Reminder: To handle the printer, always grab the handles on both sides of the printer. Do not lift the printer by the aluminum extrusions or the metal sheet profiles on top.
In the following steps, we will work with tools and install extruder above the heatbed, it is recommended to protect it against any possible damage. An empty Nextruder box can serve this purpose.
Place the empty cardboard box approximately to the front center part of the heatbed.
Manually move the X-axis assembly all the way to the front side of the printer.
Manually move the X-carriage approximately to the center of the X-axis.

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:
Insert the M3nS nut into the nextruder dock.

Push the nut all the way into the dock. If not use the Allen key to push the nut into the nextruder dock.

If you didn't find the nut, there is a spare in the Nozzle Seal Assembly package.

Carefully rotate the printer 180° so that the PSU (Power Supply Unit) side is facing you.
Locate the long metal profile (tch-mounting-insert) with five M3 holes inside the rear aluminum extrusion.
We'll use all M3 holes in the metal profile.
There is a screw in the long metal profile which is fixing the part during the transport. Keep the screw in the metal profile for now.
Maintain the position of the long metal profile for the next step. It must not move!
If the metal profile moves, just push it all the way to the left and fixed it with the screw.

Take the cable bundle.
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 M3 hole in the long metal profile (tch-mounting-insert). 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, the screw MUST be tightened firmly.
Repeat this step for the second tool head.

At this point you should have already installed two docks.
Locate the M3 screw in the metal insert.
Using a 2.5mm Allen key, remove the screw from the metal insert.
Attach the third, fourth and fifth dock the same way as a first dock.
The dock is a press fit, so the screw needs to be tightened very hard.
The attached docks have to look like in the picture
Good job!

Starting from May 2024, you may receive a gray nozzle seal. The assembly and functionality remain identical to the red one.
The following instructions are intended only for printers without pre-installed nozzle seals. If you have already installed the nozzle seals on the nextuder docks, go to Wi-Fi antenna holder versions.
For the following steps, please prepare:
Nozzle seal (5x)
M3x30 screw (5x)
Spring 15x5 (5x)

The current nozzle seal position is temporary, the exact height will be set in the next chapter once all the Nextruder parts are mounted.
The docks have a hole for a nozzle seal.
Insert the nozzle seal (with the spring) into the dock.
Using a 2.5 mm Allen key, tighten the screw so that the head of the screw is 1 mm above the dock.
Good! The first dock is ready.
Repeat this procedure for all remaining docks.
Wi-Fi antenna holder versions

Wi-Fi antenna holder versions
XL printers feature two distinct Wi-Fi antenna mounts: one located on the side and the other on the rear side of the printer. Before proceeding, carefully examine your printer to identify the type of mount it has.
Begin by verifying that the Wi-Fi mount is pre-installed on the side:
Side mount (Version A): For printers with the Wi-Fi antenna holder on the side, the antenna holder comes pre-installed by the Prusa production department. If your printer has this mount, proceed directly to (Version A) Connecting the nextruder cables.
If the Wi-Fi mount is not pre-installed on the side:
Rear side mount (Version B): If the Wi-Fi mount is not pre-installed on the side, your printer may have the rear side mount. In this case, the antenna holder is not pre-installed by the company. Navigate to Version B: Wi-Fi antenna holder: parts preparation to install the holder and antenna.
