Hi everyone, I'm very new to Arduino but I want to build a pickup winder, here is my problem: my project is using an A4988 stepper driver a NEMA17 stepper motor (model 17HS4023, 1,8 step angle, 12V, 0,7/phase, 4 wires); Vref screw is set to 0,48V a 10K potentiometer an Arduino uno For this proj…

Problem getting the correct speed on my NEMA17+A4489+potentiometer project
