PURGE
Pressing the Purge button instructs the printer to perform a long purge. After pressing this button, the head will
move to the purge position and will heat to a predetermined set point temperature. Once the head reaches this
set point, material will be purged from the tip for about 10 seconds. When changing to or from colored material it
is beneficial to perform multiple purges as this will remove all material remaining within the liquefier tips and/or
tubes to ensure that color mixing doesn't occur. The Purge button is selectable (i.e. a Purge can be initiated)
when the button is solid blue, and disabled (i.e. a Purge is in process or cannot be initiated) when gray. A
notification badge will be displayed within the button if any preconditions exist preventing the purge from
occurring.
LOAD HEAD/UNLOAD HEAD
Depending on the load status of the selected head, either the Load Head or Unload Head button will be
displayed. Pressing the Load Head button instructs the printer to load material to the corresponding head; the
button will toggle to display the Unload Head button. Pressing the Unload Head button instructs the printer to
unload material from the corresponding head; the button will toggle to display the Load Head button. A
notification badge will be displayed within the button if any preconditions exist preventing the load/unload from
occurring (see "Load/Unload Errors" on page 8-210).
HEAT/COOL
Depending on the state of the printer, either the Heat or Cool button will be displayed. Pressing the Heat button
instructs the printer to heat the corresponding tip to 270°C for no longer than 2 minutes; the button will toggle to
display the Cool button. Pressing the Cool button will instruct the printer to begin cooling the corresponding tip
back to the 0 set point; the button will toggle to display the Heat button. The tip will also begin to cool
automatically if the heat option exceeds the 2 minute time allotment and the Cool button is not pressed.
