K2-NetBlock

A small service for K2 printers that blocks outside network connections

Install methods

You can get the project onto the printer in either of these ways:

1. Git clone (k2-improvements required)
2. Copy the release folder to the printer using Fluid, then run the install script over SSH

Option 1: Install from Git

From the printer or a connected shell:

git clone https://github.com/HurricanePrint/K2-NetBlock.git
cd K2-NetBlock
sh install.sh

Option 2: Install from a release folder via Fluid

1. Download the Latest Release and extract the folder
2. Copy the project folder or release folder to the printer using Fluid.
   • Open the "Configuration" Tab (keyboard shortcut X)
   • Click the + and select "Upload Folder"
   • Choose the K2-NetBlock folder you extracted from the release zip
3. Open an SSH session to the printer.
   • ssh root@<your-printer-ip>
   • password: creality_2024
4. Run:

cd mnt/UDISK/printer_data/config/K2-NetBlock
sh install-mdns.sh

Notes

• This will break any outside monitoring like Obico or Octoanywhere
