Adjust the phase current ... First steps on a RAMPS 1.4 on a somewhat-uino (sorry Massimo). The testing-contraption to the left is a NEMA 17 stepper motor attached to an encoder.
Most stepper motors you’ll encounter in DIY projects, 3D printers, and small CNC machines are bi-polar, 2-phase ... opposite wall, about 6 meters away. The optical lever magnifies the steps ...
