Maintaining Your 3D Printer
3.1 Overview
Little maintenance is required keep your LulzBot TAZ Workhorse 3D
printer running. Depending on your rate of use you will want to perform a
quick check of your printer every 2 to 4 weeks. The following maintenance
guidelines will keep your printer printing quality parts.
3.2 Smooth Rods
Wipe the smooth steel rods with a green scrub pad, clean cloth, or
paper towel. The linear bushings leave a solid lubricant that builds
up over time. Squeaking noises while the printer is in operation is
likely a sign that the smooth rods need to be cleaned. NOTE: Never
apply any lubricant or cleaning agent to the smooth rods as
the bushings are self-lubricating.
3.3 PEI Print Surface
The PEI print surface is the key to well-balanced part adhesion and release.
While long-lived, it will need to be replaced periodically and is considered
a consumable item. To clean the PEI print surface, wipe clean with
watered-down Isopropyl Alcohol 10:1 IPA to water ratio and a clean
cloth. If you encounter prints lifting from the PEI surface, use ne grit
sandpaper, typically 2000-2500 grit to clean the PEI print surface. We
do not recommend printing on bare glass, as it can lead to glass bed
damage or failure. Never use acetone to clean the PEI print surface as
doing so can damage the lm. You can nd our maintenance and guides

3.4 Hobbed Bolt
Filament is pulled through the extruder by a hobbed (or toothed) bolt.
After repeated use, the teeth of the hobbed bolt can become lled with
plastic. Using the dental pick from the printer kit, clean out the hobbed
bolt teeth. If an extruder jam ever occurs, remove the plastic lament
from the extruder and clean out the hobbed bolt.
