Hi!

I'm very confident about the linistepper! I made two of them on one board, for driving two floppy drive steppers. It is for use of a dual axis telescope drive (1:3000 gear ratio). I have modified the firmware to support only the microstepping mode and your special halfstepping mode. Microstepping is very accurate and what is more important, there are absolutely NO vibrations, which can be even more distracting than rough step sizes. For controlling the stepper board, I have made a very simple controllerboard, based on an 16F84. It operates the two motors independantly and is also able to be controlled by RS232. It is adapted to be used for a altazimuth telescope. However, it could be interesting for other standalone operations as well.

Kind regards,

Kai Ries
