Replacement time for the nozzle wiping pad will vary depending on the types of materials you are 3D printing
with. Several spares are included with your LulzBot Mini, and additional nozzle wiping pads are available for
purchase online at
LulzBot.com
.
Print Bed
Make sure that the hot end and print bed are completely cooled and at room temperature before beginning any
cleaning or maintenance of the print bed.
Your LulzBot Mini has a
PEI film
print surface, which helps printed objects adhere to the bed. Note that the oil
on your skin can negatively affect print adhesion. For optimal performance, lightly wipe the print bed with a dry
paper towel between prints.
If you start seeing adhesion issues and your prints are not sticking to the print bed, carefully wipe the bed with
isopropyl alcohol, which you can purchase from your local pharmacy. A light and gentle sanding with fine (2000-
3000 grit) sandpaper is also helpful, which you can purchase from your local hardware store. For some filaments
a polyvinyl alcohol (PVA) glue stick, such as Uhu brand glue stick, can also improve bed adhesion.
Tool Head Cleaning
Make sure that the hot end and print bed are completely cooled and at room temperature before beginning any
cleaning or maintenance of the tool head.
Included with your printer you will find a
dental pick
and
thin wire brush
for cleaning the hobbed bolt
component of the tool head. (The hobbed bolt is the small grooved metal part of the tool head that feeds filament
into the feed hole.)
Over time you may also experience an accumulation of filament on the nozzle and heater block. To clean up
this accumulated filament, heat the hot end up to 180°C and then carefully wipe affected areas using a clean dry
cloth.
