Installing OctoPi on Raspberry Pi
To control and monitor your 3D prints remotely, you can use OctoPi on the Raspberry Pi. With OctoPi, you can launch a 3D print remotely, monitor the temperature of the print head and print bed, and watch the print using a camera. In this tutorial, we'll look at how to...
Setting up a fixed IP address for your Raspberry Pi
For some projects, it may be necessary to configure a fixed IP address for your Raspberry Pi. This is because a dynamic IP address can be changed each time the power is switched on. A fixed IP address can come in handy when you're connecting remotely to your...
Configuring port forwarding
When you want to connect to a device outside your Wifi network, you need to set up port forwarding. Once your Raspberry Pi or ESP is connected to your Internet router, you can access it from anywhere by configuring port forwarding. N.B: For cybersecurity reasons, it...
