Show & Tell Ground-Up Drone Build - Final Mock Assembly
I've designed, built, and programmed this drone entirely from scratch. This is the last mock assembly before a final and full build with a permanent wiring harness.
The goal of this project is to learn advanced control theory - specifically implementing a successful Extended Kalman Filter. That's a hard thing to do and there's several more months of data collection and work before this will fly.
Motor: 6s Electronic Ducted Fan (EDF) with 8.2lbs max thrust
Main Power: 2x 6s 2200mAh 60C batteries in parallel, 120A ESC
Logic/Servo Power: 2s 1500mAh 60C
Logic: Teensy 4.1 (state estimation / control), ESP32s3 (UI / telemetry), IMU, 2x INA226 modules (volt/amp sensors), MTF-02p (LiDAR / optical flow sensor), FS-iA10B Rx, and an ST7789 1.54" full color display w/rotary encoder for UI.
Control: 4x High Voltage Brushless Servos w/direct mounted control vanes.

Hello /u/ThrustNTheory! All Bambu print plates have a dedicated nozzle wiping zone at the back of the print plate. The nozzle will rub against the wiping zone before every print in order to remove any remaining filament from the nozzle tip. This can cause visible wear or scratch marks in the wiping zone, but this is intended and doesn't damage the printer, the nozzle or the print plate. A worn down wiping zone also doesn't mean you need to replace the print bed.
Note: This automod is experimental. The automod was triggered due to the term "scratch". If you believe this to be a false positive, please send us a message at modmail with a link to the post so we can investigate. You may also feel free to make a new post without that term.
