The following instructions are compatible with Original Prusa XL Multi-Tool and Single-Tool.

⬢All necessary parts are available in our eshop prusa3d.com.

⬢This manual is compatible with the Original Prusa XL Enclosure.

We will demonstrate replacing the Main cable connector cover on a printer without the XL Enclosure for better visibility. There is no need to remove the XL Enclosure.

Do not discard any removed parts unless prompted to do so.

Step 2 Tools necessary for this manual

⬢For the following manual, please prepare:

⬢Torx T10 screwdriver

⬢2.5 mm Allen key

⬢A cardboard box for use as heatbed protection during the assembly. We will use the Nextruder box as an example.

Step 3 Unloading the filament

⬢If you have loaded the filament, unload it from the hotend. On the screen, navigate to Filament -> Unload Filament.

⬢Remove the filament from the hotend. It is is necessary to completely remove it from the printer.

WARNING: The hotend and heatbed are very HOT. Do not touch these parts!!!

⬢Move the Z-axis down. On the screen, navigate to Control -> Move axis -> Move Z.

⬢Cool down the printer. On the screen, navigate to Preheat -> Cooldown.

Wait until the hot parts are cooled down to ambient temperature. It takes approximately 10 minutes.

Step 4 Unpluging the printer

⬢Turn the power switch OFF (symbol "O").

⬢From the rear side of the printer, unplug the PSU cable.

Step 5 Protecting the heatbed

Before you proceed, it is recommended to protect the heatbed.

⬢Make sure the heatbed is cooled down to ambient temperature. Place the empty cardboard box approximately to the front center part of the heatbed.

Step 6 Multi-Tool & Single-Tool

The following instructions are divided according to your printer variant.

⬢Choose the appropriate steps:

⬢Multi-Tool: please proceed to the next step
