Ensure again the printer is not connected to the power outlet, otherwise, there is a risk of damage to the electronics!
⬢Turn left part of the printer with the RAMBo cover towards you. Release the M3x40 screw using a 2.5mm Allen key.
⬢Open the RAMBo-cover-door and unplug ALL CABLES from the RAMBo board. Proceed carefully, unplug the connector, DO NOT PULL the cable!
⬢In case of any zip ties inside the RAMBo cover (cable management), cut and remove them.
Note there are safety pins on the some connectors (mainly motors), you need to press them before you can unplug the cables.
