Ender-3 DuetWiFi enclosure

thingiverse

This is my take on the DuetWiFi enclosure for the Ender 3. It's designed to be a retrofit instead of using the stock electronics enclosure. You may need to extend your wires in order to use it without limiting your maximum print height. This is an extremely early, pre-alpha design. If you encounter any issues or have questions - please let me know, and I'll be glad to resolve them. You can reuse your stock 40x10 cooling fan from the Ender 3. Make sure to install it before placing in your board because otherwise, you won't be able to reach two bottom screws. Use M3 screws to secure the board in place. MAKE SURE TO WIRES ENSTOPS CORRECTLY OR YOU WILL DAMAGE THE BOARD!!! The standoffs for the board are intentionally made tall. Based on Duet's official cooling guidelines, the board has to be cooled from the bottom, so I had to raise it to encourage airflow underneath. If you like noise, you can connect your board cooling fan to any of the "Always On Fan" connectors and enjoy it as much as you want. If you are like me and don't like noise, then: 1. Calibrate Duet's internal MCU temperature sensor so that it reads accurately: https://duet3d.dozuki.com/Wiki/Calibrating_the_CPU_temperature 2. Connect the electronics cooling fan to the "PWM FAN2" connector 3. Use the following command in your config.g file: M106 P2 L0.5 X1.0 T30:50 H100:101:102 This will make your fan start only when it's needed. Make sure to properly set parameters for your thermistor. Google them or use the manufacturer's official guidelines. Otherwise, your temperature readings may be way off. Steps/mm for Ender 3: I deleted my steps/mm for extruder since I use a geared Titan instead of stock. The stock extruder is roughly 93 steps/mm. Try it as a starting point and then just run your normal calibration routine: M350 X16 Y16 Z16 E16 I1 ; Configure microstepping with interpolation M92 X80 Y80 Z400 E93 ; Set steps per mm Motor currents (based on stock Ender-3 setup): M906 X750 Y750 Z750 E900 I50 ; Set motor currents (mA) and motor idle factor in percent M84 S30 ; Set idle timeout Hope this helps.
