NOTE: The package is heavy! Always ask another person for help with handling.
⬢We're recommending a bright light above your workbench. Some parts of the printer are dark and inadequate light could make the assembly process more difficult.

⬢The package includes:
Some of the tools are intended primarily for regular printer maintenance. You won't need them for this manual. At the beginning of each assembly chapter is a list of the necessary tools.
⬢Torx T10 screwdriver
⬢2.5mm Allen key
⬢3.0mm Allen key
⬢Philips PH2 screwdriver
⬢The printer's package contains a lubricant, which is intended for maintenance. No need to apply it during the assembly. There is a dedicated online manual Regular printer maintenance.
⬢All the boxes and bags including parts for the build are labeled.
⬢The amount of parts is written on the label. This number is included in the total number of each type of part.
⬢Your package contains a letter, on the back of which is a Cheatsheet with drawings of all the necessary fasteners.
⬢The frame covers are 1:1 scale, so you can compare the size by placing the frame cover on the paper to make sure you are using the correct type.
You can download it from our site prusa.io/cheatsheet-xl. Print it at 100 %, don't rescale it, otherwise, it won't work.
IMPORTANT: The XL printer is large and it is almost impossible to have the entire body in every single picture. Throughout the manual, we will used terms to describe the side you will be working on:
⬢Front side - here are two M3nE nuts inside extrusion and a place for future xLCD screen assembly.
⬢Left side - can be recognized thanks to the safety sticker near its edge.
⬢Right side - opposite to the left side, there is no safety sticker on this side.
⬢Rear side - the remaining side, which will be used for the future PSU assembly, there is a trapezoidal printed part on each edge.
Never slide the bearing out of the rail, you may lose the bearing balls!
⬢Each motor axis has transportation protective foam pads.
⬢Take the foam pad off from both motors.
⬢Take off the bottom green linear stopper from the rail.
⬢Keep the upper green linear stoppers in the rail.
The green linear stopper will be used only during the assembly process. Once the printer is assembled, we will remove it (there is a step in the manual).
Never manipulate the printer by using the upper metal flanges. You can damage the LED lights hidden inside.
⬢During the assembly manipulate the base using the extrusions.
⬢A silicone sock is supplied with each Nextruder package.
⬢The main function of a silicone sock is to keep the temperature in the heater block stable, which improves the printer's performance.
Also, it keeps your hotend clean from filament dirt and protects it in case the print detaches from the print surface.
⬢You will be asked to install the sock later in this guide.
How to install the sock - check the article.
CAUTION: Avoid direct skin contact with the lubricant used for the linear rails in this printer. If a contact occurs, wash your hands immediately. Especially before eating, drinking, or touching your face.
⬢Lubricant accumulates in the printer's bearings, mainly in the linear rail channels.

⬢Building the XL printer is definitely a challenge. So it is important to reward yourself after the difficult parts of the manual. That's why we included a bucket of Haribo bears in the package!
After completing each chapter or challenging section of the chapter, you will be prompted to replenish energy for the following steps.
Don't eat all the bears before you start or at once! Not following instructions will have serious consequences, we are currently assembling Prusa Haribo tactical squad for this matter.
Do not eat any of the Harribo Bears now! It is VERY IMPORTANT to distribute the amount correctly during assembly. We tried all sorts of combinations of quantities. Finally, we reached a successful result.
⬢All right, eat one gummy bear. It will give you energy to start the assembly. ;) But just one!
⬢Are you ready to get started on the assembly? Let's move on to chapter 2. Base & Side frame assembly.
