Preparation (N4 & N4 Pro Models Only: If Plus or Max skip to - Requirements for Flashing the Image):
During the setup, you'll be asked for two key details: the current for the stepper motors and the PCB version, specific to N4 and N4 Pro models only. Be aware that these two models come with various stepper motors and PCB versions. Caution: Incorrectly setting the motor current can cause irreversible damage, so verify your selections carefully.
Determining Stepper Motor Current: Choose one of these methods to determine your motor's current:
- Serial Number: Refer to the barcode on your printer. Models before July 2023 (Neptune 4) or June 2023 (Neptune 4 Pro) use 0.8A steppers; later models use 1.2A steppers.
-
Printer.cfg File: Look in the "TMC UART configuration" section of the printer.cfg file that came with your printer. The run_current for stepper_x and stepper_y will show "0.8" or "1.0 to 1.2".
-
Stepper Inscription: Check the inscription on the X/Y stepper motors. "BJ42D15-26V77" indicates 0.8A, and "BJ42D22-53V04" indicates 1.2A.
Determining the PCB Version:
When you access the eMMC, note the PCB / Main-board's version number, which will be either V1.0 or V1.1.
- Makerbase MKS EMMC-ADAPTER V2 USB 3.0 Reader For MKS EMMC Module: AliExpress
- Alternatively, a spare eMMC & eMMC > microSD adapter: AliExpress
- See the Releases section for the latest pre-configured OpenNept4une eMMC Image. Flash with balenaEtcher or dd.
- Recommended to Back-Up original eMMC beforehand.
- Run the following startup scripts with Ethernet connected (as user mks)
ssh mks@printer_ip
Password = makerbase
Connect N4P USB-C port to PC Then connect via Serial COM8 (yours will be different) set baudrate to 1500000
User: mks
Pass: makerbase
- Access Network Manager: Use the following command in the terminal to open the network manager:
sudo nmtui- Connect to Wi-Fi:
- In the network manager, navigate to
Activate a connection. - Select your Wi-Fi network and enter the necessary credentials to connect.
Remember to save your settings before exiting any configuration menus.
~/kiauh/kiauh.sh- In the Kiauh menu, select Option (2), type key (a), and press ENTER.
- Once complete quit out of Kiauh.
cd ~/OpenNept4une/ && git fetch --all && git reset --hard origin/main && git clean -fd~/OpenNept4une/OpenNept4une.sh- Perform Option (1): Install the latest OpenNept4une Printer.cfg, When prompted answer (yes) to updating other configurations (KAMP / moonraker etc).
- Once you have rebooted re-run:
~/OpenNept4une/OpenNept4une.sh- Then Perform Option (4): Update MCU & (Virtual) MCU RPi Firmware (Select All but Skip Pico for now)
Follow these steps to configure the basic settings on your Neptune 4 printer's custom Armbian image:
- Access Armbian Configuration: Open the terminal and enter the following command:
sudo armbian-config- Set Timezone:
- Navigate to
Personal. - Then select
Timezone. - Choose and set your correct timezone.
- Download the latest Official Release OrcaSlicer
- Configure Orca defaults for your machines model before import.
- Check/confirm Bambu Network Engine install
- Download the latest OrcaSlicer Profiles
- In OrcaSlicer click [File > Import > Import Configs...]
Config / Tuning Macros below (pre-configured in Fluidd BedTune/Level macros will begin after heating finishes. Do the Probe Z Offset cold):
BED_LEVEL_SCREWS_TUNE
Klipper Docs
(Rerun macro after each round of corrections)
CALIBRATE_PROBE_Z_OFFSET
(This test should be done cold. Paper Thickness Test. When you determine a value, click Accept and run a SAVE_CONFIG command after)
AUTO_FULL_BED_LEVEL
(Not required as using dynamic meshes before print, but useful
to see how level the whole bed is - Click Save Config & Restart
after)
Note:
PID_TUNE_EXTRUDER
PID_TUNE_INNER_BED
PID_TUNE_OUTER_BED (N4Pro only)
Pressure advance value will need your own data.
Input shaping values will also need your own data. (SPI ADXL345 & Mellow Fly-ADXL345 Pre Configured for tuning)
After editing configs or calibrating, save in the fluidd interface, then in fluidd select the top right menu > Host > reboot. Avoid direct power cycles; this ensures changes are saved from RAM to eMMC.
I suggest adjusting the Flow Rate by following the instructions in this link. While the other tubing techniques can be beneficial, I advise against doing pressure advance tuning and control in this context. It may be necessary to turn off firmware retraction when conducting retraction tests during the tuning process. OrcaSlicer Fine Tuning

Displaying Thumbnails on the Original Display
All Slicers that generate thumbnails that moonraker is capable of understanding should work. The display uses 160x160 pixels to display the thumbnail, so your generated thumbnails should be at least that size.
