Ok, thanks for your hints, this is what I tried now:
-Used a shielded USB Cable (cut the plugs off and soldered the mesh to GND) ----> No change
-.Used 100uF and 470uF caps (10 and 35v) -----> No change in behaviour
Grrrrrrr!1!111!!!!
I doubt that clean 5V could fix the issue, but it´s worth a try.. i only have a 7905 around, which makes -5V, but that´s ok, right?? If i just swap the poles??
I serously start to think that either my arduino or my ramps board produce this issue...
