Variable Speed Filament puller

thingiverse

Here is the information about the variable speed filament puller I built, which I have uploaded online for reference. The design utilizes an Arduino Pro Mini operating on 5 volts to execute the instructions received from the electronic circuit board. This device relies on a 12-volt power supply with an ampere rating of two amperes to energize all its components. For control and adjustment, I incorporated a potentiometer into the circuit. To manage the stepper motor responsible for pulling the filament, I utilized a relatively simple stepper driver that effectively manages the motor's performance in harmony with the 12-volt power supply's operational capabilities, while the Arduino Pro Mini's output is processed accordingly to deliver the optimal motion necessary.
