ELEGOO Neptune 4, Neptune 4 Plus, Neptune 4 Max X Axis Linear Rail Upgrade Installation Guide

TBStron3D provides you with the simplest upgrade solution and the most comprehensive installation guide. Upgrade operation steps. 1.In the event of a power outage, disconnect the nozzle connection cable and the auxiliary fan connection cable. 2.Loosen the timing belt adjuster. 3.Remove the auxiliary fan assembly. 4.Remove both ends of the timing belt from the X-axis backplate. 5.Remove the four POM wheels on the X-axis. Alternatively, if there are two POM wheels with eccentric isolation pillars, adjust them to the loosest state (the state with the most wobbling) and remove only the top two POM wheels. 6.Remove the two M4 screws on the X-axis, then use these two screws to secure the X-beam. 7.Use M3*6 screws to secure the linear guide to the X-beam. 8.Use M3*5 screws to secure the X bracket to the slider. 9.Use M5*6 screws to secure the nozzle assembly to the X bracket. 10.Secure both ends of the timing belt to the X-axis backplate. 11.Use M4 screws (M4*35 for Neptune 4, M4*40 for Neptune 4 Plus and MAX) to secure the auxiliary fan assembly to the X-beam.
