Hi!
I've got the shield working, and have it attached to a €7, 48 step, bipolar motor. Everything works fine as long as I keep the speed below 25 rpm. Any speed over that just causues the motor to wiggle back and forth (is this whats called jitter??). Is this caused by my cheap choice of motor, or do the shield have a maximum operating speed?
I'm using the code provided on the ladyada.net/make page.

Maximum stepper motor speed?
