Re: Stepper Controls

Dennis and all,

The card from Boondog is a parallel port card with 3 ports. Very easy to
use for
experimenting. Good documentation. URL = http://www.boondog.com

The stepper driver from Space Time Productions has been a disappointment so
far. The
card is well made but except for a schematic of the board, documation is
nonexsistant.
Simon has been good at returning my email questions, but his software to
run his
board is written in Forth. I have some 450 oz/in motors which need 3.5v @
3.5a that
I want to use on the bp clone. I have one installed one the X axis with a 2
to 1
reduction and the best table speed I can get is ~8 ipm. Pretty slow for
positioning.
I'm running it with a simple Qbasic prog. The timing loop is a short as I
can get it
without motor chatter (~60rpm). I'm open to suggestions. Simon's URL =

Dan Mauch's driver card would be great but I don't think it will handle
these low
voltage motors.
