Flashforge 3d Printer Unlocker

CrashForge - Flashforge 3d Printer Unlocker

This is a set of scripts that you can use to unlock your FlashForge 3d Printer which will allow you full access to the underlying Linux distribution. (I DO NOT ACTIVELY MAINTAIN THIS REPO.)

• If you are going to help/update/change this repo, please fork it, so I can upstream pull requests and merge your changes.

THIS HAS ONLY BEEN TESTED ON Flashforge Creator 3

It works on my printer, but proceed at your own risk.

Installation Steps:

1. Clone this repository or download these files as a .zip.

2. Format a USB stick as FAT32.

3. Unzip files (if necessary) and copy all files to the root of the USB stick.

4. Move the services you would like to activate from the /scripts/ folder into the /scripts/run folder.

   The following services can be activated right now via this script, automatically.

   • samba To install, please check out the CrashForge-samba repo located here.
   • open-sshd
   • full busybox /w netcat

   It can also change the root/ssh login password to the default, which is 12345.

5. Turn your printer completely OFF.

6. Unplug your printer, then turn the power switch ON for 15 seconds.

7. Place the usb stick into the printer's front USB port.

8. Turn OFF the power switch and plug your printer back in. Turn on your printer and wait.

   Your printer will now boot from the USB stick.

   DO NOT REMOVE THE USB STICK

   Once the printer has finished booting it will show a please wait notice on the screen.

   Once it has run all scripts it should show a completed notice on the screen.

   Power down your printer, plug in your printer to ethernet, or configure it via wifi.

   You can now access your printer via ssh if you have enabled it.

   OTHER THINGS I'VE GOTTEN WORKING BUT CONTAIN BUGS

   • Original NES Emulation
   • Home-Assistant control

   THINGS THAT NEED TO BE FIXED

   There is a binary in the root directory of the main flash. This allows to print a file directly from the filesystem. It does not work correctly. Fixing this will allow printing from other programs via a network socket, or by a cron job on the local file system. I have a feeling that the QT instance which runs the print daemon does not allow the serial port to be taken over. I'll figure out a way around this eventually, but I have not had time to mess with this in a few months.
