Repeat this step for both tool heads:
Using the T10 key, loosen the marked two screws on the inside of the Nextruder.
Hook up the keyhole openings in the flexible plate of the cable bundle onto the screw heads.
Using a T10 key tighten the marked two screws.
Make sure the part of the bundle with the cable and the connector is facing the top of the Nextruder; as seen in the picture.
The cable bundle must be installed exactly the same way as in the picture; with the cable on top and the semi-transparent PTFE tube on the bottom.

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 both tool heads:
Check that the M3nS 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.

The fallen nut may be in the Nextruder box. If not, use a spare nut in the Nozzle Seal bag.

Step 11 Preparing the printer

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.
Move the X-axis assembly all the way to the front side of the printer.
Move the X-carriage approximately to the center of the X-axis.

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.
We'll use the first two 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.
Place the first Nextruder on a box and guide the cables on the back side of the printer.
The nextruder can move when handling the cabling. Keep watching the Nextruder!
