The Hall sensors are read by an Arduino Nano, which computes the angles into movement of the pantograph head and records it as G-Code. This can simply be displayed on the attached LCD display, or ...

Linear Hall-Effect Sensor According to the datasheet, SS49E is a linear hall-effect sensor that is operated by the magnetic field from a permanent magnet or an electromagnet.

The solution is to add hall effect sensors to the motor. [Robert] did all that, tested all the 36 combinations of hall effect and coil wiring, and it STILL didn’t work.
