Octopi Guide: Part 2
In the first part of the Octopi guide we saw all the steps for installing and configuring Octopi on a Raspberry Pi and then remotely control all the functions of our 3D printers. Now we have to make our Raspberry visible from an external network. In fact now we are in a position to do all the operations while remaining connected to the network of our router (with address 192.168.xxx.xxx).
What do you have to do to be able to do the same when we are out of the house, or in the office? Starting with two pieces of theoretical money, we need to know that every time we switch on the router or restart it, our internet service provider assigns us a different address. This would force us to take note of it each time and put it in the address bar to make the connection. This would be the minimum but we must keep in mind that the router could restart when we are out or during the night. To avoid all this we must have a static IP address, for Fastweb users no problem, just request it and it is provided free of charge.
Octopi Guide: No-IP Service
For those who do not have it, however, can contact the free service No-Ip that after a few simple steps will allow us to have a static address. In the Home of No-Ip we have to start all registering through the button SIGN UP copy the form and confirm with the link in the email received (usual practice).
Now let’s log in and create a Hostname by entering in the marked field what we want to be our ip address. At this point we must check if our router supports the use of DDNS services and which ones are compatible.
You will then have to type (usually http://192.168.1.1 or http://192.168.0.1) to access the configuration panel of the router then go to the advanced settings and look for the DDNS or dynamic DNS section. Then, in the Service Provider menu (or similar item), you can check the No-IP support. From the router’s configuration panel, simply choose No-IP as the provider of the free DDNS service. Then enter the host name, user name and password chosen when registering on the No-IP site.
Let’s connect to this page and check our static ip address. The game is done now just enter in the address bar of our browser the address we have chosen and we will be linked directly to Octopi. The only thing we need to be aware of is to confirm our monthly subscription to No-ip via the email they send us to remind us.
