Use the first calculator on the page. 36T with "normal" motors and belts gives 44.44 steps/mm, which is an unusual number (to my mind), so I'd double check the belts and motors to make sure of their specs.
Typically for 200 steps/mm motors @ 1/16th microstep and a 2mm pitch GT2 belt, it's going to be 80 steps/mm for a 20T pulley, and 100 steps/mm for a 16T pulley.
