Yes, as mentioned in the Update section of the documentation. The fix is actually done in the StepperMotor library I wrote. This is why your system is still behaving strange

Hi, I've just mounted my MiniEngine 2, but I'm not able to find the correct values for calibrating my steppers?

This is the spesifications of my steppers: Nema17 Stepper Motor DC 5V 1.2A 2-phase 4-wire 2.6kg.cm 1.8 Degree.
I'm using a 12v Power supply. and my motors are acting Perfect in other testarduino programs, I also use BED

Hey Lars,
if you don't installed DIP switches, the Big Easy Driver uses 1/16 steps.
So your calculation should be:
1,8 degrees = 200 full steps per full round.
With the MiniE you need 200 * 16 steps per full round.
To calculate your steps /cm you need the diameter of your toothed wheel.
(1/16 steps) / (Diameter * Pi )
Example:
3200 (1/16) steps / (0,12cm diameter * 3,14 ) = 0,3768 cm per full round of the stepper.

If your motor is not running by jogging it, use the potentiometer at the bigeasydriver, it helps me a lot!!

@Airic correct me if i am not right.

Thumbs up!
I'll add this formula to the documentation:

steps / cm = (steps per full rotation) / (Stepper wheel diameter * Pi )

Any suggestion?
Thanks.

Did you set the jumper 16-bit mode... Took me a while to figure out why mine wasn't working...
