⬢This is the end of the nextruder cable bundle we are going to attach to the Nextruder in the next step. It consists of a cable connector, a flexible plate and a semi-transparent PTFE tube.

⬢Using the T10 screwdriver, 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.

⬢Make sure the part of the bundle with the cable and the connector is facing the top of the extruder; as seen in the picture.

⬢Using a T10 screwdriver, tighten marked two screws on the inside of the extruder.

⬢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.

⬢Attach the cable connector into the top of the nextruder.

⬢Insert the semi-transparent PTFE tube into the fitting on the extruder. Push it all the way in.

⬢Good! Your nextruder assembly is ready to be installed.

⬢Manually lower the heatbed.

Because we will handle tools and the extruder above the heatbed, it is necessary to protect it. An empty Prusament box can serve this purpouse.

⬢Place the empty cardboard box approximately to the front center part of the heatbed.Move the XY axis forward.

⬢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.

⬢For the following steps, please prepare:

⬢Single tool extruder assembly (1x)

⬢From the extruder body, remove 4x M3x12bT (countersunk) screws using a T10 screwdriver and set them aside. You will need them in the next step.

⬢Attach the extruder assembly to the X-carriage. See the correct orientation of the extruder.

⬢Hold the extruder in place and secure it using two M3x12bT screws and a T10 screwdriver in the top two openings. Do not fully tighten the screws yet!

⬢Add the two remaining M3x12bT screws into the lower openings in the X-carriage to fix the extruder assembly in place using a T10 screwdriver. Do not fully tighten the screws yet!

⬢Tighten all four screws in a diagonal pattern to secure the extruder assembly using a T10 screwdriver.

⬢Attach the x-carriage-cover onto the X-carriage. Press it in unti it clicks in.

⬢Turn the printer around so that the PSU side is facing you.

⬢Locate the long metal profile (tch-mounting-insert) in the back of the top extrusion. It has five threaded openings in it.

⬢Place the xl-dock-cable-router (the plastic part) between the rear metal sheet and the aluminum extrusion.

⬢There is a screw protruding from the xl-dock-cable-router. The screw must be attached to the third threaded opening on the long metal profile. Look through the rear metal sheet to check if the cable holder is lined up with the correct opening.

⬢Push the 2.5 mm Allen key all the way through a hole (bottom left in the pattern) in the rear metal sheet as well as through the plastic part until you reach the screw. Tighten it up.

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

⬢Insert the M3nEs nut into the vertical extrusion on the rear of the left side.

⬢Connect the filament sensor cable into the filament sensor assembly.

⬢Move the filament sensor assembly to the top of the extrusion and align the M3nEs nut so that it aligns with the opening on the filament sensor assembly.

⬢Attach the filament sensor to the M3nEs nut using the M3x12rT screw and T10 screwdriver.

⬢Insert the PTFE tube from the extruder into to the first collet on the rear of the filament sensor assembly.

⬢The antenna connector is prepared by the manufacturer:

⬢The antenna connector has to be assembled by you:

⬢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.

⬢Connect the extruder cable to the upper slot labeled DWARF 1.

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

⬢Locate the Wi-Fi antenna connector on the right rear corner of the printer.

⬢The antenna can be rotated around and bent in two directions.

⬢We recommend pointing the antenna straight upwards.

⬢Now skip to Step 26 - Assembling the spool holder: parts preparation

⬢Remove the nut with the washers from the antenna connector.

⬢The antenna connector is prepared.

⬢The latest version of the connector has a thicker washer. We don't need it anymore. You can throw it away.

⬢Insert the antenna connector into the same-shaped hole in the Wi-Fi-antenna-holder .

⬢Push the antenna connector through the Wi-Fi-antenna-holder.

⬢Insert the thinner washer back onto the connector.

⬢Using the universal wrench, tighten the nut on an antenna connector.

⬢Good job! The Wi-Fi antenna is prepared.

⬢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.

⬢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 remove it from the printer. Tighten the screws.

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

⬢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.

⬢To make things worse, we have a new spoolholder for you.

⬢Versions:

⬢Version A: Printed spoolholder

⬢Version B: Injection molded spoolholder

⬢Position the printer so that the left side with the Filament sensor is facing you.

⬢Insert the M5nEs nut into the front support extrusion (with the orange plastic cover on its front). Insert the side with the spring (metal plate) first, then push the nut inside.

⬢The M5nEs nut is free to move up and down. You can adjust the spool holder’s position as you wish. The nut must be slightly pushed in to move smoothly. We recommend positioning the holder approximately to the height as seen in the picture.

⬢Insert the spool-holder-base into the spool-holder-slider. The narrower part of the base should go in first. Push it all the way in.

⬢Attach the spool-holder to the spool-holder-mount.

⬢Insert the M5x85 screw into the spool holder assembly.

⬢Carefully turn the printer so that the side with the side filament sensor is facing you.

⬢Insert the M4nEs nut into the front support extrusion (with the orange plastic cover). 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.

⬢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.
