There are a few caviats that you must be aware about. The most significant one - this system is slow to tune. You can get a Nema 11 motor without gearbox. With driver microstepping you should be able to achieve the desired tuning precision.
The solution is using a custom version of ESP32 - LILYGO/TTGO, basically this is ESP32+TFT Display. The display is used to show IP address of the MagLoop Tuner so it can be accessed via browser.
