⚙️ Firmware

This setup is based on RepRap Firmware 3.6.1 for Duet hardware.

Useful resources:

• Documentation: https://docs.duet3d.com/
• Firmware repository: https://github.com/Duet3D/RepRapFirmware
• Community forum: https://forum.duet3d.com/

The firmware is configured entirely via G-code scripts located in the /sys directory on the Duet SD card.

Network settings, drivers, heaters, and machine limits are defined there.

---

🧩 Configuration Files

The files inside My_Config/ are intended to be placed into the /sys directory of the Duet SD card.

Typical files include:

• config.g
• Homing macros (homex.g, homey.g, homez.g)
• Optional probing or bed leveling macros

After configuration changes, a restart or M999 command may be required.

🛠️ OrcaSlicer

The folder My_Slicers/ contains prepared OrcaSlicer profiles.

These are tuned for:

• RepRap Firmware (RRF)
• Network printing via Duet Web Interface
• Standard G-code output (no Klipper/Marlin dialects)

Import the profiles via the profile management section in OrcaSlicer.

---

📦 Installation

1. Remove the Duet SD card.
2. Copy contents of My_Config/ into /sys.
3. Reinsert the SD card and start the printer.
4. Access the Web Interface via the printer IP.
5. Verify configuration.

📌 Notes

• Firmware updates may require adjustments to config.g.
• Perform PID tuning after hotend or heated bed modifications.
• Creating backups of the SD card before editing configuration files is strongly recommended.
