Neptune 4 TL4970 and Neptune 4 Pro TL4972 - Elegoo 3D Printer support EAU

Owning a 3D printer is a bit like owning a race car - you are the mechanic as well as the driver, so you'll need to do some maintenance, and occasionally fix things when they go wrong. You'll need to own a PC, have an internet connection, know how to use screwdrivers and spanners, and have the confidence to pull things apart for maintenance and repair.

Elegoo have an excellent collection of support resources to assist you in replacing parts yourself.

Note that some components such as build plates, nozzles, heaters and thermistors are consumables that wear as you use them (just like tyres on cars), and are expected to be replaced by the owner when worn out. Hot ends have a 3 month warranty, extruders have a 6-month warranty, and the printer base structure has a 12 month warranty.

These two printers share the same basic components. The differences between them are:

• Neptune 4 Pro has an 'all metal dual-axis guide rails' and 'double-row ball U-shaped bearing' on the X and Y axis'. The non-Pro has POM V-guide rails.
• The Neptune Pro has a segmented heated zones (one section at 100w and the other at 150w). This allows for smarter and quicker heating of the print surface in some scenarios. The non-pro has a single 250w heating element below the build plate.
