Hello Dirk

I am now building the Stepper and have some question to you.

1. The connection "Aux" on the Atmel controller, what is this use for?
2. On the Flash elektonic diagram, is a transistor "TR1" wich type
can i use here, is a BC548B okey?
3. I use a 12 volt, 0,15A bipolar stepper, must i use a 12 volt
ekstern power, or can i use 9 or 15 volt?

At last, can you explain to me, hov are the stepper find the zero point, if you take all power away, and start up again. Do i have to set alle the parameter again in the router or will the controller rember the position of the stepper?

Best regards
