The SmoothStepper is a motion control device that connects to the USB port of a computer running Windows. It accepts commands from Mach3 CNC software, and produces very high quality pulse trains that drive step & direction motors.

This little stepper motor driver board is designed for a variety uses where you need to control one stepper motor. Link it up to your computer via one of our breakout boards

This power supply is designed to work with our heavy duty CNC kit parts.

Has Over-Voltage and Over-Temperature protections
Adjustable voltage for fine tuning +-5V
Internal Fan switches on automatically with temperature
Indicator LED shows operation

Nema 34 motor with 4 wires (2 phase) and a holding torque of 1150N.cm

The DM860A is a type of two-phase hybrid stepping motor driver for one motor. The drive voltage is from 24VDC to 80VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with 57mm to 110mm outside diameter and less than 8.0A phase current.
Inputs and Outputs are opto-isolated.
Overvoltage, under voltage, overcorrect, phase short circuit protection
14 channels subdivision and automatic idle-current reduction. 8 channels output phase current setting
Holding torque when the DM860A is run under high speed is also significantly higher than other two-phase drivers, what’s more, the positioning accuracy is also higher.
It is widely used in middle and big size numerical control devices such as curving machine, CNC machine, and computer embroider machine, packing machines and so on.
Replaces the older MD882 Driver

The SmoothStepper is a motion control device that connects to a computer via an ethernet cable.
