Monthly 3D Printer Maintenance
Check your belt tension. The belts should be tight enough that they feel tight when pressing down on the midpoint of the belt run. To tighten the belt loosen one belt anchor and pull on the belt to tighten, then secure and test. Make sure that the axis movement is smooth and without binding.
For 3D printer cleaning, wipe down the smooth rods. The bearings/bushings we use do not need to be lubricated- the IGUS bearings are self-lubricating. Wiping with a clean dry cloth is suggested.
If Z-axis movement isn’t smooth, you may want to wipe down the threaded rods with a lithium-based grease. Never use any petroleum based grease, which may compromise the plastic parts. We recommend Lucas white lithium grease NLGI #2. Apply the lithium grease both above and below the X ends on the threaded rods and wipe down the threaded rods. Use your preferred printer host software or the Graphical LCD controller to drive the Z-axis up and down to help further distribute the lubricant. Wipe off any excess with a clean cloth.
Use compressed air to blow out the fan/control box while powered down.
Quarterly 3D Printer Maintenance
Check the set screws on the stepper motor pulleys and the small gear on the extruder, tighten if necessary. Use of a mild thread locking compound is acceptable.
Examine the threaded rod couplers. On the AO-100/AO-101 make sure the clamps and set screws are secure. TAZ users should make sure the hose clamps are tight.
Verify that any frame screws are tight.
