FilamentDiameterSensor

ENPH 459 - Engineering Physics Project I

A Non-contact Diameter Measurement Device for 3D Printers and Filament Manufacturing

File Organization

1. Arduino - Initial prototype was implemented for Arduino.

2. Code - Includes the rest of the project's (non-MATLAB) code. Several versions of the shadow-simulator, a fork of the printer firmware Marlin(modified to interface with the filament sensor), and the sensor's firmware to be run on a STM32F3 development board.

3. Eagle - PCB layout files for the photodiode array (TSL1402CL) breakout board.

4. Matlab - Matlab script used to measure the relative print quality based on the roughness of vertical printed edges.

5. Pictures - Pictures from the sensor development and print quality testing.

6. Reference Documents - Documentation for the STM32F3 development board, the linear photodiode array used in the sensor, and the prototype sensor.

7. Solidworks - All 3D design for the sensor, mostly Solidworks with some .STL-rasterized models for 3D printing.
