Monthly 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.

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.

Lightly lubricate and clean the threaded rods. Do not use anything petroleum based. Silicone based or lithium based grease is recommended. Clean the threaded rods by running the axis up and down while wiping the threads.

Use compressed air to blow out the fan/control box while powered down.


Quarterly 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.
