QPolargraph

A Qt-based instrument interface for a two-dimensional polargraph scanner. The scanner positions a payload anywhere within its scan area using two stepper motors and a GT2 timing belt driven by an Arduino microcontroller. Any Qt binding (PyQt5, PyQt6, PySide2, PySide6) is supported via qtpy.

Built on QInstrument.
