This text describes a user's experience building and customizing an open-source 3D printer. Let's break down the key points: **Project Goals:** * **Controlling Power:** The user wanted to control both low-voltage (DC) signals for specific functions, like LEDs, and the high-voltage (AC) power supply of the printer itself. * **Automatic Shutdown:** They aimed to create a system where the printer automatically shuts off when printing is complete, likely for safety and energy efficiency. * **Integrating PushBullet Notifications:** The user implemented PushBullet notifications to receive updates and snapshots of their prints on their smartphone. **Hardware Components & Modifications:** * **Relay Modules:** Two relay modules are used to control both AC power (for the main printer) and DC power (for an LED lamp). Relays provide a safe way to switch high-voltage circuits with low-voltage signals from microcontrollers. * **Printed Cover:** A custom 3D-printed cover is designed to house the relays and other components, improving aesthetics and organization. **Software & Automation:** * **GPIO Control:** The user utilizes GPIO (General Purpose Input/Output) pins on a microcontroller (likely an Arduino or Raspberry Pi) to control the relay modules. * **Scripting:** Bash scripts (`light_off.sh`) are used to automate tasks like turning off the printer's power supply and LED lights after printing is finished. * **PushBullet Integration:** A PushBullet plugin allows the user to receive notifications and print snapshots on their phone, enhancing monitoring and remote control capabilities. **Challenges & Solutions:** * **Timing Issues with PushBullet:** The initial script triggered light shutdown immediately after printing ended, resulting in snapshots before the LED lights were turned off. * The solution involved adding a 5-second delay to the `light_off.sh` script, allowing for better synchronization with PushBullet notifications. **Overall, this text provides valuable insights into:** * **Open-Source Hardware & Customization:** How individuals can modify and enhance existing hardware to meet their specific needs. * **Automation & Control:** The use of microcontrollers and scripting for automating tasks and improving printer functionality. * **Remote Monitoring & Notifications:** Integrating services like PushBullet to enable remote control and real-time updates for 3D printing projects.Relay Control OctoPrint Wanhao i3 3D模型
