V400 3D printers are complex electromechanical system products, consisting of a very large number of sensors, electronics, actuators and mechanical components.
Wear and tear on some of these parts is inevitable with long-term use. Normal maintenance can reduce their wear and extend the life of the entire printer.
This page contains a tutorial on the maintenance and replacement of common parts.
As a user of a V400 machine, we recommend that you maintain the printer's performance through regular maintenance to ensure that the printer continues to operate consistently.
