Abstract
A method and system of facilitating development of fluids having a variety of elemental compositions are disclosed. A graphical user interface allows user interaction with a lab deposition system to control fluid drop ejection of fluids through multiple nozzles. Fluid drop ejection and drop formation can vary from fluid to fluid, and require adjustments to waveform parameters of a drive pulse applied to the multiple nozzles. The system implements a drop watcher camera system to capture real-time still and video images of fluid drops as they exit the multiple nozzles. The captured drop formation of the fluid drops are displayed to the user, and based on the images the waveform parameters are adjusted and customized specific for individual fluid. In addition to adjusting the drive pulse that effects fluid drop ejection, a tickle pulse can also be adjusted and customize to prevent clogging of the nozzles.
