The latest assemblies come with the nozzle seal pre-installed on the extruder dock. To confirm this, examine one of the extruder docks closely and compare it to the picture to see if the nozzle seal is already in place with the square nut. If not, continue with the text below.
Repeat this step for all tool heads:
Check that the nut is inserted in the Nextruder dock.

Make sure the nut is pushed into the dock all the way. If not use the Allen key to push the nut into the nextruder dock.

Carefully turn the printer 180° so that the PSU (Power Supply Unit) side is towards facing you.
Locate the long metal profile with five M3 holes inside the rear aluminum extrusion and slide it all the way to the left side.
We'll use all M3 holes in the metal profile.
Maintain the position of the long metal profile for the next step. It must not move!

Place the xl-dock-cable-router on the bottom metal sheet below the aluminum extrusion.
There is a protruding screw from the xl-dock-cable-router. Attach the screw to the first screw hole on the long metal profile. Through the hole in the rear metal sheet, check if the cable holder is lined up with the hole.
Push the 2.5 mm Allen key all the way through the hole in the rear metal sheet until you reach the middle screw in the xl-dock-cable-router and tighten the screw.
The dock is a press fit, so the screw needs to be tightened very hard.
Attach all the remaining docks using the same procedure
