Hello stampers,
As I stated in a earlier post I had the same problems with the 5804 and the
stamp. I was wondering If anyone has ever designed a highend stepper driver
using the 5804, and might be interested in sharing drawings, code or anything
else that I might be able to use. I have designed a stepper motor driven saw
that feeds material into the saw then a air cylinder lowers blade and cuts
through material, then hits a limits switch and repeats until qty is met. Vb
sends length and qty variables to the stamp. Since I ran into such speed issues
i gave up on project and never completed the driver. If anyone is interested I
might be willing to fund a project by purchasing the parts and buying a couple
of proto boards from pcb express to build a highend stepper driver for the 5804.
Thanks Jim Gorbet

list who builds CNC routers and stuff. He would be a good source for info.

Don't remember the guy's name, but if you get on the chat list someone can
direct you to him.

I too looked into using a Stamp to drive a stepper project.
I quickly decided to go with an old 486 PC and off the shelf stepper
drivers.
As my recent threads indicated, you need power to run a stepper.
power for speed and power to do work. a 1.5v stepper @ 3 amps is
designed to be run at 30 volts. just check out the watts to the
motor when you keep the current the same. 1.5v@3A=4.5 watts,
30V@3A=90watts. Big difference in delivered power from the motor and
just as big a difference in motor speed.
then the speed of the signals. a uni-polar is a more common stepper
but is half as fast as a bi-polar. so running it is bipolar mode is
preferred. that means an H-bridge. very simple stuff.
then of course speed of signal, steppers do not run smooth at low
speed, or at high speed. so a microstepping drive is preferred.
figure 50khz is your target MAX speed. and I do mean max. steppers
lose power as they increase in speed, so it will run out of power at
high speeds. You will need some processing power to read your program
and run three steppers. one for each axis. I do believe that is a
bit much for a stamp.
for $100 each chopper style bipolar stepper driver(up to 7 amp), an
old PC, and a $10.00 software package, you can run a lathe or a
mill. Not as much fun as building your own. and if you want to go
cheap, you can save $10.00 and go with a free Linux software package.

check out the Allegro 3977 bipolare stepper dual h-bridge chip.
the down side is that it is surface mount, not through hole so it may
be beyond the ablilty of most to solder on a board. and unless your
motors are low power, it needs to be soldered directly not put in a
socket.
Also, any H-bridge circuit will work, making sure you eleminate the
dangerous regenerated voltage spikes when you switch leads.

I'll put some stuff together for you and send it to you off list. I
think that this is not a stamp application.
