The carriage should be in place and attached to the belt at this point. Slide the carriage up and down the tower to make sure the movement is free and smooth.

Slide the carriage all the way to the top of the machine and make sure it clicks the endstop at the top. You should hear the endstop click when it is slid to the top of the machine.

Repeat the belt install and carriage clamps to the remaining 2 towers repeating the motion test and make sure each hits the endstops.
