The LAN module of 3DPRN printers, where present, has default network settings. The default IP address for the connection is “192.168.0.66”.
If you need to change the network parameters, the operations to follow are the following:
- Add a secondary IP address that is on network segment zero to your computer (eg 192.168.0.2, and as a gateway 192.168.0.1)
- Download putty, a software that will allow you to send commands to the LAN module via the network
- In putty, you need to initiate a connection to the default IP address of the LAN module (in most cases 192.168.0.66) brings 22
- After logging in, a command line screen will appear; when login is requested, credentials must be entered: USER: pi PASSWORD: raspberry
- Once authenticated, you need to send the command: “sudo nano /etc/network/interfaces”
- Sending this command will open a text file. If there is already a part similar to:auto eth0iface eth0 inet staticaddress 192.168.0.66netmask 255.255.255.0gateway 192.168.0.4 To change the network parameters just browse the file and write the new parameters to be set. If this part is not present, can be inserted at the end of the file. If there is a command similar to: include boot/octopi-networks.txt, then the operations described above must be performed within this file.
- To save the network parameters just press CTRL + THE
- To restart the module, you have to send the command “sudo reboot”
- Remember to delete the secondary IP on your PC once the operations are completed
However, if you are unsure about changing network settings or are not very familiar with it, you should seek the help of a systems engineer or a technician who deals with networks.
