Abstract

Described herein are ECAM systems and methods of operating such systems or, more specifically, methods of determining the spacing between build plates and printheads before deposits contact the printheads. A method may comprise positioning a build plate and a printhead (e.g., comprising a copper deposit) at a set orientation relative to each other and for some time (e.g., to allow changes in the electrolyte between the build plate and the printhead and/or changes to the printhead's electrode surface). Thereafter, a measuring voltage is applied between each pixelated electrode of the printhead and a measuring reference plate (which may be the build plate or another plate) while obtaining one or more current values. These current values are then compared to the calibration data set to determine the distances between this electrode and the build plate or, more specifically, the deposit on the build plate.
