Clem likes working with metal, but it takes longer to set up the bender and clamp the workpiece than actually doing productive work with it. And it is usually much bigger than it needs to be! Just having it automatically clamp the workpiece would make things a lot faster! So Clem builds a semi-automatic machine that knows when it has correctly clamped the workpiece! He uses a Trinamic TMC2130 stepper driver and an Arduino Nano and explains sensorless homing on the way!
