⬢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.

⬢Locate the Wi-Fi-antenna-holder (cover) on the rear of the printer.

⬢Loosen two screws on the cover slightly. No need to remove them completely. Push the cover to the right and remove it from the printer.

⬢Connect the first Nextruder cable to the upper slot labeled DWARF 1.

⬢Connect the second Nextruder cable to the lower slot labeled DWARF 2.

⬢Attach the cover to the screws. Push it all the way to the left and tighten the screws.

⬢The antenna connector is prepared by the manufacturer:

⬢The antenna connector has to be assembled by you:

This step is only for the printer, which has a Wi-Fi antenna on the back of the printer. If you have the antenna on the side of the printer, proceed to the next step.

⬢Locate the Wi-Fi antenna connector in the middle of the printer.

⬢Screw the Wi-Fi antenna on the antenna connector. The antenna can be rotated around and bent in two directions.

⬢We recommend pointing the antenna straight upwards.

⬢Turn the printer, so that left side is facing you.

⬢Insert the PTFE tube into the middle slot in the filament sensor.

⬢Insert the first Nextruder PTFE tube all the way into the upper hole in the part.

⬢Insert the second Nextruder PTFE tube all the way into the middle hole in the part.

⬢Locate pins two pins on the spool-holder-base and line them with the rails in the spool-holder-slider.

⬢Insert the spool-holder-base into the spool-holder-slider and push it through a little through the part.

⬢Insert the M4x12 screw on the longer side of the 3mm Allen key.

⬢Insert the 3mm Allen key with the M4x12 screw through the assembled spool holder to the prepared hole in the spool-holder-base.

⬢The M4x12 screw has to protrude through the spool-holder-base.

⬢Carefully turn the printer so that the side with the Filament sensor (with 3 PTFE tubes) is facing you.

⬢Insert the second M4nEs nut in the extrusion. Insert the side with the spring (metal plate) first, then push the nut inside.

⬢The M4nEs nut is free to move, you can adjust the position as you want. But remember, the nut must be slightly pushed in to smoothly move. Anyway, we recommend approximately the same position as you can see in the picture.

⬢Attach and tighten the second spool holder to the M4nEs nut using a 3 mm Allen key. Note that there is a protrusion on the spool-holder-mount, which must fit into the groove in the extrusion.

Keep in mind that if you mount the Spool holder too high or too low, it may not fit the filament spool on it. There has to be enough space around it.

⬢Take the Nextruder and place it carefully next to the dock.

⬢Place the two metal inserts through the white holes in the dock. The magnets will help you dock the Nextruder.

Check that the Nozzle seal lightly touches the nozzle.

⬢Well done, the first Nextruder is ready!

⬢Connect the second Nextruder in the same way as the first.

⬢Assemble and connect all Nextruders.

⬢Good job!

⬢On the Nozzle seal heigh calibration steps we used docked Nextruder without the printer for better visibility, proceed next steps on your printer. Do not dismantle the docks.

⬢In the next step, we'll calibrate the height of the nozzle seal.

⬢Using the 2.5 mm Allen key, tighten or untighten the M3x30 screw to calibrate the height of the nozzle seal.

⬢Proceed to the next step.

⬢If is the Nozzle seal too low or too high, we need to reposition its height.

⬢Using a 2.5 mm Allen key:

⬢The correct position of the nozzle seal is when it isn't bent and is touching the nozzle.
