Claim 0:
1. 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;
providing, based on the one or more images, instructions to a gantry, the gantry comprising:
a primary positioner that carries a first applicator and includes:
a first drive mechanism configured to move the first applicator in a first direction, and
a second drive mechanism configured to move the first applicator in a second direction, wherein movement caused by the first drive mechanism causes a corresponding movement of the second drive mechanism in the first direction, and
a carriage; and

a secondary positioner that carries a second applicator and includes a support coupled to the primary positioner at the carriage, wherein:
the movement caused by the first drive mechanism causes the corresponding movement of the secondary positioner, and
the secondary positioner is configured to move relative to the primary positioner in the first direction and the second direction;

actuating, by the primary positioner, the first applicator, in accordance with a first movement provided by the instructions;
dispensing, while the primary positioner actuates the first applicator, a first fluid from the first applicator at a first dispensing region of the first substrate;
actuating, by the secondary positioner, the second applicator in accordance with a second movement provided by the instructions, wherein the second movement causes the second applicator to move relative to the first applicator; and
dispensing, while the second positioner actuates the second applicator, a second fluid from the second applicator at a second dispensing region of the second substrate, wherein the second fluid is dispensed from the second applicator simultaneously with the first fluid from the first applicator.
