Replacing
the Ultimainboard
For internal use only
Replacing the Ultimainboard
Important: First make sure you are working ESD safe. The
Ultimainboard is very vulnerable to ESD events. There is a high chance
that the Olimex will be damaged if this repair is not done in an ESD
safe way.
Important: Make sure the filament is removed, the Ultimaker is
turned off and the power supply is disconnected before you start the
replacement.
Tip: All orientations are noted as seen from the front of the printer
Note: These instructions are the same for the Ultimaker 3 and
Ultimaker 3 Extended.
