This text appears to be a detailed guide on setting up a 3D printer, specifically focusing on the wiring and components involved. Here's a breakdown of the key points: **1. Wiring and Components:** * **Relays:** Two relays are used: * A 30A relay controls the main power to the SKR board (the printer's control system), allowing it to be switched on/off manually or via the Raspberry Pi (RPI). It can also be directly powered as an override. * A dual-channel 10A relay is used to control LED strips and has a spare channel for future use. * **DC-DC Converters:** Three DC-DC converters provide power: * One converts the mains voltage to 5V, powering the RPI and relays. This method avoids putting stress on the RPI's 3.3V GPIO pins. * Another powers a Noctua case fan connected to the 30A relay, ensuring it runs when the printer is on. * The third powers a thermal fan directly from the SKR board, controlled by firmware settings and activated at 50°C. **2. Switches:** * Two switches are currently used: * One allows manual switching of power to the 30A relay, bypassing the RPI and enabling direct power on/off. * Another provides an emergency shutdown option, breaking the circuit to the 30A relay. * The user plans to replace these with a three-position switch for combined functionality, including manual control of the LED strips. **3. Additional Tips:** * Use anti-slip pads on the bottom of the printer case for stability. Battery silicone pads are recommended over standard foam ones. * Connect the Raspberry Pi to the SKR using jumper wires instead of a USB cable, keeping all wiring inside the case. * Avoid cutting up old mattresses indoors as they release dust and fibers that will accumulate on electronic components. **Overall, this text provides valuable insights into a particular 3D printer setup, highlighting the chosen components, their functions, and some practical tips for optimizing the build.**Endecker 3外置电子箱V2
