Abstract

See full text

Systems and methods of controlling movement of a moving part of an applicator for jetting material from the applicator are disclosed. The method includes actuating a piezoelectric device operatively connected to a needle by providing a voltage waveform to the piezoelectric device, such that the needle translates along a positional path in a first dispensing operation. The method also includes sensing positions of the moving part over a period of time, where the positions define a time-dependent positional profile of the moving part, and receiving parameters for a second dispensing operation. The method also includes determining a required voltage waveform to be applied to the piezoelectric device to perform the second dispensing operation, and adjusting the voltage waveform provided to the piezoelectric device to match the required positional profile.
