New ESP32-Powered 3D Printing Projects for the Weekend

For hobbyists looking for a weekend project, five new 3D printing ideas incorporating the ESP32 microcontroller have been presented. These projects aim to enhance standard 3D printing setups or create entirely new devices with smart capabilities.

The ESP32 is a low-cost, low-power system on a chip that includes integrated Wi-Fi and Bluetooth, making it ideal for connected projects. The article details projects ranging from upgrading existing 3D printers with remote control and monitoring features to building entirely new devices. One example is a smart filament runout sensor that can notify the user when the filament is about to run out, preventing print failures.

Another project involves creating a web-enabled interface for controlling 3D printers, allowing users to start, stop, and monitor prints remotely via a web browser. This can be particularly useful for users who don't have direct access to their printer at all times. The projects often involve 3D printing custom enclosures for the ESP32 and associated components, as well as wiring them into the printer's existing system or as standalone units.

Other suggested projects include a temperature and humidity monitor for the print enclosure, which can be crucial for printing certain materials like ABS. Additionally, a project for a smart power outlet that can remotely switch the 3D printer on or off is featured. The article provides guidance and links to resources for each project, catering to a range of skill levels within the maker community.
