Desligamento automático (Automatic shutdown) Longer LK4/LK4 Pro - Alfawise U30/U30 Pro

thingiverse

In order to create a system that detects when a print is finished, and automatically turns the printer off, I developed a program for the ESP32 that can, from a button on the top of the printer, detect when the printing has finished and turn the machine off from a Sonoff smart switch. I designed a 3D model of a support for the button and ESP32, taking into consideration my printer, Longer LK4 Pro and similar models. However, I'm attaching the file in .ipt extension to anyone interested in modifying it, so that it can be adapted to their machine. The C++ program can also be modified in the same way, allowing the use of another microcontroller. Follow these steps below in "Post-Printing" to perform the installation and configuration procedure correctly. Materials needed: 1x Printed support 1x ESP32 module 1x Sonoff smart switch 1x Button key 2x Nylon clamps 1x Female jumper 1x Micro USB cable for 5V power If you liked my work, consider making a donation through the link below: https://bit.ly/2NSbKnB
