Powering Down
When the Power Switch is turned off the unit begins a controlled shut down. The software
processes are stopped and the power to the liquefier and chamber heaters are turned off. The
Controller Board continues to monitor the temperature of the liquefier and the fans will
continue to run. During this time the display will show
“Shutting down”
. The head blower fan
continues to run to cool the liquefier down quickly to prevent backflow of material from the
liquefier. If the material is not cooled down during power down the system may experience a
loss of extrusion due to material build up at the liquefier. Once the liquefier temperature
drops below 102
° C the SBC changes the display to
“Shut down”
and turns off.
Loading Material
When the load material button is pressed with carriers installed the SBC will ask the
Controller Board to unload the carriers requested by the operator. The most recent value for
material remaining is written to the cartridge EPROM. The material is run in reverse to
unload the liquefier. When filament is clear of the filament sensor the Controller Board tells
the SBC that the command is complete. The SBC sends
“REMOVE CARRIER”
to the display,
the carriers are unlatched, and the unit waits for you to respond.
If there are no carriers in the printer when the material button is pushed, or if an unload has
just been completed, the SBC will ask the operator to
“INSERT CARRIER”.
The unit will look
for a valid carrier EPROM. If there is no change to the EPROM status in 30 seconds, you are
asked if you want to RETRY. Once valid carriers are read, the unit begins the material load
sequence.
