Smoothing a 3D print
Smoothing a 3D print permet d’avoir un rendu plus propre, plus esthétique comme si la pièce était sortie d’un moule et c’est tout l’objectif. Le lissage d’une impression 3D est un sujet récurrent dans ce domaine. Nous allons voir dans cette article une méthode qui...
Controlling a CNC with laserGRBL and a CNC shield
In this tutorial, we’ll look at how to drive a CNC using laserGRBL software, an Arduino and a CNC shield. If you have a workshop or want to make things yourself, you’ll probably want to build or hack a CNC milling machine. In a previous tutorial, we saw a...
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...
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...
Tools for testing UDP communication
, With one or more devices connected to a Wifi network, it’s often useful to have tools to test the UDP communication protocol. It’s possible to communicate between different devices such as computers, Arduino, ESP32, ESP8266, using the UDP protocol. There...
Communication between two ESP32s via UDP
, The NodeMCU ESP32 is a small microcontroller with a WiFi chip. It is possible to establish communication between two ESP32s, when they use the same network. In this tutorial, we’ll look at an architecture with two NodeMCUs exchanging data via the UDP protocol....
Setting up a UDP server on Raspberry Pi
, When the Raspberry Pi is connected to the Wifi network, it can communicate with other devices on the network using the UDP protocol. This makes it possible to control the Raspberry Pi from another device or to manage other microcontrollers using UDP requests. It can...
UDP communication between Raspberry Pi and ESP32
In this tutorial, we’ll look at how to communicate between a Raspberry Pi and an ESP32 using the UDP protocol. When devices are connected to the same Wifi network, they can communicate very simply by exchanging data packets using the UDP protocol. As both the...Products
