[PD] stepper control

[Lucas Cordiviola]

Totally,

Martin suggested something using what Ray already had (arduino - L298), but these chips seems perfect.

You meant: (square wave) --> [dac] --> line out --> op amp --> Step (logic)

Right?

hello,

electronic circuit like :

[http://reprap.org/mediawiki/images/a/a3/0J4575.1200.jpg]<http://reprap.org/wiki/Pololu_stepper_driver_board>

Pololu stepper driver board - RepRap - RepRapWiki<http://reprap.org/wiki/Pololu_stepper_driver_board>
reprap.org
Please note: Pololu stepper driver boards has 0.05 ohm sense resistors instead of StepStick 0.2 ohm. A Pololu stepper driver board is a well known RepRap machine ...



or

can control the steeper in a more acurate way than what you can do with an audio amplifier.
(see datasheet for more info about the way this chip control a motor).

they are inexpensive and can easily be control thanks to a line out and small electronic circuit (OP AMP)

I think you will have better result using this dedicated chip than hacking an audio amplifier.

cheers
