Easy to Build Desk Top 3 Axis CNC Milling Machine

por
Destacado The Instructables Book Contest

Paso 4: The Y stage

The Y stage is just like the X stage but turned 90 degrees. Mount two rails and a motor on the X Stage and then take another piece of flat material and a U channel and make the moving Y stage. Make the little bearing thing and a coupling nut for it too. When your done it should look like this.

Hi Tom,

You've concieved of an amazing machine. My wife and I made a milling machine we call the ThrAxis based on your frame and stage design. I've written a blog post about what we built at http://itsprojectday.wordpress.com/2014/06/27/the...

Thank you so much for your inspiration and hard work getting this design made and documented.

You know, I started looking at instructables for CNCs about two years ago. I started building your version, then I saw the drawer slide version, then started looking at the buildyourcnc design. At one point I decided to try out a hybrid of the three and had the x and y axis going, but never finished the Z axis. After starting on a new version that was mostly based on the buildyourcnc design my family and I ended up moving across the country (south to north, not that it matters). I'm just now getting back to building a CNC, and although I won't be building your design I do feel that it is worth saying that your instructable was definitely an inspiration. Thank you.

Respectfully,

James

Is it possible to get software that allows me to hook this directly to a computer and have the computer direct the motor versus the computer sending data to a cnc 3 axis driver then to the motors?

just ran across this site and more specifically this design. what I'm looking for is a method of auto pick & place without draining Fort Knox! I don't have a lot of room to do this either and have relatively small PCBs (not motherboards) on my build list. and what impressed me here was KISS. using "skids"! now why didn't more people think of this? my requirements require only very light loading (the machine weighs a LOT more than what I'm working with) so this concept should work perfectly. before beginning though gotta take a look at this software. I run win7 out of a VM under linux so both OS's are available (but prefer linux). also need to purchase a parallel port daughter board (as my motherboard no gots). I've already built 3 unipolar motor drivers so all set there. I can also use my 10 amp bench power supply to power this project.

Wow, this is the easiest CNC milling machine design I've seen yet.

But, I have one major problem: Neither my PC, nor laptop has parallel ports, nor do I even know where to get a parallel printer cable in my country anymore. Is it possible to use a USB print cable instead, or perhaps even an Arduino? I've seen many 3D printer projects (but haven't built one yet) that use an Arduino to send the sketch to the stepper driver.

Please remember to always clamp your work pieces in a vice before drilling. Do not hold small pieces with your hand and drill. This can be an easy habbit to get into, but it can be a dangerous mistake that can cost you the use of your hand.

Yes the 3 axis machine as built in this instructable will do the same basic thing as those 3 axis machines on the link you provided. Although some of those machines have larger work areas, this machine can be scaled up to provide a much larger size of work area, albeit for about $20,000 to $40,000 less in price.

I created a similar machine and I used an AE-MDL-STPR811 board. It gave me by far the most torque power. The board also gives you the option of adding a surface mount heat sink, a fan and external Schottky diodes. I only added a surface mount heat sink because that’s all my machine required. The board also has jumpers, if you want to hard code it, or it can just be connected to all the controls signals by two .100” header connectors. Here’s more info about the board http://www.avayanelectronics.com/Products/AE-STPR8811/AE-MDL-STPR8811_Manual.pdf. I found some really cheap ones at DriverDudes.com, you can get just the board or have it fully assembled. Here’s the link to DriverDudes http://driverdudes.com/product_info.php?cPath=22&products_id=1

You do realize that theoretically you can calibrate by having the machine just mill the baseboard support using some large milling head, thus achieving a perfectly flat base? I guess this depends also on how much the machine changes when you move it from place to place...

with your cnc machine? I have a wedding coming up in a month and a half. I have full access to a great work room (family business) and I think I can source most of the materials from broken equipment around the warehouse, grainger, lowes, radio shack and a bunch of other places.

I would have to produce about 200 of them, obviously each with a different name and table number. Is it precise enough to make keep the writing looking smooth and will it allow me to import a basic font from a work doc?

It's pretty clear I have only conceptual knowledge of this stuff but I might as well jump in the deep end. Thanks.

destroyer2012
destroyer2012 dice: Mar 23, 2011. 11:35 AM
I built one of these machines and I must say that for cutting anything serious it is way too flimsy. I tried to face a small (1 x 0.5 inch) aluminum block and the results were fairly disastrous. The single pipe holding up the dremel mount skewed, and the the whole thing just wobbled way too much. I guess I could go slower but them making anything worthwhile would take ages. And the sound it makes with the dremel on full power is ludicrous.

Engraving things works great because you're basically not cutting very much at all, and it's just an exercise in precise positioning, which this machine does very well.

I tried PCB milling several times but the problem I keep running into is not having the board absolutely level on the xy stage. The commercial solution to this is to have an airhockey-style air levitation system attached to the cutter, so it's always the same height from the surface. It would be cool to implement something like this but possibly too complicated. What I haven't tried is screwing the board directly to the xy stage for machining ( I used a vise) but maybe that will work better.

Now I am working on converting this to a 3d printer, since it seems more suited for that task anyway.

Destroyer

My question is this: If one were to make the scale of the hardware larger so that it can deal with a great surface area of materials (I'm not too concerned with depth myself), would some adjustment(s) need to be made to the circuitry or programing thereof to account for the new sizes of the X and Y axes?

I've already been tinkering around with the software; I have a personal copy of Alibre, which can export SLA files, which I then convert to G-code with Freemill, and run through my (not yet existent) hardware with mach3. Everything seems to work fine, but I notice that Freemill makes a 'raster scan' of the object by tracing back and forth across the object, making its way from one end to the other.

I'm a little concerned about backlash with hardware grade nuts and all-thread feedscrews. I was thinking that, in terms of backlash, working from one end of the part to the other in one axis is ideal, but the back-and-forth scan in the other axis is far from ideal. (I'm figuring that the Z axis will probably be okay too since the tool has weight, which will probably always keep it preloaded it to one end of the backlash.) Do you suppose it would be worth investing in a high-quality feedscrew for one axis only, and making sure that winds up being the back-and-forth axis? The economy of this project is my favorite feature, but I'm thinking with that one upgrade I might boost the accuracy it achieves. What do you think?

Well this instructable certainly created a feeling of "love at first sight"

I dont have access to tools that would create the pipe frame from electrical tubing, but i wondered if the same frame could be made from 20 or 25mm copper water pipe and fittings, and the whole assembly soldered, what are your thoughts?

apache64 dice: Dic 22, 2010. 7:08 AM
I fell in love with the simplicity of this design and went out today and bought the pipework. Reading the threads i noticed someone asked about the backlash from the nut to screw thread. I found another DIY CNC machine where there is a good photo of it. Basicaly you need to put a spring in the way to tension the nut to the thread thus losing any backlash. this can be done either with two nuts seperated by some silicon rubber tubing, or a spring. here is a picture of a comercial one.

Hey Tom, I love your instructables on both the machine and the circuit. I have my machine up and running. in an attempt to improve its speed I want to go from 12v to 24v, I'm using 2 11w bulbs in parallel at 12v and I believe I'll have to go series to run 24v but will I need to double up the number of bulbs? course this will be tested after I get some backup bulbs but hoping to get an answer before I pop a box of bulbs again.

Secondly, am I correct in assuming that you can set the length of the axis rails and threaded bars to whatever drilliable area you need? I ask because I would like to make a 8.5 foot square CNC for making full size Grid Beam spars and building the frame to support the mechanism doesn't seem all that difficult. But I need a minimum of 8 feet square of drilliable area to do the hole grid correctly. Any advice?

You need 5-8 wire motors for this, or get a bipolar motor drive for 4 wire motors.

Those little motors won't pull/push much. I would be looking at photocopier motors atleast. Another great thing with photocopiers is there are allot of other goodies in them. Some have real lead screws, decent gears and belts. Most repair places are more then happy for you to take old dead units off their hands. Saves them from paying to have it hauled away.

A few nice additions would mean the difference between some of us newbies ever getting off the ground with this awesome project.

Davetech
Davetech dice: Ago 28, 2009. 9:35 AM
Lots of design programs have an output option that will create an outline of what you have drawn/designed. In Diptrace you can select an "Edge" output which creates a G-code file and saves it as a .dxf. Then you import the .dxf into your machine controller program (Mach, Cambam, K-Cam...etc) and use a "V" shaped engraving tool to mill the circuit trace outlines. If you are making a double-sided board, you have to set it to "mirror" the bottom set of traces and use a couple of reference points to exactly align the board when you flip it over to mill the back side.

I intended to make my own controller board but it was too complicated to draw by hand. I tried the toner transfer method with little success. I finally gave up and bought a new, already assembled Univelope driver board off eBay for about what it would have cost me in parts. It works very well. Several people on our forum use the "Hobby CNC" board kit and say it works great too. But to answer your question, now that I have a mill I use the trial versions of Diptrace and K-Cam (I'm poor, donations appreciated ;)

You might be able to use Arduino. The inputs are just step & dir.
You can use the same type output / transistor setup Tom used too.

I sell drives using PICs & ULN2064 driver
It's just a basic cheap 1.5A $50 drive.

I use Mach3 Ver 2.63 with my boards because they need a longer pulse & the older ver seems to work best.
Also you can use EMC2 for Linux, it's free.

What is the length of x, y and z axis pipes?
Davetech
Davetech dice: Ago 2, 2009. 3:42 PM
The length's are not critical. They will; however, affect the amount of working space you have. I guessed and bought 1" ID pipe, the two legs (y) are 10", the parts that join the Z-"T" (x) are 8" and 3" and the Z pipe is 10". I guessed wrong about the 1" ID because the thing turned out bigger than Tom's but I'm happy. It is Sturdy!
slider388
slider388 dice: Ago 21, 2009. 9:36 PM
Better sturdy than weak. What cutting area do you have? I'm thinking of scaling this up a bit to get a 12"x12"x3"ish cutting area.
Davetech
Davetech dice: Ago 23, 2009. 9:01 AM
My work area is X-12", Y-8" and Z-5"
slider388
slider388 dice: Ago 23, 2009. 1:29 PM
wow thats pretty good. The Y in this design is kinda limited by how far out from its support you mount the z module, but I'm aiming for you area or a bit bigger.
Davetech
Davetech dice: Ago 24, 2009. 1:54 AM
Yes, you are quite correct. If you try to extend the Y out too far, when the stage traverses very far from the X rails, it will tend to tip. I overcame that problem by pouring a 6 pound lead counterwieght that rides on the X stage. I was worried that the lead weight would make it hard for the rails to slide but since I used channel steel riding on steel conduit for rails, the additional friction was minimal.
Davetech
Davetech dice: Ago 24, 2009. 1:59 AM
The easier approach, of course, would be to use longer black pipe "legs" to make the X stage wider, but I was past that point by then and just made the counterweight instead.
slider388
slider388 dice: Ago 24, 2009. 7:49 AM
Thanks for the heads up, I think I'll go with some 18" legs. When you say you used 10" pipe for the Z, do you mean that you put the z module 10" above the rest of the frame or do you mean you extended it out 10" over everything else? If not, how high up did you put it and how far out? Thanks!
Davetech
Davetech dice: Ago 25, 2009. 7:02 AM
Upon re-reading I realized that my response missed the gist of your comment... I answered about extending the Y axis, but you commented about the placement of the Z axis upright. Here's how I built mine. But if I were to use a little longer extension than the 3" nipple. I'd get more useable workspace. I might do that. With this size pipe, it might even be a good idea to point the "T" towards the rear and put a pipe and elbow so that the Z upright is further away. I constantly have to be on guard against my Y stage colliding with the upright. In the picture you can see the counterweight. The rubber bands keep it from walking around due to vibration. I used rigid 1/2" copper rails for the Y stage because I ran out of steel conduit. It works well too. What looks like blown fuses are actually ballast lamps. Looks like I may be running them a bit hot.

slider388 dice: Sep 5, 2009. 7:02 PM

Great Idea, would like to build, what is the software that drives the mill? Hopefully it's as cheap as the machine.

Hi!

Kcam looks OK, there is a crippled Shareware download, http://kellyware.com/kcam/

How much torque should the motors have? I plan to use the machine for making PCBs so will be a similar size to Toms.

I have been looking at:

and

Big thanks Ed

Hey Tom, nice work, what software are you using for this CNC and where can one obtain such a software package?

I can't seem to find the view all comments link on the page anymore. I got a lot of my questions answered by viewing all comments and using the ctrl-f key to find key words. it is a lot easer that scrolling through 50 pages. if someone else has it could they post a shortcut for me please? it would be greatly appreciated.

UPDATE: I also have three Vexta pk268-01 2 phase, 1/8" step stepper motors. I don't know much (well, almost nothing), about CNC but love the concept of creating your own tools and parts :)

What kind of materials can be used with your CNC milling machine? Can it also cut through metals? If yes, what kind? I have an old Prolight program, will it work? I also have IronCAD, but I don't know how to work it and don't have the manual for it. Another program I have is Mach... but i have the same problem (no manual). Where can I find these manuals? a Manual for Solidworks?

Ok here is a idea built from stock useualy cut only on 2 sides... Take a 12x12 sheet of steel... 10x10x1 delrin sheet set the delrin on the steel. 1x1 steel squair tube... put steel shims on top and bottom of squair tube to give it some room... put steel rod over end of derlin and steel bars this will hold the delrin slide down... Then a delrin spacer and table for that axis... this seems to be a way to make a strong table from the shape that comes from the factory & your useing your slides to set your rails... less adjustment....

Delrin / Acetal is EXPENSIVE. That would cost about $100 USD I use scrap HDPE for my mill parts, same size less than $20. UHMW about $35

Tom you did not mention anything about the motor specifications ... what kind should i get ?
josheeg
josheeg dice: Abr 2, 2009. 8:55 AM
It would seem it could be lower cost yet if 2 materials were used UHMW (Ultra High Molecular Weight) Polyethylene Sheet for the ends of slides and Squair steel tubing a drill press with a counter sink some taps some bolts and nuts..... the same lead screw being threaded rod but washers and nuts on the ends for end bearings... a drilled block with screws could support a plastic loop. it would be stronger and more rigid and made squair like legos...

Here is my mill I guess its not cnc and does not follow many of your design concepts but you inspired it!
