It's a tidy powerhouse of a desktop 3D printer, but it still needs some TLC. Here are some Lulzbot Mini maintenance tips from Aleph Objects.
The LulzBot Mini is designed to deliver years of dependable performance. Even the most reliable machines need occasional upkeep. Use these tips to keep your LulzBot Mini in tip-top condition.
The large and small herringbone gears work together to drive the filament through the extruder and into the hot end. Keep spare large and small herringbone gears on hand for future maintenance needs.
Another integral part of your Mini’s tool head is the extruder idler. The extruder idler presses the filament against the hobbed bolt driving the filament through the extruder into the hot end. The new and improved Beefy Idler is a must-have to be prepared for anything. This new idler is featured in the new LulzBot Mini Tool Head v2.1, which also has improved cooling for the heat sink!
Great 3D prints start with a perfect first layer. The LulzBot Mini sets the height for the ideal first layer thickness through the Automatic Bed Leveling system. This process uses the tip of the hot end nozzle to complete an electrical circuit on each corner of the print surface. The LulzBot Mini keeps the nozzle clean by wiping it off at the beginning of each bed probing sequence on a specially prepared wiping pad.
Note: Do not use the metallic hobbed-bolt cleaning brush to clean the nozzle or heater block.
Every LulzBot Mini 3D printer includes a comprehensive tool kit and five dual-sided replacement wiping pads.
LulzBot 3D Printers use self-lubricating bushings on each axis to provide smooth, soft movement. These bushings do not need any additional lubricants, but do like to be clean.
Filament is driven into the hot end in the extruder by a hobbed bolt. This bolt is centered within the large 3D printed herringbone gear and uses small teeth to pull filament through the extruder. Included with each LulzBot 3D Printer is a fine metallic brush and a sharp, pointed dental pick. Use these tools to clean the hobbed bolt.
The LulzBot Mini uses a PEI sheet on the heated print surface. While this film is designed to last a very long time, it is a consumable item. Follow the PEI Print Surface: Maintenance guide to refresh and extend the life of your print surface. Replace the PEI sheet when damaged or if the film begins to lift.
Note: Extend the life of your PEI sheet by allowing the print surface to fully cool before removing prints.
