UNPLUG
Pressing the Unplug button initiates an automated tip unplug routine. This button should be pressed if you
encounter a paused build due to the "Model filament clogged in tip" or "Support filament clogged in tip" warning
(see "Build Pause Warnings" on page
plugged tip (i.e. press the Unplug button under the Support heading to resolve a clogged support tip).
During the unplug routine the printer runs a series of purges and retries while monitoring following error.
Following error is the failure of a motor to reach its commanded position. This routine also includes a sequence
wherein the head fan is turned off for a period of time to allow the tip to heat up further. This increase in
temperature allows clogged material to liquefy further in order to eliminate the clogged tip.
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 the corresponding tip will heat to a predetermined set point temperature. Once
the tip's temperature 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.
ENABLE HEAD BUTTON
The head features two buttons, one for the model tip and one for the support tip, which can be used to purge
material from the corresponding tip or move filament away from the corresponding tip.
Figure 4-31:
Pressing the Enable Head Button button within the Tip Maintenance page makes the corresponding tip's head
button active. After pressing this button the tip will begin to heat to a predetermined set point temperature. Once
the tip reaches temperature, open the top cover and begin using the tip's head button.
• Pushing the button toward "LOAD" runs a long purge.
• Pushing the button toward "UNLOAD" moves filament away from the tip.
After the tip reaches temperature, there's a timeout of roughly 2 minutes before the tip is cooled again. The timer
is reset every time one of the head buttons is pushed or material is purged. This ensures that the tips will not be
cooled and the buttons will not be disabled unless no activity is sensed for that period of time.
