V2 Auto/Manual spool winder, diameter sensor and cooler
Description
#I'm moving to Cults3D.com **files available at https://cults3d.com/en/3d-model/tool/v2-auto-manual-spool-winder-diameter-sensor-and-cooler-francescangelif** Once assembled my new FelFil extruder I began to design a cheap and affordable spool winder; I had to design a cooler for extruded filament and a digital sensor for filament diameter. It's modular, you can configure it at your needs. Only winder, winder and cooler with or without diameter sensor. You can adjust manually the winder speed, but it can be managed directly from FelFil extruder (or others) speed. With provided adapter the winder can support almost all spools around. - [measuring test](https://youtu.be/-DmC_qaGq3w) (accelerated) - [final functional test](https://youtu.be/_JpjYn3FgKo) - [AUTO mode test](https://youtu.be/-4CrEfahBMU) - [TFT test](https://youtu.be/EKV5Tw0jsNM)(sorry for quality but with my phone is very difficult taking movies of displays... The new V7 version of firmware introduces MANUAL/ AUTO running mode and a filament diameter sensor that warns out if diameter is out of tolerance. **MAN/AUTO** If you choose LCD 1602 display you'll find a toggle switch to select AUTO or MAN. If you choose TFT display you'll find two buttons on screen to select AUTO or MAN. MAN mode lets you choose speed via the potentiometer while AUTO mode takes input PWM signal from extruder to automatically adjust winding speed relying on its extrusion speed. **RATIOS** Ratios are based on Felfil's range 0-9; with other extruders I'd advice to keep their output this range, otherwise you have to modify all parameters in section "// ratios:" (good luck!). Furthermore, now the cooler fan speed is proportional to winding speed, utilizing D8 PWM output. VARSPEED_V7.ZIP contains all necessary software and libraries The whole project can be found in Tinkercad.com searching for "V2 AUTO/MANUAL spool winder". In this V2 version you'll find: - remixed filament diameter sensor (see Aknoledgments section) - remixed cooler - new spool clutch (yet to test)
