can build a square funnel shape from foam board. A 2s lipo is only 8.4v fully charged and 7.6v nominal. This mechanically simple approach is easy to build and get working - but does mean the needles are consumable as the repeated flexing does fatigue them over time. Needle holder for MPCNC Needle cutter. The bigger the machine the less stiff it is. A few people have tried running them much faster but it quickly becomes more difficult to maintain due to the forces on the needle and the issues I experienced with the needle flying off the crank. This past summer I ran the AC on low though and it didn't hurt my electric bill that badly. A MPCNC can be built large enough to handle a 510x750mm (20”x30”) sheet of foam board, but it won’t be stiff A good needle-nose tweezer works wonders! But the vac table I made is super cheap and easy to replicate - I just cut 3 sheets of foam board, one with horizontal slots, one with vertical, and a 3rd with holes where the slots line up. This tool does exactly that, much cheaper (and more safely) than a laser. V1 Engineering logo stuff available here in the shop. I found mine worked quite well as it was. 501. $1,055.00. Free shipping. Right now my needle is a little too long so it's kind of sloppy and isn't creating a perfect cut on the bottom surface, but I kind of like this since it holds the pieces in place. Things to watch for are the crank deforming and the needle bowing - both of those are symptoms of running too high of an RPM on the motor. Very cool! Looking at the video again now it's obvious even at regular speed that the crank was deforming from the high RPM's. When I eventually finish the vac table I'll hopefully remember to make a new instructable for it. The pieces will usually still be stuck slightly in place. On the machine I setup for the cut by putting down a piece of 1/2" pink insulation board with carpet tape as a spoil board and then used a few bits of regular tape to hold my foamboard on top. Enlarging the MPCNC was fairly straight forward. We've pretty much abandoned the crankshaft used here and switched to flywheels which give much smoother and more reliable performance. I haven't fully debugged that yet but I think what happened is one of my motor wires rubbed against the motor bell and cut through the insulation shorting it out. I haven't tried this yet but as long as you don't add too much oil I can't see any harm to trying it. plastic mount, and the bending load on the needle can break it at the top. One of the first needle cutters that inspired the person who inspired me to build mine actually used a plastic spoon as a foot like that. I had just build my first 3D printer less than a week before, and had seen the MPCNC on thingiverse but the idea of a 3D printed CNC machine just sounded like a bad idea to me so I skipped over it. Baking. 8 x 4 Ft. CNC Router Kit Rail Guide System 16-20mm Rails and Ball Screws Enjoy having a complete kit with less work. I also decided to first build the machine on a 2'x2' footprint (giving about 13"x13" work area) to test and debug before rebuilding it a third time to it's full size. It could probably be done with annealed parts...but due to the shrinkage I'm not sure it would be worth the effort. I was going to have to clean out my old home office and finally convert it into a shop - lots of work...but well worth it! in about 20 minutes. Next I powered up the cutter and used my laser tach to dial in the speed to ~6,000RPM, Finally I selected my file and hit go. I opened the SVG in inkscape and selected all the objects then scaled by 180%. Which led to a number of weeks of frustration and continued revisions trying to figure out why I was having problems with my needles flying off. The needle is formed from a length of 0.5mm (0.025”) music-wire and attached to a small ball-bearing I was able to glue the cutter back together and keep going. Instead of a vacuum bed how about using a lightly sprung shoe similar to a sewing machine. Aviation. It may be easier and faster to cut the first two with a craft knife, and use the machine to make the grid of holes in the third sheet. At the proper speed it's a lot less scary sounding and I've yet to have a single needle go flying since taming it down. The biggest problem I had was due my own sloppiness in creating the gcode as I had to trace a bitmap to get the vector art to pass to my CAM software and rushed the job out of excitement leaving a few minor errors. I know there was at least one person who was working on putting a plasma cutter on an MPCNC like this but he was having issues with the arc causing interference with the RAMPS board and/or stepper drivers. This kind of breaks the timeline a bit, but once I had the smaller version up and working I dug right in on getting a needle cutter working. Home. Next let's go over some tips to help you avoid my mistakes if you decide to build your own. I already started on this but it's been on hold mostly because I want to finish a vacuum shoe for my spindle first due to the mess it makes cutting pink insulation foam. I got my original EMT from Lowes and it was very dull - but very smooth. First a little more background: Needle Cutter Theory - The theory behind the needle cutter is that it works very much like a sewing machine causing a sharp needle to go up and down rapidly enough to repeatedly puncture the foam board. feedrate (mm/min) of ONE-TENTH the cutter speed. MPCNC foam-cutter attachment by dkj4linux - Thingiverse Download files and build them with your 3D printer, laser cutter, or CNC. DOWNLOAD Thingiverse. A vacuum table! I used MakerGeeks PLA for these parts and I've had ongoing issues with their PLA not always feeding well and suddenly jamming up like the nozzle was clogged even when it isn't. It has been virtually assembled and is now a one-piece print. The problem is I forgot that ESC's aren't very linear, and I missed that David had suggested using a 2s pack instead of 3s...I also made a few silly arithmetic errors. It's important to pay attention to which way the motor/crank turns and which way your coil sits so that it can't get caught on the crank as it turns. This will aid in formation of nucleation which makes the PLA part much stronger. My plan of building on the dining room table wasn't going to work. David went back to his original air inflation needle and I followed. I also cut a new FT Scout to replace my worn out one which took a little over 30 minutes. So...I chose to reprint all the parts in PETG. Again, fantastic instructable. It's fairly straight forward. Here are DXF plans for the 3 sheet pad - although you need a working needle cutter to use them. But as I mentioned David had made some improvements to the basic cutter design. The foam cutter uses the simplest approach by taking advantage of the flexibility of the needle. I really need to do an updated 'ible though as the design has really evolved a lot since I wrote this. The new parts make for a stiffer machine but I haven't had time to reprint mine and upgrade yet. So my initial needle broke fairly quickly. However it creates a lot of dust which is a real pain to deal with due to the static charge it picks up. It was your instructable I was reading on the train this morning. Pins and tape can There was also some bowing to the foam board which made the problem worse and just taping the board down wasn't sufficient to eliminate that. Ideally you want a needle speed matched to your feedrate to … And finally I decided I had to give it a try. I did run into a few issues due to my choice to use CAT5 network connectors on the stepper wiring to make it easier to connect/disconnect. The white foam reflects too much of the lasers energy. But every time I'd finish printing the filament would snap just above my extruder and the next 6-10 inches would be brittle. rolled aside when not in use to leave most of your bench for other work. Needle Cutter Re-mix 15,000 RPM. Some parts were difficult to assemble already (and I've got my printer dialed in very well, I get outstanding single wall prints, and can do the negative tolerance test from MAKE magazine and get all of the pins out without tools - though the last one does require pressing hard enough to leave a mark on my finger!). Then, the world got turned upside down and the final touches actually got put on hold for a bit. Building the MPCNC really deserves it's own instructable, one of these days maybe I'll find time to make that happen. enough to mill aluminum. With the cutter finished mechanically it was time to wire it up and test it out! It fit but was just a little loose. I did make a non parameterized version with the default mount: http://www.thingiverse.com/thing:1976501 but it's not wonderful. Did you make this project? The shop-vac noise can be reduced with an inexpensive router speed control to reduce the speed. Stick it on something desperately in need of decoration and peel off the transfer film: MPCNC Vinyl Cutting – crown on mug I'd actually wanted a CNC machine for much longer, well before I got hooked on RC planes. The suggested setup for the cutter was a 12v power supply or 2s Lipo, a servo tester to control the ESC (Electronic Speed Controller) and an optical tachometer to set the speed. Share it with us! I cut mine a little long initially, then wrap them around an old drill bit to create the coil that goes over the crank. Since the time I wrote this a couple of people have tried that and had good success with it. That turned out to be a bad call. The components here aren't critical. Cutting the T-rex took 28 minutes. There are various versions of the machine design for different sizes of tube since apparently different parts of the world have standardized on different sizes. Having seen several mentions of foam cutting machines/methods in this forum, this might be of interest to some of you... especially RC folks. A lot of those of us working on/with these looked at tattoo gun designs for ideas - but they use a LOT less movement of the needle so a lot of things that work for them don't work for us. What I saw continued to impress me. ;). This was likely due to a combination of the needle being too long and being run way too fast. The "floating" tip holder uses a short section of carbon arrow shaft for a spacer/insulator and a 3-point set-screw arrangement to effectively isolate the hot (in use) copper tip from the yellow PLA plastic.
