Step 7: Response!

I am looking for some opinions, as this is my GCSE Technology PCB, as well as being useful otherwise. I would like some opinions about some or all of the following things if you are able: 

if you've made it, does it work/problems/general feedback/pics
refinements that could be made
aesthetics/ergonomics - does it look good/is it easy to use
is there any better way of actually manufacturing it?
any other comments

Thank you very much for your time. 

<p>Can I use that to control 4 stepper motors whitout the servos?</p>
<p>Hi I'm a beginner. Looking for help to create servo shield. Could you please give more details about controlling servos with L293D &amp; Shift Registers? How many servos at max arduino &quot;nano&quot; can be control using L293D &amp; Shift Registers?</p>
<p>What would it take to control 3 steppers instead of just the one stepper motor?</p><p>Also what level of power can the board drive?</p><p>Would love to use this to control a DIY CNC </p>
<p>Hi I specialized in the series, FPC(http://product.xindabest.com), etc are all we are good at, can contact us directly (http://product.xindabest.com)</p>
<p>AWESOME-Ness!!! Much Thanks for this. I dont know if ya answered this already but, can this do without the potentiometers?...I dont really get what theyre for and would rather get another servo line in there in place of...?</p>
How much current are you planning on pushing through those traces?
One question : how can we put our logo in eagle pcb layout?
Can't remember XD I think there was an import option, or a ULP? (forgotten the acronym - the library code thing).
:D great ! btw nice work!
Where are you going to post the code?
Hi, <br><br>You could have finished your board by cutting to shape with a junior hacksaw (this is how I do it even with GRP boards) and filing with emery cloth held on a flat file. It is not much slower than using a disk sander and is more controllable. Also rounded corners, while not important, would make it look a little better and show that you took a little bit of pride in your work.<br><br>Instead of using a laser to mark the component side a nice professional finish can be achieved with the 'toner transfer' method followed by a spray varnish - not cellulose base as the acetone thinner dissolves the toner - use an acrylic based one or a clear, water based brush-able one.<br><br>I like the etched logo, looks professional, pity the AW didn't turn out well. You could have filled the spaces with resist as that would use less etchant and allow notes to be etched on the copper side of the board.<br><br>Hope this is of use, best of luck with your project.
Interesting, but it is more a 'how do I make a PCB' than how to make a stepper motor shield. Even a picture of the circuit wld have been a plus
There is a picture of the schematic on the first page, as well as the eagle file.
tnx, apparently i missed that
Thanks for the replies guys, but try not to get dragged into arguing! I didn't see any real reason to get it sent off; it's a single sided board that is a one off production, and it's far more accurate than using the CNC milling machine. It would be really great if I could have some more general feedback, but thanks!
A better way of manufacturing it would be to send the files and have someone make them. Seeedstudio is by far the cheapest and easiest(that i've found).
True, but where's the fun in that? Etching is pretty cheap and simple and this board would be a perfect first project to hone your skills.
I know but he asked a question so i gave him an answer. And a first etching project i think should be something someone would want todo not just something easy
