Typically, a 3D printer should undergo general maintenance every few months, or approximately 500 hours of print time, whichever comes first.

There is no specific rule for how often maintenance should be performed, but it's always best to periodically check the functionality of the components to ensure any issues are caught before they cause a print failure.

Caution: Before starting, it is recommended to check that the 3D printer is turned off and unplugged in order to avoid injury while evaluating the condition of its components.
