Ideal for linear motion with Nema 17 stepper motors, such as 3D printers, laser cutters and engravers.
Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step. Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay). Over-temperature, thermal shutdown, under-voltage lockout, and crossover-current protection.
Warning: connecting or disconnecting a stepper motor while the driver is powered can destroy the driver.
