User Manual
Despite the name drill bit, you will not be using these in a drill at this point. You will only use them by hand.
1. Lower the print bed as far as it will go, center the X Carriage, and push the print bed to the back to
give yourself room to work.
2. Determine the size of the nozzle you need to clean, and select the appropriate drill bit from the list
above. If you don't know the size of your nozzle (it should be stamped in the side), measure a piece of
extruded filament with calipers to determine the nozzle diameter. If you don't have a piece of extruded
filament, or you don't have calipers, then start with the smallest bit, and work your way up to the
largest.
3. Heat the nozzle to the printing temperature of the most recently used filament. This is important, as the
nozzle will be impossible to clear if it is cold, or under heated. Double check that the nozzle is the
correct temperature
4. From this point on, you will be working with your hand in close proximity to the heated nozzle. Using
work gloves or gardening gloves (non-meltable, test it on a hot nozzle without your hand in it first) will
protect your hand and fingers in the event that you accidentally brush the nozzle while you are working
on it.
5. Hold the drill bit between your fingers, and insert up into the end of the nozzle. Alternatively, you can
grip the drill bit in a set of vice grips or other clamp, at your discretion.
