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.
