I solved this with electronics... you can use QPDT switch and suitable wiring (I didn't have it at hand then). I have the 9V battery inside housing for 10 years, and it is still OK.

Thanks Bojan,
Yes I have implemented dynamic braking. It was very easy as I used a L298N DC Stepper Motor Driver Module Dual H Bridge Control Board.
By manipulating the I/O pins, you control how it works eg: dynamic braking, standby mode, speed (pwm), and motor direction. The module was under $5
I like what you have done without a micro, I'll have to look into it a bit more.
Cheers,
Damien.
Yes, great for when there is no PC. It is the Stepper motor controller.
Cheers,
Damien
