Demo #1 - Motorized Filament Spooler

Описание: Demo of an essentially 3D-printed filament spoler with independent but sychronized stepper motors with the following major properties.

Easy adjustment of filament guider (not just for Bambulab 😀)
Width set by adjustable non-contact hall effect sensors
Automatic Width feedback
Configurable Guide Travel / Target Turn

Configurable Auto Stop features
Target spool - Shut-down when max turns limit reached (tranfered weight)
easily calculated as a function of desired max diameter as
Turns = ((Max spool diameter -Min Spool diameter) x Spool Width)/(2 x (Filament diameter)^2 )
as an alternative max turns may be calculated as a function of transfered weight but this require the density to be known and a small script (e.g. in matlab).

Doner spool - Filament run out sensor

Manual control of both guider and spooler
for easy setup

Separate OLED Display / control unit
Simple control/configuration by dual control buttons
Arrow keys (short press)
Esc/Enter (long press)
Separate direct Emergency Stop

Status overview of on-going spooling

Based on Rasperry PICO 2 controller and TMC2209 drivers
Ultra silent drivers
UART controlled driver parameters
RTI based stepper/monitor control
Synchronized dual master/slave stepper motors
