Short answer
ELEGOO lists its Neptune 4-series hardened steel and brass nozzle kits for both versions (ribbon-cable and Type-C) of the Neptune 4 Plus and 4 Max. ELEGOO gives the 4 Plus a 320 x 320 x 385 mm build volume, Klipper firmware and a dual-gear direct extruder with a 5.2:1 reduction. We could not confirm the manual's bed-tramming method or electrical ratings.

Watch out for
- The 4 Plus print volume (320 x 320 x 385 mm) and the 330 x 330 mm PEI platform are different figures. Size parts to the print volume.
- Both versions of the 4 Plus and 4 Max take ELEGOO's Neptune 4-series nozzle kits, but the Neptune 4 and 4 Pro need the Type-C version. Do not pass that rule on to a 4 or 4 Pro owner.

Hotend
Micro Swiss FlowTech hotend for ELEGOO Neptune 4 Plus / 4 Max (M3108)Choose the Neptune 4 Plus / 4 Max version (M3108), not the 4 / 4 Pro version (M3107).
Micro Swiss names the Neptune 4 Plus and 4 Max and says no firmware change is needed.
The Neptune 4 Max shares the nozzle-kit fit for both versions. The build volume, extruder ratio and voltage row on this page are ELEGOO's Neptune 4 Plus figures; we did not confirm them for the Max.
Questions
Do ELEGOO's nozzle kits fit both Neptune 4 Plus versions?
Yes. ELEGOO lists its Neptune 4-series hardened steel and brass nozzle kits for both the ribbon-cable and Type-C versions of the 4 Plus and 4 Max.[2][3]
What is the Neptune 4 Plus build volume?
ELEGOO lists 320 x 320 x 385 mm. It lists the PEI printing platform separately as 330 x 330 mm, so the plate is larger than the printable area.[1]
How do I tram the Neptune 4 Plus bed by hand?
We could not read ELEGOO's Neptune 4 Plus manual, so we do not describe its tramming method. Follow the manual that came with your printer.
