Ender-3 DuetWiFi enclosure

thingiverse

This is my take on DuetWiFi enclosure for Ender 3. Designed to retrofit instead of stock electronics enclosure. You might need to elongate your stock wires in order to use it without limiting your maximum print height. This is a super early, pre-alfa design. If you have any issues or questions - do let me know, will be glad to fix it. You can re-use your stock 40x10 cooling fan from Ender 3. Make sure to install it before you pop in your board, because otherwise you wont be able to reach two bottom screws. Use M3 screws to secure the board in place. MAKE SURE TO WIRE ENSTOPS CORRECTLY OR YOU WILL DAMAGE THE BOARD!!!!! Standoffs for the board are intentionally made so tall. Based on Duet's oficial cooling guidelines, board has to be colled from the bottom, so I had to raise it to encourage the airflow on the underside. If you like noise, you can connect your board cooling fan to any of the "Always On Fan" connectors and enjo it is as much as you wish. If you are like me and don't the noize, then: 1. Calibrate Duet's internal MCU temp sensor, so it reads accurately: https://duet3d.dozuki.com/Wiki/Calibrating_the_CPU_temperature 2. Connect electronics cooling fan to "PWM FAN2" connector 3. USe following command in your config.g file: M106 P2 L0.5 X1.0 T30:50 H100:101:102 this will make your fan to start only when its needed. Make sure to properly set parameters for your thermistor. Google them or use manufacturers oficial guidelines. Otherwise your temp readings may be waaaaaaaaay of. Steps/mm for Ender 3. I deleted my steps/mm for extruder since I use a geared Titan instead of stock, I believe stock extruder is somewhat 93 steps/mm. Try it as 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 per cent M84 S30 ; Set idle timeout Hope this helps. Cheers!
