19. Place an idler pulley into the hole on the Y axis.
Place FT3 over the idler pulley and one of the
screws in place. This will be removed later when
adding the belts. Repeat this for the other y axis
idler pulley.
20. Take a 5mm bore pulley and place it onto the
shaft of one of the y axis stepper motors. Lock it
in place using the two set screws. Repeat this
for the other y axis stepper motor.
21. Take the cable chain and split it in half (20 links,
note using more than 20 links will cause the
cables to be to short). Take one end and lock it
into the female cable mount on the x axis
motor. Lock the other end onto the male cable
mount on top of the hotend.
