MAINTENANCE
PRINTER LUBRICATION
To keep the CZ-300 printer running its best condition as expected, it is highly recommended to lubricate all the moving
parts periodically. Users can put two to three small drops of sewing machine oil onto the shafts of extruder module and
print bed. The grease is also commonly used for lubrication of Z-shaft. This is a beneficial way to reduce the friction so
that the parts can be moving more smoothly and easily.
EXTRUDER MODULE CLEANING
The printing process can cause the nozzle clogging that further impacts the quality of printing outcomes. Material
clogged in the extruder can even lead to filament loading problems. It is suggested to clean the extruder module
regularly by following the steps below:
(1) Remove the filament tube 15 from the extruder.
(2) Insert the cleaning pin 18 into the feed hole, and push it down to drill the filament out from the tip.
(3) Use needle nose piers to push one (small) cleaning spring 19 through the tip hole in bottom.
Each superscript number refers to the tools kit listed in the table of accessory checklist
PRINT BED GLASS CLEANING
Always keep the print bed glass clean, there might be excess glue or left plastic from previous prints stuck to the
surface. This can cause a warped or uneven print surface that makes poor printing outcomes. It is suggested to clean
the print bed glass with the tips below :
• Wipe down the glass with isopropyl alcohol. Or
• Wash the glass with warm water and a bit mild dish detergent if necessary, then rinse thoroughly.
Always make sure that the printer is powered off and the print bed has cooled down before the
maintenance. Do not use any tools that might intentionally scratch (score) the glass surface
