Hi all

I am looking for a stepper motor controller with parallel/serial port
interface. Anybody know where I can find these?

Thanks,

Hi all

I am looking for a stepper motor controller with parallel/serial port
interface. Anybody know where I can find these?

Find an old floppy disk drive. The steppers that position the
heads have a simple interface that can be controlled by
a few bits on the parallel port. This assumes that you will
be using the floppy head steppers themselves. They are
not super-high torque or anything, but I built a little robot
platform (on a long tether for power and control from the PC)
that used two 360K floppy controllers and motors. mounted
on the sides of a cut-down floppy chassis with an added
3rd-wheel caster. My 10-yr old nephew enjoyed using a
little BASIC brogram to steer it around the floor.

Don't recall at the moment which Website had the connection
info, but if you Google on "floppy stepper" you'll probably
find it.

Best regards,

2 bipolar stepper motors can be controlled from the parallel port
fairly easily, the parallel port doesn't have enough power to drive the
motors directly (depending on your mobo and motor specs but generally
not) so you'll need to pick up a motor driver, a quad half H bridge
works well for bipolar. When I did it I used 2 SN754410NE from TI
(available in small quantities from digikey for $1.88US) to drive 2
stepper motors directly from the pc. Software for it is more work than
the hardware, you'll be doing the stepping manually driving each bit in
correct order, it's not difficult and can be done in simple scripts but
integrating into your application can be a pain. Datasheet is
available on digikey's site and would suggest you read it before laying
out your system but basically you tie the 4 Y pins to the 4 motor leads
and the 4 A pins to output on your parallel port (pins 2-10) supply
appropriate power and ground and you're ready to go. Let us know how
it goes for you.

Look at the various kits available from www.mpja.com
