Short answer
Genmitsu lists 42 mm and 52 mm spindle mounts for the 4040-PRO and says its Z carriage supports 65 or 69 mm motors with an extra mount, such as its 101-63-ZC65 or ZC69 holder. SainSmart's setup article instead describes a 44 mm sleeve inside the 52 mm mount; that conflict is unresolved. Genmitsu matches its dust shoes to the spindle diameter.
