Neptune Maxout: Easier Klipper installs, OTA updates, custom themes, KAMP, and guided calibration

The Neptune Maxout project has received a major update! It is designed to make installing and using Klipper on the Elegoo Neptune 3 family easier—even for new Klipper users.

GitHub:

https://github.com/HDR-Performance/Neptune-3-Maxout-Configs

WHAT DOES IT DO?

Instead of manually creating folders and uploading every configuration file separately, users can select the package matching their printer and controller and install it through SSH.

SUPPORTED PRINTERS

• Neptune 3

• Neptune 3 Pro

• Neptune 3 Plus

• Neptune 3 Max

SUPPORTED HARDWARE

• Stock Robin Nano controller

• BIGTREETECH SKR 3 EZ

• Pad 7 with CB1

• Pad 7 with Raspberry Pi CM4

• Raspberry Pi 4

• BIGTREETECH Pi V1.2 and compatible 7-inch screens

NEW FEATURES

🔄 OTA updates through Mainsail

After the first SSH installation, Neptune-Maxout-Configs appears in Mainsail’s Update Manager. Future improvements can be installed without manually copying every file again.

🎨 Custom KlipperScreen experience

• Neptune Maxout theme

• Landscape and portrait layouts

• Four Pad 7 screen orientations

• Correct touchscreen mapping

• Custom controls and menu shortcuts

• Optional retro toy-laser button sounds

• Separate CB1 and CM4 handling

📐 Z Calibrate + Clean

This guided tool can home the printer, optionally heat the bed, clean and purge the nozzle, open Klipper’s TESTZ controls, and save the new Z offset.

🛏️ Guided bed tools

• Front-facing bed screw map

• Support for four to six adjustment screws

• Saved screw locations

• Manual bed tramming

• Temperature-guided full bed mesh

🗺️ KAMP support

The installer can configure adaptive bed meshing, Smart Park, and controlled purge lines.

🧵 Filament and maintenance tools

• Load and unload filament

• Color changes

• Runout recovery

• Heater safety

• PID tuning

• Input-shaper calibration

• Pressure-advance material profiles

• Maintenance counters

• Improved pause, resume, and cancel functions

⚡ Experimental speed profiles

Normal, Fast, and Ludicrous profiles are being developed for controlled testing. These change Klipper’s maximum motion limits, not the speeds commanded by the slicer. Upgraded motors are strongly recommended before testing Ludicrous mode.

AFTER INSTALLING OR UPDATING

  1. Confirm that the package matches the printer and controller.

  2. Verify the MCU connection and pin configuration.

  3. Run Z Calibrate + Clean.

  4. Verify input-shaper settings.

  5. Home the printer and perform low-speed motion tests.

  6. Keep the automatic backup until successful prints are completed.

Built and tested by HDR Performance. Community testing and feedback are welcome! Tell us which printer and controller you use and how the installation goes.

Neptune Maxout update: easy Pad 7 CB1/CM4 rotation, custom theme, audio, KAMP, and Klipper configs

I’ve been building and testing a complete set of Klipper upgrades for the Elegoo Neptune 3 printer family, and the latest Neptune Maxout update is now available.

One of the biggest additions is a standalone BIGTREETECH Pad 7 screen-rotation installer supporting both:

  • The original Pad 7 CB1
  • Pad 7 units upgraded to a Raspberry Pi CM4

It provides four selectable screen orientations, properly maps the touchscreen/digitizer in every position, and restores the selected orientation after reboot.

The rotation installer runs over SSH and does not replace your printer.cfg, KAMP installation, macros, theme, or audio configuration.

Rotation-only installation

cd ~
curl -fsSL https://raw.githubusercontent.com/HDR-Performance/Neptune-3-Maxout-Configs/main/tools/install-pad7-rotation.sh -o install-pad7-rotation.sh
chmod +x install-pad7-rotation.sh
./install-pad7-rotation.sh

The repository also includes:

  • A Neptune Maxout KlipperScreen theme with landscape and portrait artwork
  • Separate CB1 and CM4 audio handling
  • Retro toy-laser-style touchscreen sounds
  • Organized KAMP and macro configurations
  • Neptune 3, Pro, Plus, and Max packages
  • Robin Nano and SKR 3 EZ configurations
  • Easy SSH installation instructions
  • Updated Neptune 3 Max SKR 3 EZ TMC5160 settings using the quieter, printer-tested StealthChop and current configuration

Important: The upgraded Neptune 3 Max motion and driver settings are designed for the documented Maxout motor, SKR 3 EZ, and TMC5160 Pro hardware. Don’t blindly copy those settings onto stock motors or a different controller.

Repository and complete guides:

https://github.com/HDR-Performance/Neptune-3-Maxout-Configs

Currently tested:

  • All four Pad 7 CB1 screen orientations and touch mappings
  • Pad 7 CM4 rotation and touchscreen controls
  • CB1 and CM4 theme/audio installation paths
  • Neptune 3 Max with SKR 3 EZ and upgraded motors
  • Installer and configuration-package structure

This is a community project by HDR Performance and is not an official Elegoo, BIGTREETECH, Klipper, Mainsail, or KAMP release. Always back up your current configuration and confirm your controller, drivers, and motors before installing.

I rebuilt my Neptune 3 Klipper configs into one free upgrade library — Neptune 3, Pro, Plus & Max

After a lot of testing, rebuilding macros, fixing KAMP behavior, and organizing my older guides, the new HDR Performance Neptune 3 Maxout Configs repository is live!

🔗 GitHub: https://github.com/HDR-Performance/Neptune-3-Maxout-Configs

The project now covers the complete Elegoo Neptune 3 lineup:

  • Neptune 3
  • Neptune 3 Pro
  • Neptune 3 Plus
  • Neptune 3 Max
  • Stock Robin Nano controllers with BTT Pad 7
  • SKR 3 EZ conversions with TMC5160 Pro drivers

What’s included

  • Organized, model-specific Klipper configurations
  • KAMP adaptive bed meshing and smart parking
  • Controlled purge movement
  • BTT Pad 7 input-shaper setup
  • Friendly manual Z-offset calibration with nozzle cleaning
  • Filament loading, unloading, color changes, and runout recovery
  • Optional persistent bed heat soak
  • PLA, PETG, and TPU pressure-advance profiles
  • PID-tuning controls and maintenance counters
  • OrcaSlicer and Cura start/end G-code
  • SKR 3 EZ wiring and firmware instructions
  • Neptune 3 Max X/Y stepper-motor upgrade guide
  • Moonraker troubleshooting and recovery instructions

I also rebuilt the guides from my older repositories into a cleaner documentation library and corrected several confusing details involving TMC current, spreadCycle/stealthChop, SKR processor selection, bed-output limits, PB9 usage, and input-shaper calibration on bed-slinger printers.

Every ZIP contains a model-specific START_HERE.md, the complete organized configuration tree, and guided installation information.

These are community modification packages, so always verify your exact controller, MCU, wiring, probe, thermistors, heater load, and motion limits before powering up.

If you own a Neptune 3-series printer, I’d appreciate feedback, testing results, hardware variations, and feature requests. If the project helps you, consider starring the repository and sharing your build!
