Hi, I would like to know if it is possible to use one reader to record fingerprints say at a security desk then use several others on doors and machines to recognize the fingerprints.
This would require that the unique ID generated by the first one was the same as the ones generated by all others. Does anyone know if this is possible?

I have tried with 3 different servos (high torque metal gear, $2 micro servo and some standard plastic gear servo) and had the same outcome with all 3. Huge offset from desired location with gains of P300 D600, or massive out of control oscillations with P600 D2000. Integral control is what is really needed but it still does not appear to work. Derivative control only makes the control worse above about 800 (suspect its due to increased noise when taking derivative). Any help would be much appreciated.
Has anyone else had problems selecting suitable gains for the openservo, The servo either overshoots or has lots of steady state error. Also Integral control does not appear to work, the motor does not move with just integral control. I am using the pre loaded firmware
