Step 10: Tall posts oh my!

Now it's time to glue
the 1 1/2"x16"x1" posts to the z axis acrylic top
and then after your done with that, you then glue it to the base.

Required Materials:

Quantity Type Cost

4 1 1/2"x16"x1" Scrap

So I was wondering what type of step motors do you recommend (nema 23 or 17)? And with that being said how many? Plus with the step motor drivers, which do you recommend? I'm trying to get the electronics first then build the rest and I'm new to this and any help would be great!
<p>I asked for help for the electronic circuit to continue assembling a CNC machine from the old scanner<br> Thank you, my respect<br> Darmawan<br> Bali Indonesia<br> dmd190259@yahoo.com</p>
<p>Very nice write up! www.cncmakerzone.com is offering a free cnc machine for anyone interested!!</p>
So, I've read all of the comments on here and can't figure out why Bipolar Stepper motors would not be better than Unipolar stepper motors since most people said they wanted more speed and power. Why are Unipolar stepper motors recommended by you Techbuilder? Is it just the increase in circuit board complexity and price?
so do anyone have the electronical part? would be so good if anyone can make it
Can we use this information to build a 3d printer?
<p>sure, if you have the right technical skills you could definitely do this, just modify the place where the dremel is supposed to go with an extruder and a few other 3D printer related parts!</p>
<p>oh, and the software / calibration would be a little different as well.</p>

Did you ever get the kits started?

<p>Great tutorial! Just wish the electronics section was finished...</p><p>I found a cheap controller on a Chinese site: <a href="http://www.banggood.com/5-Axis-CNC-Breakout-Interface-Board-For-Stepper-Driver-Mach3-With-USB-p-81074.html" rel="nofollow">http://www.banggood.com/5-Axis-CNC-Breakout-Interf...</a></p><p>I have no idea how to make it work though...</p>
<p>You don't want that. You want something like this: <a href="http://www.ebay.com/itm/Arduino-CNC-Shield-V3-03-GRBL-compatible-Uses-Pololu-Drivers-/281670664172?hash=item4194e13fec" rel="nofollow">http://www.ebay.com/itm/Arduino-CNC-Shield-V3-03-G...</a></p><p>You can order all the individual parts and save about $10 if you want, or just buy that kit-type-thing with all the parts. I have one I use on a laser engraver, and it works great.</p>
<p>Hi.</p><p>I would also be interested in a kit. I am disabled so even the small DIY things can be difficult to accomplish. Always wanted a small cnc for woodwork. LOve your work :)</p>
<p>You mentioned using unipolar stepper motors, does this include the 5-wire stepper motors found in old PC floppy and hard drives? I have a whole box of these. Most other projects require 4-wire bipolar steppers. </p>
Hi you mentioned earlier kits, did that ever come to fruition? If so how much<br><br>Thanks
<p>Nice. How big is the area you can actually move in the x-y-axis?</p>
<p>electronics soon to come?</p>
the mechanical parts of a cnc machine like this is the most difficult part. its easy building stepper motor drivers and a microprocessor controller. you can even find software on the internet driving it.
<p>would a printer with a built in flat bed work?</p>
<p>Hi,</p><p> Thanks for posting such a wonderful project. But I am confused that how to wire the electronic components and computer to this machine. Could you please make it clear?</p><p>saha.dev44@yahoo.com</p>
<p>good</p>
Cool. I might try this one.
<p>can not</p>
OK I have taken my share of scanners and printers apart, and I know that the stepper motor pictured in step 5 did not come from a printer or a scanner. Where did you get it?
I got it from an old epson printer sorry to disappoint you but it was from a printer
WOW thats a huge motor to come out of a printer! I need to find one of those...
1 1/2&quot; x 1 1/2&quot;is big to you?
Well apparently the images are misleading. Even if they are small, they are definately bigger than the ones I pulled out of my printers.
Never assume by a picture unless you have a reference point<br>like a ruler or a quarter so fourth.<br>You could also check the dimensions in step 3<br>
<p>umm</p>
Alright...but are those steppers strong enough to work properly? Could you provide the brand and the ratings for them please???
They were minimal at best probably enough to cut through some foam and light plastic. you can only get so much torque out of a little printer motor without sacrificing tremendous speed. <br><br>I no longer have the cnc machine anymore I sold it <br>so I can't really provide those specs
i have 3 cd drive lens assemblies (EG: the lens shell holder, the rods, the stepper motor and the base)<br><br>could i use those to make this?
<p>umm</p>
you just have to check if the stepper motors are uni polar or bipolar. both will work, but they require different circuit boards. other than that I'd be worried if they are strong enough, but hey, worst you can do is try and they break
<p>so good</p>
<p>Good idea trying with this material. I think it would work best for small machines as it is flexible.<br>With this in mind, the drill stand frame is poor design. First its poles are way too high. The link between the drill stand and the frame of the machine should be as short, strong and direct as possible. <br>The other axis seem to be less fragile but could be improved.<br>Gluing : Not good for precision and stops you from dissassembling if you need to transport or repair the machine.<br>Lastly, nothing is said on how things are aligned perpendicular and parallel.<br></p>
$20 for anyone who has hundreds of dollars worth of scrap perspex lying around...
<p>I don't know where you are buying your acrylic from but I have loads, about 6 kilos in weight and its cost me little over &pound;10!......... ebay, just look for off cuts</p>
<p>haha! I thought the same. One man's trash is another man's $300 project. Still a nice simple build. </p>
<p>word</p>
<p>is this a dead project. I see no link to the electronic portion, and the author said he was going to post those 4 years ago.</p><p>What gives???</p>
<p>nice</p><p><a href="http://myhomemadecnc.blogspot.com/" rel="nofollow">http://myhomemadecnc.blogspot.com/</a></p>
nice and green!
where is ghe electronics instructable?
When is the electronics part ever going to come out?
nice anvil in the background there
How big of an object can it cut?
Where can I go to find scrap materials? Is this a junk yard or a specialty store kind of thing?
