NWA3D A31 User Manual
f. When the printer is fully heated, you may want to remove all of the
filament color left in the printer from previous prints before you start a
new print. To do this, manually push filament through the extruder as you
squeeze the extruder release lever until the new color starts coming out
of the nozzle.
Pro Tip
:
Never leave the printer preheated with material
inside of it when it is not printing. The filament will bake
inside of the nozzle assembly and create a clog.
2. Removing filament
To remove the filament cleanly, you should do a “soft pull.” This involves
heating the nozzle to 100°C, and then pulling the filament out of the printer.
a. Select Setup > Preheat soft pull and wait until the nozzle to reach the set
temperature.
b. Wait a minute for the temperature to become stable.
c. When the nozzle temperature is a stable 100°C, squeeze the extruder
release lever and pull the filament out of the extruder with a steady, firm
motion.
d. Cut the end of the filament to remove irregular melted plastic at the end.
Pro Tip
:
Feed the end of the filament roll into the hole
on the side of the spool. This will insure it doesn’t get
tangled and cause a build to fail the next time you use it.
e. Remove the filament from the filament spool holder.
