Getting motion from a stepper motor?

[cropwell]

The Arduino is well supported at www.arduino.cc There is a library of prebuilt code for stepper motor applications. If I get the time and enthusiasm I need to get down and do a stepper controller for various jobs. John S, some time ago, indicated to me the desirability of a rotary divider with programmable angles. The application in this thread is another good idea that could be programmed in a day (if I were up to speed, which I am not at the moment). I have got a raft of other projects on the list and probably not enough lifespan left to do them (based on current list !).

Cheers,

Thanks, looking now.

It seems what i want is not a stepper controller but a ramp pulse generator - the stepper controllers seem to want to run the motor themselves but i have a bigger drive to do that, this just needs to generate the step pulses in a trapezoidal ramp form.
