What does in mean: CNC?
Posted by dtpostel 6 years ago | last reply 6 years ago
Does anybody know if there is a small, personal CNC in the range of under $1000? I do not feel I am ready to make my own, though I know there are plenty of 'ibles about them that I'm sure are good. I am looking to purchase a CNC, software, cabling, bits and all. Is there even such one as cheap as this? if so, where would I find one?

Hello , I own an automotive upholstery shop. I would like to start mass producing customs seat cover. In order to do so i need a machine that can cut identical patterns from vinyl and sometimes leather. I'd like to be able to scan the pattern (a cardboard template) and the CNC machine make the clean and precise cuts to the fabric. Could someone please help me!!!

I purchased a HobbyCNC EZ Driver Board from hobbycnc.com and I have some questions on how to use it. The instructions say that I need to use a power supply that can provide 50% of the TOTAL current draw of the steppers. It also says that a 2.5A stepper will draw 5 amps. So if I have 3 steppers that say 1.3A on them does that mean I need a power supply that can provide at least 7.8 amps or? And finally, it says I have to adjust the current coming from the board to each stepper. It gives the equation: desired amps times (X) .14= Vref. So since I have steppers that say 1.3A on them do I use that for desired amps or am I supposed to use double that?????? Anyone who has used the HobbyCNC EZ Driver Board, PLEASE help I am very confused.

Papa is looking into getting a CNC machine for his business and asked me about what to get. I looked into it for a little while but really I have no clue what is going to be needed. We receive imprints (negatives) of people's feet in a floral-foam like substance and normally clean it up a little and pour a mix of plaster into it to get a positive mold, which needs intensive course and fine sanding in a sink, (as well as adding things like metatarsal pads and other custom things depending on the order) and from that point the ordered material is vacuum formed over and the rest of the insert is made. Because of the shape of the feet and added features, it seems like we could cut out the use of the heavy plaster entirely if we use a 3D scanner to scan in the molds and then mill them out with a very basic 3 axis CNC out of cheaper/more light material for the rest of the processing. The question is, what equipment will be needed? I see some of the cheap 3D scanners are really nothing more than glorified webcams and fancy software, while (guessing the much better) laser scanners are pretty $$$. So how can we scan these imprints into the computer as a 3D file? And what are some good cheap CNC machines that can do the main 3 axises and enough to do 6 to 10 molds at a time?

Hey I'm preparing myself for building a DIY CNC MILLING MACHINE. right now I'm at the "shopping" part of the project- buying parts (motors, drivers, misc. electronics) can you help me buy give me a hint of what I need (preferably EBAY links/ prices)? requirements for the machine: - MUST be able to mill/cut (stainless) STEEL (time is not a concern so it's ok if it runs slowly as long as it's able to make a (small)stainless steel part) - would be nice if I could run it manually aswell (no computer, no cnc, just hanles or remote controller) WHAT DO I NEED?: - would this http://www.ebay.com/itm/321060801150?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2648 be sufficient? - what do you recommend for the spindle? (is there anyway I can connect a professional servo motor? as I might have one of those) - was thinking square steel profiles for the frame, what do you recommend? - for starters I cant afford ballscrews so I'll use trapezoidal treaded rods, other sugestions? - any thing else i need to know? - thanks!

Hello! Everybody. Please I need your urgent response. I'm trying to make the 3d CNC milling machine displayed on the home page, but I mustn't be shy to say it on the roof for that I need technical assistance. All I understand is how to put up the physical components, pls I need assistance on the electrical aspect of it, the programme that will be controlling it and how to command it to mill a particular Job. Thanks

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 have been interested in CNC for a while now, and now that I have a fairly good supply of money I think it's time to try my hand at building one. My criteria for the CNC are: *It has to be smallish (about 20" deep and up to 36" wide...) *I don't want to do too much precise cutting as I don't own a bandsaw. My cutting methods are hacksaw, Miter Saw, Jigsaw, and Circular saw... A kit would be nice (as in one with all parts included like the one oomlout will eventually come out with...) *I would only use it for foam most of the time, but it would be nice to be able to cut and carve wood and other materials as well. *A Hotwire machine might be nice... *I would like to build my own controller for it, because the prebuilt ones are expensive, right? *I would like it to have 30 inches x travel, 20 inches y travel, and up to 6 inches z travel. Like I said, it will probably do sheet foam most of the time, so even 6 inches or less z travel would probably be fine. Any of these sizes could be adjusted, I'm not set on the exact size... This machine would have to be able to work off of free or relatively inexpensive software. It would also have to be able to be stored 4 inches off the ground. I might bring it up to my benchtop when I use it, but it would be nice if it could stay down there on the shelf.

I have a Robo 3D R1+, and am about to mount a rotary tool flex shaft on the carriage, other than mounting the dremel what other changes need to be done. My biggest concern is the software, mattercontrol is what I'm using atm (the stock software that came with it). some of you may wonder why or what I'm going to do with it, yes, 1) because 2) whatever I can do with it. (to clarify further, will I be milling pcbs or making neet figurines out of brass, aluminum or wood?, yes to those as well)

I have been researching CNC milling online at metal-craft.com and other sites. I want CNC milling for the removal of metal by feeding a work piece through the periphery of a rotating circular cutter. But, I did not know the difference between CNC milling and CNC grinding and which one is suitable for shaping a material, Does anyone have any suggestions for CNC machine that would meet these needs? Thanks.
Um two questions whats the difference between a cnc milling machine and cnc router is it that the mill moved the work and keep the tool stationary and the router moves the tool and keeps the work stationary and the next question is which do you think is better to build i want one for mainly small gears and pcbs to make a larger machine and some gearboxes?
