A Python-based graphical user interface for the precise control of a stepper motor via Arduino. This application provides real-time feedback and memory features for reliable, long-term positioning tasks.
- Absolute & Relative Positioning: Move the motor to a specific millimeter position or by a certain amount.
- Real-time Visual Feedback: A text display and a progress bar show the current position within the 0-50 mm range.
- Manual Position Calibration: If the physical position drifts, you can instantly recalibrate the system's coordinates without any motor movement.
- Manual EEPROM Control: Manually Save the current position to the Arduino's non-volatile memory and Load it back on demand. This prevents EEPROM wear from constant writes.
- Robust Command Queue: Rapid inputs are queued and executed sequentially, ensuring no commands are lost and the GUI remains responsive.
- Emergency Stop: Immediately halt any ongoing movement.
- Auto-Save on Computer Sleep: Automatically saves the motor's position to the device EEPROM if the PC is put to sleep, preventing loss of position.
- An Arduino UNO R3
- A stepper motor (QMOT QSH4218-51-10-049)
- A DRV8825 stepper motor driver
- A CNC Shield
- A separate 12V DC power supply for the stepper motor (variable voltage preferred)
- Arduino IDE
- Python 3.11
- Required Python libraries: [ pyserial, time, dearpygui, sys, win32api, win32con, win32gui, deque, wxpython, pyinstaller ]
- Required Arduino libraries: [ Accelstepper #huge thanks ]
- Ensure your hardware is wired correctly and the Arduino is connected to your PC via USB.
- Check the COM port for your Arduino in the Windows Device Manager or your OS equivalent.
- Open the Python script and change the port if necessary (the default is
'COM5').controller = StepperController(port='COM5')
- Run the main executable from the dist folder:
gui_control_v3.exe
