Thanks!!! 

Hi,

OutA goes to DIR+ and OutB goes to PUL+. 0V goes to DIR- and PUL-. 

200 steps per rev (which is typically minimum) is normally more than enough.

Hi jostein, how to connect the "signal" of microstep driver to your dyno box?

How much pulse/rev setup is good to control flow valve for hydraulic pump brake dyno?

Thanks

But you already control a RC servo motor ain't all the functions on you hardware/software already there.

Its just like building a BIGGER version of a RC servo motor utilizing a stepper motor with feedback for correct positioning ? YES or NO?

Cheers

Hi,

Yes, there are stepper motors with encoders. Indeed such devices work much like servos. 

You would need more inputs though and the setup is more complicated. Most stepper motors are used without feedback. It's ok as long as you set it up correctly.

Hi Jostein , nice work watched your youtube clip several times, losing steps is a concern ? I don't like the idea of loss of steps?

Why can't one use a  dual shaft_stepper motor and couple up a feedback Potentiometer ( rotary Encoder )  to prevent loss of steps

There are already made Stepper Motors with Encoders which don't come cheap but people can over come this via coupling a desired range rotary Encoder to a sized stepper_motor at a reasonable price themselves. 

Since you already control a RC servo motor ? why cant that setup be implement in the stepper motor with feedback ?

" RC servo motors are a gearbox/DC motor/PCB Controller/feedback Potentiometer  ???? "

Cheers

You are making a great work, hope soon I can test your device, keep on the good work  👍
