What does in mean: CNC?
Posted by dtpostel 6 years ago
I've been threatening myself with thoughts of building a small 3 axis CNC machine for a few years now. Although I've done some research on it, I don't understand what software takes a 3D model and spits it out to control the motor circuitry? I'm hoping that some kind soul will help me get this concept, it's the last part of the machine that I need to know about before I can start. I've seen lots of instructables on building the CNC machine, but am struggling to find any info on the control software. Here is the 3 axis CNC process as I understand it , please correct me if I'm wrong: 1. Model is designed using software like Blender, 3Dmax, and so on 2. ??? Magic software takes this model and translates it into tooling paths 3. ??? Magic software converts tooling paths to control pulses. These pulses are sent over the parallel port. 4. Control circuitry receives the control via the parallel port and sends pulses to the coils of the stepper motors, moving the tool carriage and cutting the model. 5. Much rejoicing. Bonus Question Parallel ports are lame. How could I use a hip young USB port? My best guess is that the magic software can be configured to spit out over a usb port, and then an Arduino could be used to receive and process it into pulses for motor control? Extra Super Bonus Question What's a "G-Code" and where do I get one? Thanks in advance for any light you can shed on this!

I was wondering if it would be worthwhile to try to make an electric pump or electric motor for a CNC machine (printer or mill) using a CNC machine. I know motors are mainly metal, but as long as the heat does not build up, the casing should be able to be plastic or whatever material, right? Some copper wire and a magnet should be the only resources else than the building material and the motor could be of a unique design since it would be made by a CNC for a CNC.

Hi, I saw this post at instructables about building your own cnc machine at home and i pretty much got interested.I have just few questions though. Can i make a medium sized cnc machine using that method ? Are there any standard dimensions for the cnc machine or i can use my own ? I am new to G code so where should i start to learn ? Which material is best preffered for a medium sized(should fit on my desk) machine ? Sorry if these questions sound a bit odd to you but i have no knowledge about cnc. Thanks

Which CNC build is the newest and most successful? Many of the ones I have seen are many years old and the technology keeps improving and I would like to give it go building my own, but I am not sure which design is the most straight forward and durable.

Hey guys, Ive been looking at a lot of the CNC projects and I really want to try something of my own. I could really use some good reading material on basics of building a CNC. I would like to build a 2 axis CNC for laser etching/cutting first and work my way up to a 3D mill. I could really use more info on the following: -How to properly use screw threads (bearings, mounting, etc) -Limiting factors to CNC strength (I would like to mill Aluminum eventually, what will I need? Just a higher torque stepper motor?) -Other important tips in designing and building my own. Feel free to just post links and ill look more into it. Ive seen a couple decent sites but a few of them werent free.

I am in the process of learning SolidEdge V19 by myself (It's CAD program, if anyone is wondering). Now I know it may not be the best place to start learning CAD, but I got it for free. I am quite new to CNC machining and CAD software and I need some clearing up on a subject: In what environment do I need to draw the parts in order for it to be used CNC? I am only working with sheet metal and have all the precise dimensions of the parts that need to be cut out. Should I create the parts in the drafting environment and then export it as a .dxf file which will be used on the CNC? Sorry if my question sounds a bit, you know, stupid, but I just need some clearing up on this issue.

Hi, Wonder if anyone can help. I remember sometime in the last 3 years there was a competition where one of the prizes was a cash voucher for a machining service. Like Shapeways but for CNC machining. Just wondered if anyone remembers what the service was called? I have been asked to re create a spinning wheel and thought it would be cool to use there services for a part which would be very difficult for me to make otherwise. Any help would be ace. :)

Hi, I've been digging around for material suppliers for machinable plastics, foams and metals (aluminum, copper, brass). I found McMaster-Carr and got great service and it is next day delivery, but shipping can be expensive. Amazon has acrylics and other polycarbs at sometimes reasonable prices. Who do you use as a supplier and has it been a good experience? Thanks, Andy

Hi y'all from France! I've been aching to get my hands on a CNC machine from quite some time now, unfortunately I'm quite a noob when it comes to electronics and such. I'd found that while the machine itself is not that hard to build (see all the ables), however the electronics involved are just too complicated for me to build a controller from scratch. I've found the other day some seller on french ebay selling a complete controller without the power supply, so I've been wondering about it but am not in the position to fully understand that piece of equipment. So my question is: what do you think about it guys? Does it seems to be ok (BTW I've also found 3 NEMA23 stepper motors, precisely the same model as described in the specifications for the controller board on its seller's page)? For now I just want a three axis CNC machine capable of cutting polymer foam and soft wood, so I don't really need expensive and powerful stepper motors. Thx for any kind of input!

Hello, I work on CNC Alamode project, raspberry pi and Alamode is configured to control 3 stepper motors: My configuration: Raspberry Pi Alamode (Arduino compatible), 3 stepper motors and 3 EasyDriver. Everything works, grbl is ok. Here is my story: I wanted to install a homing system, I first started with the x axis, as in the drawing, it worked well, it has stopped the motor, but I realized that the current 5v passed directly on Limit X (D9), without 330 Ohm resistance. Then I put this resistor like a drawing but now the homing no longer works. My question is: Have I damaged my card, knowing that everything works? Can I redo my original configuration without resistance? My last statement : 4.96 Volts between limit x (D9) and Ground. Thank you for your help. http://www.exonet3i.com

Hello, Still in research mode for my own CNC machine which will be Arduino based. But, as everyone is using different motors and controllers (drivers?), how do I choose the right one for me? My machine should be able to do soft materials like wood and plexi/acrylic but I als want to be able do mill/cut aluminum, as I am restoring an old car and parts are not easy to get hold off. For my board I was thinking of an Arduino UNO (like most) but then, which motor to go for? Uni or bipolar? 17, 23, 34? And which driver? gShield / CNC Shield V3 / Dual step driver? A4988? 1 board per motor or can I combine them? How to get a smoother run then 1/8 steps? (Found CNC Shield V3.0 + UNO R3 + 4pcs A4988 Driver for £15???) I have never soldered anything, but I am a fast learner. So far when it comes to electronics, I managed to hardwire a stereo without harness into my car, speakers, radiator fan circuit and some door controlled LED's. Far away from soldering of building a CNC, but I am up for the challenge. I know there are a lot of questions in this post, but I appreciate any explanation why someone chose one motor over the other etc.... Any information is highly appreciated. I rather research more then building something and then have to start over again. Kind regards, Red

Ok guy's i need a little help, or to be pointed in the right direction, backround: i want to buildd a retrofit kit for a existing automatic sandblast curtain.. reason: basically every monument company in the country own's an older automatic blast curtain, that is controlled by limit switches only, and the new ones are cnc and cost 50,000 ish, and the existing machines are screeming for a retrofit kit... i own the "hirons model j" automatic curtain, it an x,y easy as pie thing, my problem is that i can get the parts machined and the rig built, however the g-code is my problem, and i think it will be very easy for someone whom can do it, to do it.. all i need is the machine to make strait passes left to right and back while slowly progressing top to bottom and back, the nozzle will also have a "spindle" motor, that will make it make a circular pattern constantly for the duration of the job, could anyone help with the g-code, ???? i can do all testing as i own the machine,

To anyone who read my previous post about the CDROM stepper motor wiggling and not moving while being controlled by GRBL and the EasyDriver motor controller, I got that same motor to work. What I did was I completely took off the wiring system of jumpers I had made. I took off the male pins and kept only that. Then, I tinned four new 22 AWG stranded wire (which is a larger gauge than I was using previously), attached the male pins to one end, and soldered the other ends to the motor directly using copious amounts of flux and verifying resistance continuity between all wires and connections. My Take Away: A. The previous gauge wire was too small, B. My splicing of the wire failed miserably, C. The solder pins were in fact touching each other, shorting the system I am guessing that a combo of all three (honestly, mainly B) caused the frustration. Now it is one solid wire from motor to breadboard for each of the four connections. I believe by unsoldering everything and cleaning it up fixed the wiggle jiggle of the CDrom motor. So if you are having these problems with your CDrom motor/ motor controller, check the wiring and the solder joints. I hope this helps anyone having these problems.

I have been having intermittent problems with my cdrom stepper motor. I had a four pin motor soldered to a bare copper wire. I used the pins not the little ribbon cable and I left the ribbon cable attached because I figured, as soon as I snip it off I would regret it later. The other end connects to a breadboard that is in line with the stepper input to the EasyDriver motor controller. I have been using GRBL controller on my PC and when I tested it the first time in a vertical position it would just wobble around, not moving up nor down. I thought the stepper motor was bad so I got another one. The second was wired the same way, 4-pins, and it worked in the vertical no problem. Then later, while working on the rest of my project the second cdrom motor that was working did that same wiggle without moving up or down. I realized that the solder connections were very close together and that two pins were electrically connected. I modified the wire to basically a homemade male to male jumper wire. The extra pin made the room I needed to unsolder the two pins. Once again the motor worked up and down with no wobble. I have done nothing to modify the cdrom stepper any further and went to test my motor today after a couple weeks hiatus and once again, wobble with no up nor down motion. At this point I am stumped. I have reason to believe that my solder skills are lacking and that my homemade jumper has broken internally inside my shrink tubing where I cannot immediately see it but If anyone else has had this problem and knows how to rectify it please let me know. I hope there is enough info here laying out my problem and that someone can lead me in the right direction. If it also helps, I have checked my pin out and I do not feel it is backwards or crossed. I checked the resistance between the four pins and the end of my "jumper" and is approximately, 40, 20, 40, 100 ohms for A-, A+, B-, B+, respectively. I am really not sure what these number would mean but my buddy told me to check the continuity from end to end.

I was wondering if a water/air powered CNC machine would be feasible. Such a power method would allow the device to be powered by an outside compressor or pump or something else that supplies a flowing (pun) source of air/water. This would allow the only parts needed to be inside the CNC machine to be made by a CNC or small electricaly driven control valves and maybe some potentiometers for position sensing. I have noticed that most of the CNC plans that I see use stepper motors which if I understand right offer only 1 speed, but I do not really understand why. Please tell me what you think. I have been looking at these "build your own CNC printer" and "build your own CNC mill" sites alot lately, but I have no clue yet when it comes to such things.

I'm planning on building a X-Y CNC machine. The issue is softwares. My plan was to get 2 scanners, and rip out the stepper motors. Then, as seen on an instructables, use a parallel port with 2 or 3 ULN2003 chips to control the motors. My idea was to do as they did, and use TURBO-CNC to controll the parallel ports, unless there's something better to use? Can TURBO-CNC read G-Codes? If so, what is the best program to use for creating G-Codes? This project is starting with a 1W blue laser as a etcher / paper cutter CNC. It it going to be used for getting my machine tuned up. Once things are in good order, It's going to be turned into a 60W acrylic / 1mm aluminum / thin wood cutter.

Does anyone have any information about the three programs, Simple CNC, Simple Art and Simple Engrave. I went to the website, and there is an order page, but the contacts and support buttons are dead. There is no way to get in contact with them. Before I checked this I actually ordered Simple Engrave and was told I would receive an invitation to the CNC forum. But I have not received the invitation and have no way to contact. And of course, no program since it has to be downloaded from the forum. Should I just start a grievance with Paypal?

Hey so iv got this slightly damages USB joystick sitting around my house and it struck me that it could possibly be fun to turn it into a little CNC rig. Figure since its already got usb control to some degree it would simplify things alittle. So what I was wondering was is there some complication that makes this a bad idea that I am not seeing. Thought I would ask before rip the thing apart.

Hi there! What common material is best for off-the shelf rigid rods/bars for things like 3D printers and CNC machines? I'm actually thinking about making a 3d pantograph for expansion/reduction of originals sculpted in epoxy, (perhaps to be added/linked with a print/machining rig later. I see a lot of what seems to be steel tube or rod in people's projects, but steel is bouncy. Is there a particular cast or extruded alloy of steel or aluminum? Cast iron? Bronze or brass? I don't have a machine shop or a lot of money, so I have to use stock material or salvage, and I'm not so sanguine about salvage for this most critical element of the machine. Any thoughts? Thanks!

With a lot of old electronics lying around, I embarked on taking them apart with the intention to use the sled motors to build my first CNC. Unfortunately, I found only 2 wire DC Motors with limit switches on the laser sleds. Here is a list: 1.Sansui DVD with Sony Laser Carriage- 2 wire sled motor with Limit switch 2.DVD player from 32cm Bahun TV -2 wire motor with limit switch 3.CD Drive from Dell Laptop -Miniature motor with LS & 2 track ribbon connectors. 4.Mitsumi 31/2" Diskette drive -Stepper with less travel The only 4 wire stepper motor was on the diskette drive. Is it possible to use the 2 wire DC motors in my project? What sort of logic control will be required. How did they function in the DC/DVD drives?

I am thinking of running machine shop training courses in the UK for those interested in learning how to really use lathes and other big shop equipment. The idea is subject to insurance company permission etc. but I wanted to gauge if there was any potential interest from people here (obviously only those based in the UK, unless you really want to commute) I'd expect costs to be something like 50 GBP per day + materials, and no more than two or three people per session, keeping the ratio of machines to people as 1:1. We'll probably try and do "group projects" as well as bring your own. The idea of group projects is that every ones gets to make more than one of something, to get techniques sorted out, and then we combine everyones work into assemblies - collaboration at its finest.

I have a theory that I would think should work, but opinions are good. If I was to get a powerful laser diode, like 300mw, and machine out a holding device for it to go into a CNC millers collet, then wired it up to a power supply, and put it in a CNC machine.... Would I have a half ass laser etcher? I would have to manually turn the laser on or off, and the feed would have to be really slow, but would I be at least able to engrave stuff?

Hello all. I am looking for a cheap cnc controller, and came across this on ebay. It comes from china, but it looks like it is a good controller. Now before you suggest I look on Instructables, let me tell you I already have. I've also built a cnc controller from an instructable with no luck, which is why I'm going to buy one now. So do you think this is a good deal? Do you think it is not a piece of junk? Please let me know, I don't wan't to spend $188.09 on something that won't work. Your input would be appreciated. Thanks.
