Needle Cutter Re-mix 15,000 RPM. DOWNLOAD Thingiverse. Vacuum Table and Needle Cutter (WiP) 3D Printing. So...I chose to reprint all the parts in PETG. The bigger the machine the less stiff it is. Parametric openscad needle cutter mount. The version in my photos is the old version which is no longer posted. Next let's go over some tips to help you avoid my mistakes if you decide to build your own. As soon as I tried the optical tach the problem was obvious. Very cool! 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. 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. 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. The kit comes with enough belt for up to 48″ of total outer X and Y axis dimensions (eg 24″x24″, 36″x12″ or any other combination). Question MPCNC's for needle-cutting will be considered "big" by MPCNC standards... but is "workable" as long as you stick with light loads like needle-cutter, laser, etc. You also wind up with a rather large kerf (the material removed by the tooling) and the detail you can achieve is limited by the size of the tool you use - larger tools give less detail while smaller tools are easier to break and work slower. My initial attempt mostly came out, but I had a belt slip on my X axis throwing off the cuts a bit. 2060 - 2060 Extrusion Bracket. 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. The needle itself is fashioned from 0.025" piano wire I got at a local hobby store. What I saw continued to impress me. So I dug in on building a MPCNC. This can easily be a milling machine, 3D router, 3D printer, laser cutter, vinyl cutter, CNC plasma cutter, you name it. And having a laser and a needle cutter means I can use the cutter to get clean cuts then use the laser to add designs or other markings for the best of both worlds. The (3mm inside diameter) bearings can be harvested from broken motors, or a pack of 10 is about $2 I just finished a laser head with a 2.8w 445nm laser as well and have been have a blast with it the past few weeks (one of the reasons I haven't finished my vac table yet!) when I moved here...and I think they may be in line to step up to the new F-35's soon which at least one squadron has already switched to and which have been flying around here for a few years already in testing. Updated MPCNC Brushed Motor Foam (Needle) Cutter. There aren't any exact dimensions for it but you want it to stick out of the guide as little as possible. Stick it on something desperately in need of decoration and peel off the transfer film: MPCNC Vinyl Cutting – crown on mug A LowRider can easily handle this size, is cheaper to build, and can be But they don't cut dollar tree foam board nearly as well as the needle cutter. More Recipe For Disaster. 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. Since the time I wrote this a couple of people have tried that and had good success with it. This past summer I ran the AC on low though and it didn't hurt my electric bill that badly. 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. I used the engrave option to generate toolpaths down the center of the lines with 6mm cutting depth to make sure it went fully through the 5mm board and then saved the resulting gcode to a SD card to load in the RAMPS LCD controller I use to control the machine. The foam cutter uses the simplest approach by taking advantage of the flexibility of the needle. It's fairly straight forward. Nothing major, but enough that I wanted to try the new version. Phase III will be a drag knife for cutting vinyl decals. So my initial needle broke fairly quickly. Wait until room temp before removing. The cutter works best with a motor RPM of around 6,000RPM and the optical tach is a great way to make sure you're at that sweet spot. Runner Up in the Design Now: 3D Design Contest 2016. 607. We've had quite a few discussions about other uses for the machines as well and lately have been experimenting with drag knifes for cutting vinyl decals and lasers for engraving and cutting wood and other materials. The speed controller came with the motor in a power pack setup from Flitetest.com which I bought when I visited their flitefest event last summer in Ohio and was used for a few rounds of aerial combat before being stripped out since I didn't have room to bring a plane back to AZ with me. 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. I also started cutting the velociraptor from the same designer as the T-Rex which was a 38 minute cut when scaled up...but had a small issue with my ESC shutting down halfway through. Support, Chain. about $20, but you probably have some of the parts already. Attaching the needle to the bolt is much easier than to a smooth bearing. Moebeast’s Foam Ripper contains an STL for the manifold vacuum nozzle, or you can build a square funnel shape from foam board. Oh...and also it can be considerably cheaper. 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. 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. Contribute to martindb/mpcnc_posts_processor development by creating an account on GitHub. It was your instructable I was reading on the train this morning. Get info of suppliers, manufacturers, exporters, traders of Needle Cutter for buying in India. While far from silent it's also considerably quieter than most low cost spindles. 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. I actually just finished putting a 2.8w 445nm laser on the machine - in fact I had to take a small break from dialing it in for various materials to get this written up before the deadline on the CNC contest! It creates VERY little dust and most of what it does create gets pressed into the waste board. He also used a 3D printed mount for the needle guide but had issues with the guide heating from friction and melting the mount. And I left some of the PLA printed parts in my truck (which I've literally baked bread and cookies in) as well as on a table in the backyard where they got full sun exposure. At least I can see the scrape so that makes sense ;) Need to do a bit better wire management and I'll be back in action. I have published a couple of versions my CNC sheet foam cutter attachment out on Thingiverse. Free shipping. I do plan on implementing the new default MPCNC mount, but since I haven't had time to upgrade my MPCNC to use that mount it's been on the back burner. When I finally add this style of mount to the customizable version I'm going to convert that from two pieces to one so it can print without support. David's thread on Flight Test is very active and where I learned about the needle cutter. Along with the spindle, cutter and laser the drag knife is nice for cutting vinyl (burning vinyl with the laser releases poisonous and caustic chlorine gas which isn't good for you or the machine) and a pen holder is nice for drawing plans/adding decorations. Having seen several mentions of foam cutting machines/methods in this forum, this might be of interest to some of you... especially RC folks. The two big limits on speed are the way it's geared and how stiff the machine is. 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. Personally I don't care for the undercutting. My plan of building on the dining room table wasn't going to work. vacuum pad solves both problems. 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. I found mine worked quite well as it was. (Lipo cells are 4.2 volts fully charged / 3.8v nominal - the Xs notation indicates how may cells are in a pack. That would hold the foamboard down. Washers must be small enough to not touch the outside (moving) part of the bearing. You can build the cutter for 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! To fit 20"x30" sheets of foam board I had to build the machine 3' x 4', Once I test assembled it it was obvious that this was way bigger than I had mentally envisioned and I had to face the dilemma of where to store it and use it! Just pay attention to the direction of the coils on the needle and the crankshaft so that the crankshaft will self tighten and the needle will bounce off the crank instead of getting caught on it if it rides up. It is important on a project like this to get the dimensional accuracy of all parts as close as possible to avoid assembly and operational differences (problems). After some experimenting my cuts continued to improve...but fairly quickly my needle broke right where the coil was that mounts it to the crankshaft. 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. But they seem to generate more friction and don't dissipate the heat fast enough. 87. more space for a M6 stop nut. I saw the MPCNC on Thingiverse a few weeks before you posted on the FT forums about your needle cutter but dismissed it. 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. may have poor resolution, and the RPM may hunt or surge. Though strength isn't really my concern. They cut the top paper fairly clean, but then just sort of slowly melt through the foam which results in a lot of under cutting and a sloppy cut. So my machine finally works and works rather well. Some people have switched to using 1" OD stainless tube which is considerably stiffer, I'm considering that when I reprint the new style parts since rigidity does become a major concern on a machine of this size. Read more. 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. Great project, I'm intrigued with the idea. full power for a second to suck the work down, then reduce to minimum power. What do you think? I left the bottom open so it just sucks itself down to the table. Phase IV will be a needle cutter for foam core board. You also inspired me to do some more cutting and show the machine in action a bit better. I also plan on using PLA instead of PETG for the rebuild because my temperature tests over the summer convinced me that the parts would hold up fine in my shop. This thread also includes his walkthrough of building an MPCNC and several other user builds and foam cutting information: http://www.rcpowers.com/community/threads/mostly-p... David also has a thread on Open Builds discussing the cutter and featuring more user builds: http://openbuilds.com/threads/brushl...eet-foam.58... RC Groups also features a thread David started which includes another method of monitoring the needle speed using an inline tach instead of an optical tach: https://www.rcgroups.com/forums/showthread.php?256... Oddly enough the thread David started on the official MPCNC forums about his needle cutter is the least used...but here it is for reference as well: http://www.vicious1.com/forum/topic/mpcnc-based-fo... Bottom line is there are tons of people building and enjoying these simple needle cutters so if you have any issues getting one up and running there are a number of sources you can turn to for assistance! feedrate (mm/min) of ONE-TENTH the cutter speed. With the needle fully extended I slowly lowered my z gantry until the needle just barely scraped the surface of the board. Not entirely sure why but it actually made a very big difference. That's always fun! 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. 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. 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! You will probably need to adjust it to get a good fit to your motor. "Cutting foam sheets... with a needle!" You deserve the CNC prize, IMO! Is the tubing you chose galvanized steel? 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. basically a very fast reciprocating needle – like a sewing machine – mounted on your CNC machine. Thanks for sharing the whole process. Alright - now...let's build a CNC machine to mount this thing on first! Thanks for that detailed and useful reply about tubing! . One person found this helpful. the motor bearing. I got my original EMT from Lowes and it was very dull - but very smooth. With the cutter finished mechanically it was time to wire it up and test it out! OpenFlexure. First v2 attempt failed pretty spectacularly. Place it on baking paper and put in oven for 60 mins and then allow to cool slowly by turning oven off. 3 Axis Laser CNC Engraving Machine PCB Milling Wood Router Cutter GRBL 5500MW. This is such a cool idea. Get Contact details & address of companies manufacturing and supplying Needle Cutter across India. Support, Chain. Do this by preheating an oven (or toaster oven) to 80C (180F). Aviation. 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. Recipe for Disaster. I am the developer of the brushless-motor needle cutter for RC foamboard that has been mentioned/discussed numerous times on the V1Engineering (formerly Vicious1) site and in lengthy threads on the Flitetest forum and others. Ending Jan 1 at 1:55AM PST 6d 9h. $529.99 $ 529. That is indeed the corsair, I've yet to actually build it (want to finish the vac table to get a cleaner cut first) but I've always had a sweet spot for Corsair's. The new parts make for a stiffer machine but I haven't had time to reprint mine and upgrade yet. Most tattoo artists use a few rubber bands to pull the needle shaft in towards the tattoo gun. 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. I set it back up the way I had been going and pointed the tach...only to see 16k RPM read back at me! On the servo tester I was at about a 7 - I ended up having to dial back to 2.5 to get it down to 6k, no wonder I was having so many issues! Only 2 left in stock - order soon. If your flywheel is The needle cutter has none of these drawbacks. These planes in particular are a fascinating part of aviation history, and our own family history now too. The white foam reflects too much of the lasers energy. Home. Score cuts are no problem. I highly recommend the MPCNC and needle cutter as a low cost but high quality way to cut foam on a machine. 1122. I chose to 3D print my cutter. While I was printing my machine David continued to improve his cutter design. MPCNC Build. But finally gave in and spent the $13 on an optical tach. DOWNLOAD Thingiverse. Looking at the video again now it's obvious even at regular speed that the crank was deforming from the high RPM's. 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. So I dug in on building a MPCNC. Start manufacturing today with the 8' x 4' CNC Router Kit 16-20mm Rails and Ball Screws. (Since the very first test I've always worn eye protection and a full face shield while testing and would strongly suggest doing the same!). This is a standard example sketch that ships with arduino and basically works the same as a servo tester...just a bit more cumbersome. 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. Once it's mounted on the crank I cut it off so that with the crank at it's lowest position (deepest cut) I have enough needle sticking out to go completely through my foam board and just one or two mm's into my waste board (I use pink insulating foam from the hardware store as waste board - but more on that later.) 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. It could probably be done with annealed parts...but due to the shrinkage I'm not sure it would be worth the effort. It should then be easy to add the tach to marlin. ;). 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!) 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. 24.12.2020 - Entdecke die Pinnwand „CNC“ von Pixonaut. My concern is that I live in the desert and my shop where the machine lives gets REALLY hot if I don't run the AC in the summer. Still, my printer was new and that's a LOT of printing to build that machine. 381. Then, the world got turned upside down and the final touches actually got put on hold for a bit. About: I enjoy all kinds of DIY, Craft, Technology, and construction projects. 1200KV means that this motor will give 1200RPM for every 1V of power it's supplied at full throttle. You and dkj4linux were my bookmarks for the needle cutter. This involves swapping the Dewalt router for a 2.8 watt laser diode for engraving and cutting. My first attempts were a little jagged, but shortening the needle and sharpening it quickly improved that. Woah, that's a bit more than the 6k I was aiming for! Corner Guide MPCNC Needle Cutter. The flywheel is identical to Edward's version. start the machine. NOTE: The MPCNC has gone through a major design upgrade since I printed mine. But I measured with the paper so I like to keep it. If you don't want to keep the paper on the foam you could also just peel it off to free the parts as the foam is fully cut it's just the bottom layer of paper that is still somewhat holding together. I'd actually wanted a CNC machine for much longer, well before I got hooked on RC planes. MPCNC Build. Finally the needle cutter also excels at fine detail on both inside and outside corners - again due to the tiny size of the cutting tool. What finally convinced me that it wasn't the design of my crankshaft (I had gone through half a dozen revisions at this point) was a video of a needle getting tossed. plastic mount, and the bending load on the needle can break it at the top. $1,055.00. Weitere Ideen zu cnc, 3d cnc, cnc holz. At 8000-10000 rpm you David went back to his original air inflation needle and I followed. It looks like the governor stuff in blheli will do what I want, I just need to find time to play with it. The needle cutter works best with a feed rate of about 600-1000 mm/min, David suggests and RPM of 8k-10k to go with those speeds...but I've found 6k works best on my cutter. The MPCNC is a modular design with interchangeable toolheads. I've built a couple of the planes from Flitetest, including the Corsair (hard to miss the pattern in your intro!)
