The Elegoo Neptune 2 is a printer that has a lot to offer most users and it’s difficult to find anything even close to competitive in the $160 price range. The Neptune 2 doesn’t include this style of probe from the factory, but the controller board offers a plug for a BLTouch sensor and the extruder gantry has two holes pre-drilled where they are typically mounted. For instance, the Monoprice Cadet uses an inductive probe to determine bed location at various points as part of the automatic leveling process, which saves time when printing. While it’s not a tremendously time-consuming task, it can still become repetitive and you may find yourself wishing for a more automated solution. The overall experience of leveling the bed is similar to the Creality Ender 3 Pro, which uses a nearly identical process. The built-in leveling process moves the extruder to various points on the bed, and allows you to use a piece of paper and the thumbscrew to adjust the height offset. The build platform uses four thumbscrews to compensate for unevenness or warp in the bed and uses an endstop switch to determine the Z zero height for homing.
The Elegoo Neptune 2 uses a manual build platform leveling process with some fairly basic automation provided by the built-in firmware.
