1. The lament spool must be oriented
corectly (see below illustrations)
2. After the guide tube xation is
completed, press the left spring
presser of the extruder, put the
lament vertically into the left
lament intake from the other end of
the guide tube.
Install the top cover when printing ABS.
Remove the top cover when printing
PLA.
Fix the anti-oozing
plate by two M3x8
screws.
Make sure that the nozzle touches
the anti-oozing plate properly when
installed. The distance between the
nozzle and the plate can be adjusted
manually. After printing, scratches on
the plate surface can be visible. This is
not a failure but normal.
NOTE: Pay attention to extend the guide tube to the inside of the spool to prevent
the lament from being wrapped outside the spool.
Make sure that the two lament strands are installed in crossed position.
