Configuring 3D Printer Print Servers for monitoring and control over the Internet

Notes:

This guide assumes the user:

• Is running Windows 10 
• Has a Raspberry Pi 3 they want to use as a print server 
• Has a home router connected to the Internet, blocking remote Internet access to your home network 

Access from the Internet will be properly secured:

• Non-persistent temporary access per session 
• SSL encrypted tunnel to protect your internal network 
• Zero firewall configuration required (port mapping, DMZ configuration) 

Session Restrictions with free version of Remot3.it:

• Can connect for a maximum of 30 minutes at a time 
• Can connect to up to 5 separate remote Print Servers behind firewalls 
• You must use a web browser to access the remote devices 
• You cannot permanently link to the web browser URL as it disappears after 30 minutes- you will need to login to Remot3.it and reconnect if your session times out. 

Let us begin!

11. When prompted, enter <4><enter> for custom TCP connection 
12. When prompted, enter <y><enter> to indicate this port is http traffic 
13. When prompted, enter <HTTP><enter> as protocol name 
14. When prompted, enter <3344><enter> as the desired port number 
15. When prompted, enter <Raspberry Pi Print Server><enter> as your server name (or something else descriptive. Note if using special characters, can only use space and dash. 
16. When prompted, enter <4><enter> to exit 
2. If you installed the Octoprint Image: 
1. Start putty, click on Default Settings, and Load button 
2. Click on Connect button

12. When prompted, enter <y><enter> to indicate this port is http traffic 
13. When prompted, enter <HTTP><enter> as protocol name 
14. When prompted, enter <5000><enter> as the desired port number 
15. When prompted, enter <Raspberry Pi Print Server><enter> as your server name (or something else descriptive. Note if using special characters, can only use space and dash. 
16. When prompted, enter <4><enter> to exit 

Remotely access your print server from the Internet

1. Using your web browser on your Windows PC, login to your Remot3.it account: https://www.remot3.it/web/index.html#
2. In Manage Devices tab, click on your Raspberry Pi’s Device Name (if it’s live and registered, should have a green check mark in the Status field) 
3. Click on the Raspberry Pi’s Service (Raspberry Pi Print Server) and click on the blue “Confirm” button. 
4. If you are in luck, a new browser tab will open, connecting you to your print server remotely over the Internet. Enter your username and password as if you were local to connect. Remember that sessions will time out after 30 minutes, and enjoy secure remote monitoring and control of your 3D printer!
