Hi, the jitter problem turned out to be caused by the DRV8825 stepper driver. Actually it just looked like jitter in the step generation. The driver could not drive the motor properly when set to low current (300 mA) at certain step frequencies (around 200 steps per second) in full step mode. After I sett the drivers to 1/8 microstepping the problems disappeared.
So far so goo, now I'll start looking into controlling my stepper motors from a Python script.
