Focus Stepper is an application and Arduino build for focus stacking with a stepper motor. This project is provided free of charge and as-is. If you enjoy this project and use it, please consider donating.
Focus Stepper requires a Java Runtime Environment to run. Make sure you have Java installed before trying to run Focus Stepper.
Windows (I have only tested on Windows 8, UI might be weird on earlier Windows versions) - https://thelostvertex.com/focusstepper/FocusStepper_win.zip

Arduino Firmware - https://thelostvertex.com/focusstepper/focusstepperfirmware.hex.zip
brew install avrdude
Once avrdude is installed, connect your arduino and you are ready to upload the firmware. On Windows make sure you have the Arduino drivers installed.
avrdude -c arduino -p atmega328p -P /path/to/USBPORT -U flash:w:/path/to/focusstepperfirmware.hex
In terminal on OS X, you can find the USB port to use by typing:
and you should find something along the lines of /dev/tty.usbmodem142121
