Stepper Motor Parameters

Archiver

Hello,

Last week I received word that my current ISA motor controller board
supplier was going out of business because they were outdated. (Alpha
Products) They control steppers using of all things - BASIC. How
terrible!

Got to get into something else. I stumbled across Parallax and Stamps
and my sense of it is that it would be a very good substitute to what
I am presently using and possible a whole lot more fun.

I see the small motors being controlled but can this small "genie in
a bottle" control size 34 or larger steppers? I'm using 300 - 600
in/ounce motors presently.

Please put my mind to rest before I spend the BIG BUCKS.

Thanks .... Jim Tooley

Jim,
You may find control is easy with the stamp. I use the stamp for three
stepper driven products. The drivers are another matter. Size 34 and 42
motors are usually not discussed by this group (at least in the few months
I've been aboard). For these projects, I have had good luck with Anaheim
Automation ( http://www.anaheimautomation.com/ ). They still support ISA
boards. They even have a product that does it with Basic.
Actually, my only problem with them is that they fall short with drivers
for the smaller motors ( size 6, 8, 11, 17 ).
Hope this helps,
Mike

I would suggest you take a look at the drives from Gecko Drives
(http://www.geckodrive.com ). Look at the G210. It is a step and direction
controlled drive that handles up to 80 V at 7 amps. Will handle NEMA 34
motors and even some NEMA 42. Very easy to interface to a Stamp with just 2
pins (or a PC parallel port). Cost in singles is only $129.

The Genie in a Bottle can do a lot of things. The problem is doing
things concurrently.


A friend has automated a small hobby lathe for thread cutting and
controls the X and Y axis and monitors the spindle speed. The speed
of the spindle feeds back to the X axis control for thread cutting.

The Stamp cannot continuously monitor the spindle speed, and X axis
posistion from the encoder, do the calculations and reposiston the X
axis in real time.
