Warning! The printer is heavy, two people are necessary to perform some steps in this guide. Make sure the table where the printer is being installed is close enough.


1. Unload the filament on both extruders (Utilities/Filament/Unload Filament). If you can't unload it, cut the filament and remove the spools. Also remove the spool holders. 


Note: If you are planning to send your printer to the BCN3D technical service it's not necessary to package the spools and spool holders.


2. Insert the long foam between the bottom cover and bed; move the printing surface down (Options/Maintenance/Move printing surface) until the foam is snug, to prevent vibrations during transport.



3.Remove the printing surface and place it onto the bottom foam

4. Put the bottom foam in the box and put the corner's foams. There is one corner different from the others, it is thinner to protect the printer's screen. All the corner foams have a sign to indicate their orientation. 


5. Turn the printer off and unplug it.

8. The printer's axes are blocked as a protective measure during transport. Depending on the last 4 numbers of the printer serial number, there is a different protection measure.

- Sigma D25 (S.N. larger than 0370)

Move the hotends to the sides and put the belt clamps the following way:

Note: You can print your own Belt Clamps downloading the STL file here: Printed parts (Sigma Series)

Warning: Leave 2cm between the printheads and the endstops and another 2cm between the X axis and the Y endstop.


- Sigma D25 (S.N. lower than 0371)

Move the X axis to the bottom and the both printheads to the left. Install the foams between them and the Y transition bar.



9. Cover the printer with the plastic bag and put it inside the box, adjust it with the corner foams to avoid that the packaging moves.

10. To protect the printer and reduce vibrations during transport, put the foams in the top sides above the printer until the printer fits between them



11. Put the cardboard above the printer top foams and put the packaging foam with the printing surface, the supports and the tool kits.
