<p>The Belt has teeth that need to engage the teeth of the hobbed gear on the motor, just like in the preassembled Y-axis. The teeth have to go aim to the "inside" of the loop. This way, the belt will not slip on the motor side and the movements will be repeatable.</p>

<p>What is the correct orientation for the X-axis belt? </p>

(Asked by: username_0 on 2019-11-11)

What is the correct orientation for the X-axis belt?

I first thought to place the smooth side down to match the tensioner bearing, but then changed it to match the motor pulley.
