Neptune 4 Pro 3D Printer!

A dream since 2015, second year of undergrad

Jul 19, 2023 - 2 minute read

I had my first print during the second year of my undergrad at NTHU. The department organized a trip to a startup workshop on campus. They had 3D printer, laser cutter, and all the maker stuff with them. I started designing phone stands in SketchUp

Saw this video from ShortCircuit at July, 2023 during my intership at Mediatek, Dan really sold this 3D printer to me 🤩 Dan at the end of the video: “God how is this so fxxking cheap I don’t get it”

First Setup

The first setup of the 3D printer and my first prints
This is my first setup of the 3D printer down in the basement in NW5 at Sep, 2023. I made a enclosure out of an Amazon cardboard box to keep the temp, magnets are used to hold the door open/close. Also bought a filament box to keep the filament dry, and can heat up the filament when printing. Since there is no WiFi, I use a RPi3 as WiFi-to-ethernet adapter to make the printer wireless.

Second Setup

There were some issues with the first setup.

  • The filament box is outside the chamber, feeding into the printer at a weird angle so the printhead has to pull harder
  • The table wobbles a lot when printing

To solve this, I got a nice cabinet on Amazon to sit my printer on, and cut a piece of wood from Home Depot to put on the cabinet as a nice top. Then I modified the filament holder to make it smaller to fit into the cardboard box. The tube and the inserts(?) are from Amazon (link), can just screw the inserts into the printed part (stl files).

Yup no new issues so far (as for 2023-12-27)
