⬢Side filament sensor assembly - right (1x)

⬢M3x10 screw (1x)

⬢M3nEs nut (1x)

⬢From the right side of the printer:

⬢Insert the M3nEs nut into the extrusion.

⬢Connect the filament sensor cable to the filament sensor.

⬢Insert and tighten the M3x10 screw using a 2.5 mm Allen key.

You should now have both Side Filament sensors attached.

⬢If you have older docks, attach them to the first and the second positions. Then attach the new docks from the upgrade.

⬢Place the xl-dock-cable-router on the bottom metal sheet below the aluminum extrusion.

⬢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.

Repeat this step for the second dock..

If you have older docks installed in the first and the second dock position, continue attaching the docks from the third position.

⬢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 current nozzle seal position is temporary, the exact height will be set later in this chapter.

⬢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.

⬢Locate the xl-rear-cable-management-plug (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.

⬢Loosen four screws securing the electronics cover. Remove the cover.

⬢Connect the first dock (from the right side) cable to the upper slot labeled DWARF 1.

⬢Connect the second dock (from the right side) cable to the lower slot labeled DWARF 2.

⬢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.

⬢Push the antenna cable through the opening in the cable cover (metal sheet) and guide it behind the cover to the electronics box.

⬢Attach the antenna-holder on the screws and push the cover to the left and tighten the screws.

⬢Connect the antenna to the apporpiate slot on the XL Buddy board.

Do not take the XL-splitter board out of the printer, the photo is only a tool for connecting the Nextruder cables.

⬢Connect the third, fourth and fifth (from the right) Nextruder to the splitter:

⬢XL-splitter with connected Nextruders has to look like this.

⬢Put the XL-buddy-box-cover back on the printer.

⬢Check Nextruders cables, they have to be inside the cutout in the cover.

⬢With a T10 key tighten the four screws.

⬢Locate the right filament sensor.

⬢Insert the first dock (from the right side) PTFE tube all the way into the upper hole in the part.

⬢Insert the second dock (from the right side) PTFE tube all the way into the middle hole in the part.

⬢Insert the third dock (from the right side) PTFE tube all the way into the lower hole in the part.

⬢Locate the left filament sensor.

⬢Insert the fourth dock (from the right side) PTFE tube all the way into the upper hole in the part.

⬢Insert the fifth dock (from the right side) PTFE tube all the way into the middle hole in the part.

This step is only for the printer, which has a Wi-Fi antenna on the back of the printer.

⬢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.

⬢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).

⬢Insert the third M4nEs nut in the extrusion approximately to the same position as shown.

⬢The M4nEs nuts are free to move, you can adjust the position as you want. But remember, the nuts 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 third spool holder to the M4nEs nut using a 4 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.

⬢Turn the printer, so the Filament sensor (with two PTFE tubes) is facing you.

⬢Insert the fourth and fifth M4nEs nut in the extrusion approximately to the same position as shown.

⬢The M4nEs nuts are free to move, you can adjust the position as you want. But remember, the nuts 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 fourth and the fifth spool holder to the M4nEs nut using a 3 mm Allen key. Note that there is a protrusion on the spool-holder-base, 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, third, fourth and fifth 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.

If you have an older version of the XL-dock-cable-router, follow the instructions for the new XL-dock-cable-router.

⬢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.
