"The motor does not rotate for each 5 steps and catches up at the 6th step"
welcome to microstepping, this is how it really works. (though the numbers look odd)
People presume that since they have micro stepping that they can position the stepper to any position of the (presuming 1/16th micro stepping and a 1.8 degree stepper) 3200 positions. This is not correct. The stepper is only stable for full steps, half steps and if your lucky 1/8th steps, beyond the limit of your stepper it just doesn’t move and catches up on the next value it can actually do.
If your needing real 3200 position steppers you need a mechanical gearing system
