After ensuring that your hot end is hot enough to print
with your current filament material, use the manual
controls in your software package to "Retract" while
pulling filament gently until it is released from filament
drive.
If switching between filament material types (e.g., PLA to
ABS), heat your extruder to the hottest printing
temperature of the two materials in order to purge the old
material and properly extrude the new material.
Cut the end of your new material so the tip is flat/round,
and feed it into the filament drive.
After placing the tip of the new material into the filament
drive, use the manual controls in your software package to
"Extrude"the filament until you can see it extruding from
the nozzle. This may require gentle downward pressure.

* If unable to feed filament properly, then try cutting the tip at
an angle before feeding it into the filament drive.
*The M2 allows you to print with many different filament
materials; however, we recommend using non-experimental
filament materials provided by MakerGear.
