    Hi there,

    I am designing at the moment a new printer. Rather than ordering a few closed loop belts to see which one fits, is there a way in fusion 360 to work out the belt size based on the distance apart of a 20 tooth and 40 tooth pulley for the GT2 belt?

    If so I would love some hints please as I do not have the pulleys just yet.

    Thank you.

    Using pitch diameter on the gears should work but it's far easier (and definitely more reliable) to use - SDP/SI eStore.
