Hello guys! I have my first Kickstarter project running! Please check it out and share this link!
I did a remake of my old filament sensor because there were to many parts, and it was heavy.
So this sensor detects jams in the hotend also running out of filament.
It uses a sensor and an arduino
How does it work?
- filaments spins the toothed wheel in the sensor, the sensor goes high to low and vice versa. The arduino calculates if the time between HIGH and LOW is between the programmed time, if not the arduino pin will go high and sends a signal to your buzzer
(more info in the arduino sketch)
Use dark plastic for the toothed filament roller, i noticed if you use light plastic the sensor readings where not reliable, so i covered the tooth with paint...
if the filament slips use double sided tape in the toothed roller, i made a litte notch in the roller so you can cut a piece of tape and paste it in the roller..
Did many tests with this one and it works like a charm!
3x40mm M4 bolt + nuts
1x10mm M3+ nut
4x 624zz bearings
1x velocitysensor (speedsensor arduino)
1x arduino (or attiny if you know how to program it)
- 1x Body part
- 1x Body Cap
- 1x 2020 extrusion mount (tevo tarantula)
- 2x Filament guide roller
- 1x Filament toothed roller
- 2 Part printable body
- Get rid of the 608zz bearings i Changed the holes to fit 624zz bearings instead
- Easier to install
Use no supports on the filament guide rollers!
Use supports if needed on the body parts, but i did not...
You need a well calibrated printer, and knowledge of arduino to program it (sketch is inluded)
