For the following steps, we need a 3mm Allen key without the torque indicator.
Take the assembled torque indicator.
Pull out the plastic handle.
Pull out the 3mm Allen key from the torque indicator.
Keep the 3D printed indicator for later use.

Are you left or right-handed? The printer should be already laying on its left side from the previous chapter. If you are a left-hander rotate it carefully on the opposite right side (see the picture). We are going to attach the upper CoreXY part and tighten the screws to interconnect both parts together. The instructions are the same, choose the side which suits you better for tightening the screws.
It is recommended to place a cardboard pad under the side of the base to protect the work bench and the frame from scratch.
There's a hole in the extrusion that the pin has to fit into.
Move the rear profile insert inside each extrusion of the CoreXY to the rear side of the assembly.
Slide the remaining inserts approximately to the middle. Precise position will be addressed later.
Rotate the CoreXY on its longer side and put it near the top of the four base extrusions.
The rear profile inserts must be facing against the rear extrusions. Do not push the CoreXY all the way in until you are prompted.

Be careful while attaching the extrusions and CoreXY, avoid scratching them.
First, slide the CoreXY assembly on both rear extrusions.
Align the remaining profile inserts with both Z-axis extrusions.
Slide the CoreXY on both Z-axis extrusions.

Insert the M4x12 screws into both holes. Same way as you did with the base.
Proceed carefully with the 3mm Allen key, avoid scratching the frame.
There might be a slight gap between parts, we will address this in the next step.
Tighten the screws until you reach the metal plate, then stop! We will do the final tightening later on using the torque indicator.
Repeat this procedure on the three remaining extrusions.

Never manipulate the printer by using the upper metal flanges. You can damage the LED lights hidden inside.
Manipulate the base using the extrusions.
Rotate the base back on its feet (the Core XY is facing up).

Insert the shorter side of the 3mm Allen key into the screw securing the CoreXY assembly.
Tighten the screw till you reach the "OK" line and the 3mm Allen key is slightly bent.
Repeat this procedure on all M4x12 screws inserted into the Z-axis extrusions.

Turn the printer so that the left side is facing towards you. Use the safety sticker as a guide.
Focus on the left half of the extrusion base, where we will install the M3nEs nut:
Insert the nut all the way into the extrusion from the top. See the orientation of the spring (the metal sheet on the nut).
With your finger, turn the nut and align it with the extrusion. The springs on the nut should be facing down.
The exact position of the nut will be adjusted later on. For now, slide it approximately to the center of the extrusion.

Make sure the M3nEs nut is facing up like in the picture.
Place the Earthing-connector onto the M3nEs nut. The vertical part must be facing out from the printer.
Insert the M3x8rT screw and secure both parts together with a T10 screwdriver.
Do not tighten the screw completely, we might need to adjust the position of the Earthing-connector in the extrusion later on. 4-5 turns are enough.
Grounding the sides

Repeat the same procedure to install the Earthing-connectors to the top and side extrusions.
Start by inserting the M3nEs nuts in both vertical extrusions on the left side. Roughly 2 cm from the bottom extrusion.
Continue by inserting the M3nEs nut in the extrusions on the top side. Slide it approximately to the center of the extrusion.
Now place the Earthing connector onto the M3nEs nut. The vertical part must be facing out from the printer.
Proceed the same way with the extrusions on the right side of the frame.
The exact position of each nut will be adjusted later on.
Make sure all the connectors are facing out from the printer as in the picture.
Do not tighten the screw firmly, we might need to adjust the position of the Earthing-connector in the extrusion later on. 4-5 turns are enough.
Grounding the rear side
Grounding the rear side
Rotate the rear side of the printer towards you. Repeat the proces of inserting the M3nEs nuts, Earthing-connectors and M3x8rT screws described in the previous steps.
Insert the M3nEs nut in the vertical extrusion on the left side. Roughly 6 cm from the bottom extrusion.
Continue by inserting the M3nEs nut in the extrusion on the top side. Move it to roughly the initial one-third from left.
Make sure all the connectors are facing out from the printer as in the picture.
Do not tighten the screw firmly, we might need to adjust the position of the Earthing-connector in the extrusion later on. 4-5 turns are enough.

This step explains how to insert and lock the cover-clip. The exact position of each clip will be described in the upcoming steps.
Use any extrusion closest to you.
Hold the clip so that its longer side is aligned vertically. Then insert the cover-clip into the extrusion.
Once the clip is in the extrusion, rotate it 90 degrees. Both directions are fine, the clip is symmetrical
Now, the cover-clip is secured.
Note that due to tolerances, the clip might not hold in place. This is OK, its main purpose is withstand being pulled/pushed and it will be secure in place using a screw.

In order to be able to plug in cables, we need to open the box with electronics. Don't throw away the covers or the fasteners!
Loosen slightly all four screws on the XL Buddy box cover. No need to remove them completely. Slide the cover upwards and remove it.
Release and remove four M3x5rT screws on the upper cable cover.
Take the entire cover off.
Place both covers somewhere safe, we will put them back soon.
