I’m using 2X 6V 3,0Ah Sonnenschein dryfit A300 lead-acid batteries connected for 12V.
I had these batteries lying around in my “laboratory”.
The motors can take 6V normal 9V max and I have a software restriction in place to prevent using the motors above 9 volts.

The micro switch is exact enough to calibrate the Stepper but I must mention that I am using the Stepper with full steps (no half steps or micro stepping).

I’m not using a transponder (have no need for it yet) but maybe in the future.

Until next time, Greetings,
H.J. Windt
