10.12 Flashing unsigned firmware
We take safety very seriously.
Before every release, our firmware goes through intense testing to
verify that
all safety features work properly.
If any of the sensor readings fall out of line, heating
is stopped to
prevent any possible damage to the printer and its surroundings.
We cannot verify
that these safety features are present in the community-made firmware.
Official firmware is
signed with a private key
and the printer verifies this signature before an
update.
To flash your own (or a community-made) unsigned firmware,
you’ll have to
break the
appendix on the Buddy board and move the jumper into the correct position. This also voids
your warranty on electronics.
First, pull out the power switch to access the appendix (1). Then take
a thin screwdriver and carefully break off the middle part (2) -
see the pictures in this chapter!
Also,
check the three pins above it
- there must be a
jumper on the two pins closer to the center of
the board.
It’s possible that the jumper is installed on a different set of pins - in that case,
move it
according to the picture below.
If the jumper is missing, add it before booting.
Breaking the appendix on the Buddy board is IRREVERSIBLE and VOIDS WARRANTY OF YOUR
PRINTER’S ELECTRONICS.
If you break the appendix, we disclaim responsibility for any possible
damage done to the printer and/or its surroundings (e.g. in case of a fire).
