To utilize the wonders of quality Stepper Motors for your Tinkerer Projects, you will need something to drive that magical smoke into them. Stepper Motor Drivers are the regulators behind the curtain and this beefy DQ860HA Stepper Motor Driver is a powerful 2-phase hybrid stepping motor driver with up to 7.2A peak. Whether operated from a dedicated CNC Controller Board, or simply from a little microcontroller like an Arduino Board, the DQ860HA Stepper Motor Driver is the device to convert pulse signals from a controller into motor motion and achieve precise positioning for high voltage Stepper Motors.
Built to offer smooth operation with low noise and low heat, these DQ860HA Stepper Motor Drivers feature micro stepping up to 1/256th step. Although not incredibly fast, these motor drivers have an impressive precision that is ideal for the use in 3D Printers, laser cutting machines, and other automated CNC Projects. The DQ860HA Stepper Motor Driver also features the latest 32-bit digital processing technology in which its advanced control algorithms are capable of converting variable currents and frequency.
The DQ860HA Stepper Motor Driver comes with an automatic anti-overheating mechanism called a semi-flow function, in which it reduces the current of the circuit to 70% when no signals have been received for 500ms. Additionally, it is recommended to leave about 20mm of space around the unit clear, so as to ensure efficient heat dispersion and to avoid heat-related problems.
The DQ860HA has been designed to work perfectly with the NEMA17, NEMA23, NEMA34, and NEMA42 stepper motors.

DIP Pins SW1 to SW3: DIP Switch Settings Chart
Each different type of motor will have different current input requirements, which is why the SW1, SW2 and SW3 DIP switches are designed to adjust output current. When setting these, try to accommodate your motors’ requirements as closely as possible.

SW4: The quiescent current can be set by the SW4 dial switch. OFF means that the quiescent current is set to half of the dynamic current. ON means that the quiescent current is the same as the dynamic current.
DIP Pins SW5 to SW8: Microsteps Settings Chart:
Micro step resolution is set by SW5, SW6, SW7, and SW8 on the DQ860HA Stepper Motor Driver. From its 16 microsteps, this driver features up to 1/256th step. The last four DIP switches define the amount of steps that the motor must take per revolution, and essentially dictates the speed and torque as well. The following chart shows all the options available and what settings SW5, SW6, SW7, and SW8 need to be in to achieve desired revolutions-per-minute.
