Since Espressif Systems arrived in our collective consciousness, they have expanded their range from the ESP8266 to the ESP32, and going beyond the original WROOM and WROVER modules to a range of further ESP32 products. There’s a single-core variant and one that packs a RISC-V core in place of the Tensilica one, and now they’ve …
As my Octoprint® Project extends, It’s time to give my Raspberry Pi®, that’s functioning as OctoPrint server with PSU control, a proper Enclosure. The goal is to make a casing that feels and looks like a complete product, simplifying installation and eliminating clutter. So at first I took the dimensions from the hardware that’s needed to run my OctoPrint …
Octoprint® is quickly becoming the best way to drive many types of machines. Including CNC and lasers mills that use the common 3D printer controllers. I have one 3D printer and one CNC machine. In my previous blog, I explained how to control multiple printer’s trough Octoprint. Now I will explain how to convert one …
ESPC2-02 Wi-Fi and BLE coexistence Module is a highly integrated single-chip low power 802.11bgn Wireless LAN (WLAN) network controller. It combines a RISC CPU, WLAN MAC, a 1T1R capable WLAN baseband, RF, and Bluetooth in a single chip. It also provides a bunch of configurable GPIO, which are configured as digital peripherals for different applications …
OctoPrint® is a great solution for controlling your 3D printer. However, it’s missing one key function. You can’t turn the 3D printer on and off. Now that we have setup our OctoPrint® Server for multiple printers we are going to add this hardware and software feature. Hardware I assume you already have your OctoPrint® Server …
In this post, we’ll be taking a closer look at the ESP32-S2 hardware, and more specifically, the ESP32-S2 Mini pinout. The ESP32-S2 is based on the Xtensa® single-core 32-bit LX7 microprocessor, up to 240 MHz. The ESP32-S2 pinout consists of 43 × programmable GPIO’s pins, 2 × 12-bit SAR ADCs, up to 20 channels. The …
As great as Octoprint® is, there are some limitations. Plus, while Raspberry Pi’s are cheap, they quickly add up in cost — memory cards, power supplies, enclosures, and even outlets in power strips and ports in network switches all add up. I started looking at how to run multiple Prusa printers on a single Pi …
The upload procedure for ESP32 boards is a little different from a standard Arduino procedure. Most Arduino’s will automatically reset when a new program is being uploaded, and will automatically enter programming mode. On some ESP boards you have to manually enter programming mode, and on the bare-bones modules, you even have to reset them …
Recently I received a package in my mailbox. When I looked, I was surprised to see that it was sent by my friend Johann Zita. He’s added some cool features to his great OMNIFIXO – M4.2. And I would like to share this with you. There are many things in this world that are super …
A thermocouple is a device for measuring temperature. It comprises two dissimilar metallic wires joined together to form a junction. When the junction is heated or cooled, a small voltage is generated in the electrical circuit of the thermocouple which can be measured, and this corresponds to temperature. Basics of Thermocouples A thermocouple consists of …
