You could design your own driver, I will donate/supply the
controller ic and passives ....<br>
<br>
I have a bunch of these parts taking up space that I may never get
around to using..<br>
It would be great to see them put to a good cause... They are AMIS
30512...<br>
I also have a variety of power stages: MC33932, L293DD, L298P,
ULN2803 that could be used with a mcu to make a programmable stepper
controller...<br>
<br>
If someone is willing to design one for the purpose of donating it,
I'm all in on supplying the parts ...<br>
I'll even toss in an extra set of parts for whoever designs it, to
make one for themselves...<br>
Disclaimer: As long as the parts used are parts I have in stock, I
have a good bit of kit on hand, mostly smd...<br>

drawbot</a> is a total blast. I want to make more
of them and am looking at the different ways of
controlling steppers with the arduino.</p>

font-weight: bold; text-decoration: none;">Easydriver</a> is
one mechanism. They are about 15.00 each at
Robotshop. So that comes out to 30.00 which isn’t
too terrible. You can even run <a

75.00 to run a three axis CNC including the Arduino.
Not too bad for a small hobby project. But for
drawbot that’s a bit steep.</p>
<p>The Adafruit <a moz-do-not-send="true"

target="_blank" style="color: rgb(54, 93, 160);
font-weight: bold; text-decoration: none;">motor
shield</a> is a better deal for a drawbot. It’s
only 20.00 and it can run two servos and either two
steppers or four DC motors. Way more bang for the
buck.</p>
<p>What are good ways to get the price down even
further?</p>
