The "619 J Stepper" project is an open-source microcontroller board designed to drive a stepper motor in closed-loop mode, which is commonly used in applications like 3D printers or CNC machines. The primary goal of this board is to prevent step loss by integrating a feedback mechanism to correct motor position accurately.
Key Features of the Project:
Closed Loop Control:
The board is designed to drive a stepper motor in closed-loop mode, providing feedback to ensure precise control without losing steps.
Microcontroller:
The project includes a microcontroller (STM32F103C8T6) to manage motor control operations efficiently.
Motor Driver:
The project includes motor driver ICs (A4950E) to handle the currents required by stepper motors.
Connectivity:
The design includes pins for several communication and control signals necessary for stepper motor operation.
Additional Components:
Includes several passive components like resistors (e.g., R5, R7) and capacitors (e.g., C19) to support the core function of the board.
Additional components such as switches (e.g., SW1) for user input.
Oscillator:
A crystal oscillator (Y1) is included for accurate timing functionality.
Power Regulation:
Voltage regulation is managed by components like the AMS1117-3.3 to ensure the board and attached components operate reliably at the required voltages.
Design Inspiration:
The project takes inspiration from the Mechaduino board by Tropical Labs, which is a known solution for closed-loop stepper motor control.
