Remove the nozzle while Pico is hot (See: Removing

Brass Nozzle).

Clear out any remaining filament (See: Removing nozzle

and pushing filament through).

Soak cotton stem (not plastic stem) from a cotton swab

in acetone. (For 3mm Pico, some cotton may need

to be removed from the end of a cotton swab. For

1.75mm Pico, all the cotton may need to be removed

from the end of a cotton swab.)

While Pico is still at printing temperature, swab the inner

bores with soaked cotton swabs multiple times from

both openings of Pico until clean.

Troubleshooting

How to clear a jam in upper portion of Pico If a jam

occurs and no plastic is extruding, unload filament if

possible.

Turn the fan off and allow Pico to heat up 20-30

degrees above printing temperature of material (stay

within rated thermistor temperature limits).

Once heat creeps upwards (remove filament if you have

not already) cut new filament to a point and load into

Pico with aid of the extruder.

Extrude at a continuous high rate while quickly

dropping to print temperature and slowly ramping fan

up to speed.
