K2-mDNS

A small mDNS responder for K2 printers that broadcasts a local hostname so the printer can be discovered on the network with an easy to remember address like:

• http://myprinter.local
• http://k2plus.local

For example you will be able to access Fluidd at http://k2plus.local:4408 or ssh root@k2plus.local

If you don't have router access to put your printer on a static ip, this is a perfect fix as the printer will always be accessable from a permanent address even when the internal ip changes.

Important

Windows users will need to install Bonjour

Install methods

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

1. Git clone
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-mDNS.git
cd K2-mDNS
sh install-mdns.sh

Then follow the prompt to enter a hostname. If you press Enter without typing anything, it will use the default hostname:

k2plus

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-mDNS 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-mDNS
sh install-mdns.sh

4. Enter the hostname when prompted.

Notes

• The default hostname is k2plus.
• If the printer does not show up immediately, make sure multicast is enabled on the network and the service is running.
