Filament Width Sensor - TSL1402R + Arduino Mega (Work-in-progress)

thingiverse

This is a work in progress replica of Flipper's Filament Width Sensor, adapted with a TSL1402R sensor, Mega board, and large display. Check out the video at http://youtu.be/qB5h6nYoD0Q to see it in action. The design for the case draws inspiration from Flipper's design but has one key difference: its hinge. This design feature proves extremely useful when working with extruded filament that's too thick, preventing jams by allowing the sensor to be easily opened. Connections are straightforward and clearly outlined in the code, making it unnecessary to have SMD soldering tools on hand. The sensor takes readings at a rate of four times per second and doesn't smooth these readings out. As a result, this design is incredibly sensitive. When you take a close look at the trail of filament left behind, its shaggy appearance can tell you if your filament is producing perfectly uniform material or if there's anything wrong – whether it be bubbles, tiny imperfections, or something else. For anyone interested in testing out the quality of my custom-made filament samples for themselves, all I require is reimbursement for shipping. Get in touch via private message to express interest and arrange a sample. UPDATE: I've recently revised the Arduino code and uploaded an accompanying Processing sketch to aid in debugging the system.
