Electronics and features
On the bottom of the printer, you can access the power supply’s cabling via four screws.
If necessary, there are four free terminal connections and the output voltage can be adjusted via a small rotary wheel.
However, the mainboard should be much more interesting, which is hidden behind five more screws and the second cover. Be a bit careful when removing the cover, so that the cable from the fan isn’t damaged. By the way, this is the only one that isn’t glued, so someone has thought about this. Besides the board, there is still a surprising amount of space in this compartment for possibly expanding tinkering projects, isn’t there?
As you can see, most of the other connectors are fixed in place with hot glue, and at least some effort has been put into the cable management. The board is called Elegoo ZNP K1 V1.0 and is, as the additional components already tell us, not just a simple Marlin Legacy board.
It is equipped with KLM8G1GETF-B041 8GB eMMC memory from Samsung, a STM32F402RCT6 ARM processor and 2x DDR3L memory type M15T4G16256A. An ARM Cortex-A53 with 4 CPU cores is also hidden under the green heat sink, which is responsible for the operating system including the web interface. Fixed TMC2209 stepper drivers round off the whole thing well.
The individually controllable illumination at the top of the frame and in the print head next to the nozzle is also practical.
You can connect via an SSH client of choice with the user “root” and password “makerbase”. The IP address can be found directly in the printer’s touchscreen under Settings > About Machine. Initially, there seemed to be problems with overheating CPUs with the first Neptune 4, but everything has been in the green at all times with my copy.
So and now please don’t be overwhelmed by the multitude of possibilities in the Fluidd dashboard. If you enter the IP address into the browser of a smartphone or computer in the same network, the whole range of features of the Klipper firmware opens up. Here you can upload print files, connect a camera, control the extruder and temperatures, and much more.
Because it would simply speak the frame I do not go into detail today, but to deal with Klipper thoroughly worthwhile. But don’t worry, this is all completely optional. You can also continue to go quite traditionally with a USB stick to the printer and make there beginner-friendly everything quite simply with the touch screen.
Correctly installed and connected, the filament sensor works reliably and very quickly. A beep then indicates that there is a problem and the 3D printer is paused. After new filament has been provided, the job can be continued.
