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 Prusament box can serve this purpouse.
⬢For better access to the X-carriager in the following steps, manually move the heatbed down.
⬢Attach the steel sheet by first aligning the rear cutout with the locking pins on the back of the heated bed. Hold the sheet by the front two cutouts and slowly lay it down onto the heated bed - watch your fingers!
⬢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.
Be careful that the springs and pins do not fall out when handling the parts.
⬢Line up the screws in the Tool Changer Lower Lock assembly with the blind holes in the X-carriage. See the correct orientation of the part. Use the U-shaped groove in the part.
⬢Take a look at the X-carriage from the rear side.
⬢Attach the Tool Changer Lower Lock assembly to the X-carriage and secure it with two M3x12cT screws from the front side. Ensure the correct orientation of the part.
⬢Attach the Tool Changer Upper Lock assembly to the X-carriage from the top and secure it with two M3x12cT screws from the front side.
⬢Attach the x-carriage-cover on the X-carriage with the hole up.
⬢Push the center of the cover using your thumb. The cover will then snap into the latches on the X-carriage. You will feel a light "click" when it is successfully snapping.
⬢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.
⬢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.
Check the position of the long metal profile, it must be positioned on the far left.
⬢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 dock is a press fit, so the screw needs to be tightened very hard.
⬢The following instructions need to be done correctly and carefully. Achieve better understanding and successful assembly by watching the video alongside the guide.
⬢Place the second Nextruder on a box and guide the cables on the back side of the printer.
⬢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 second 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 dock is a press fit, so the screw needs to be tightened very hard.
⬢The following instructions need to be done correctly and carefully. Achieve better understanding and successful assembly by watching the video alongside the guide. Watch this prusa.io/XL-dock-installation.
⬢Carefully turn the printer so that the side with the Wi-Fi antenna and side filament sensor faces you.
⬢Insert the M5nEs 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 M5nEs 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.
⬢Insert the second M5nEs nut in the extrusion approximately to the same position as shown.
⬢Attach the spool holder assembly to the M5nEs nut in the extrusion. Note that there is a protrusion on the spool-holder-mount, which must fit into the groove in the extrusion.
⬢Tighten the spool holder assembly.
Do not use the spool holder as a handle!
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.
⬢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.
⬢Insert the second M4nEs nut.
⬢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.
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.
⬢Attach the spool holder assembly to the M4nEs nut in the extrusion. Note that there is a protrusion on the spool-holder-mount, which must fit into the groove in the extrusion.
⬢Tighten the first spool holder assembly.
⬢Assemble the second spool holder and attach it to the lower M4nEs nut with an M4x12 screw.
⬢Congratulation! Your Original Prusa XL is ready to be fired up!
⬢Compare the final look with the picture.
⬢Now, let's go to the last chapter 4. First run.
