The STEP_ENN is not there anymore. It´s now changed to a output with is triggering at the changingpoint of the waveform.
Please note that the Piezolegs is a friction based motor and you are never
know without feedback were the motor is.
You drive 10000 steps forth and back, then you are not on the old position.
Mayby you reach it with 5-10% accuracy. If you do this some times you absolutly don´t know were you are. (Its like a stepper with a frictionweel)
The Step and Dir inputs are inputs...
