Motivation     For home-build scanning probe systems in labs, SpecsGroup's Nanonis system is often considered a good solution with various working modes for piezo stage control. However, its' price may not be very friendly for some SPM systems, which do not need a sophisticated feedback PID loop. It is overkill especially for the non-feedback laser microwave impedance microscopy system in our lab. We had a LabView program developed by former students, but it lacks the rotational degree of freedom and line scan mode. Also, the UI's inconvenience has always been painful for users. In order to add more flexibility, I rebuilt a new control system for the SPM with QtCreator with Python as the backend. Functionalities     For convenience, all functionalities are embedded on the same page. Multithreading was implemented for scanning, imaging, and data saving. Many of the functionalities are following the workflow of Park AFM system.      Scan: By clicking "Scan", the con
