Claim 7:
8. A method for dispensing fluids by a dual dispensing system, the method comprising:
obtaining one or more images of a first substrate and a second substrate;
identify, based on the one or more images, a first location of a first substrate and a second location of a second substrate;
performing a height sensing operation to determine i) a first height of the first substrate relative to an XY plane and ii) a second height of the second substrate relative to the XY plane;
providing, based on the first location and the second location, first instructions to a gantry, the gantry comprising i) a primary positioner that carries a first applicator and ii) a secondary positioner that carries a second applicator, wherein movement of the primary positioner orthogonal to the XY plane causes a corresponding movement of the secondary positioner orthogonal to the XY plane; and
based on the first instructions:
actuating, by the primary positioner, the first applicator over the first substrate and dispensing a first fluid from the first applicator, and
actuating, by the secondary positioner, the second applicator over the second substrate and dispensing a second fluid from the second applicator,

wherein in response to the first height being different from the second height, providing second instructions, configured to adjust, using the secondary positioner, one of a first dispensing tip of the first applicator and a second dispensing tip of the second applicator.
