Notes Before you start:

• The drag chain end links are shown as a part separate from the drag chain, you will find them however already connected to the ends of the drag chain. You may remove the end link and install it as shown here, or leave it on the chain and install as once piece at a later point.
• The M5 threaded hole in the eccentric nuts is offset from centre. It's helpful to mark the closest side with a marker, shown below in red, as it's difficult to identify the short side once installed.
• Install the eccentric nuts into the X Carriage with the shortest side (which you have marked) facing the bottom of the X Carriage
