Cheap N Easy

[magicniner]

A chain can be a length or a loop real easy. Belt not so much.

A belt can be used as a cut length as easily as chain, if you need a continuous loop then you will need to use an off the shelf size which can mean you need to make your mounts to allow adjustment of pulley spacing, but smooth drive, lower energy losses, and reduced wear and maintenance really can make the effort worthwhile,

Yeah I hear the looped belt i know you can by them presized. That's my issue right there as i would have need to buy several due to how i don't plan most things. Hey it's how i work!

The chain however i can shorten, lengthen, loop or otherwise with ease. the CON being finding sprockets for the Stepper.
