Connect the extruder main cable into the Loveboard.
Fix the Loveboard to the X-carriage using the M3x6 screw in the marked location.
Make sure the extruder main cable is well organized in the opening below the top smooth rod - so that no cable will get pinched later on, after we re-attach the cover.

Paso 8 Rear cover installation

Some of the cables share the same connector. Proceed carefully to plug all the cables into the correct connector!
Note that all the cables from the Nextruder on the left side of the print head must be guided through the dedicated channel in the X-carriage.  If the cables are not well organized in the channel, you will have problems with closing the print-fan door later on.
