Haydon-Kerk Idea Drive stepper motor controller
Notes:
- Microstepping down to 1/64th.
- Digital inputs and outputs (open collector).
- Microstepping waveforms are in the audio frequency range so the motor makes harmless squeaks and whines.
- Stopping the motor on a fractional step requires more hold current even if the motor is not under load. Stopping between a full step is effectively a holding load.
