Maintenance

Cleaning threads Changing nozzles may require

removing plastic from the brass and stainless steel

threads to ensure a good seal between the nozzle and

Pico body.

This can be accomplished with a combination of

acetone, tweezers, sharp objects (needle, toothpick,

hobby knife etc.), and/or a spiral wire brush that can be

found in any small gauge gun-cleaning kit.

For Pico inner threads: it is best to leave Pico attached

to your printer with the brass nozzle off, the heat on and

Z axis raised high. With the aid of a mirror, use tools to

clean plastic from between threads, being careful not to

scratch the inner bore of Pico.

For brass nozzle: it is best to soak the brass nozzle in

acetone for at least 24 hours. Then use a wire brush or

hobby knife to carefully scrape away soft plastic. Avoid

contact with the chamfer as this will scratch the seal

surface.

Cleaning the inner bore of Pico Wear proper safety

equipment. Conduct procedure in a well-ventilated

area. Note: Autoignition of acetone is 465°C

This process may be easier to complete while Pico is

unmounted but still electrically connected and safely

secured in a suitable open working area.

Remove any loaded filament while Pico is hot (See:

Starting a Print—Hot Loading and Hot Unloading

Filament).
