FlashForge EasySSH

Enable root SSH and SFTP on your FlashForge 3D printer in under a minute

Works on the Adventurer 5M, 5M Pro, and 5X (AD5X).

---

What it does

This is a small USB-based provisioning script. When your printer boots with the USB inserted, it automatically:

• Turns on root SSH access.
• Sets up SFTP so you can drag-and-drop files to the printer.
• (AD5X only) installs a tiny boot hook so SFTP keeps working after reboots.

---

What you'll need

• A USB stick (any size), formatted as FAT32.
• A computer to copy a couple of files onto it.
• Your printer's IP address — found in the printer's network / Wi-Fi settings.

Step-by-step

1. (Optional) Change the password. Open flashforge_init.sh in a text editor and edit the ROOT_PASSWORD line near the top. The default is flashforge.

2. Copy two things to the USB stick's root folder:

• flashforge_init.sh
• one printer folder — the one that matches your printer:
  • 5m-series/ for the Adventurer 5M or 5M Pro, or
  • ad5x-series/ for the Adventurer 5X

3. Flash the printer.

1. Power the printer off.
2. Plug in the USB stick.
3. Power the printer on.
4. Wait about 30–60 seconds. The 5m series will emit a sound when the process is complete.

4. Remove the USB and reboot the printer. Done — SSH and SFTP are now enabled.
