How does a computer control a stepper motor?

Want to use a computer to control a stepper motor, how to achieve it?

I actually want to control a stepper motor installed on a rotary table, I know that I need a stepper motor driver and control unit, and I want to know what type of controller can be programmed using a computer?

Answer 1

Control stepper motor needs to have a pulse generation device, because the computer can not generate pulse signals, so use the computer to control the stepper motor, there are several methods: 1, computer + USB to serial port + serial port control stepper motor drive controller + stepper motor; 2. Computer + USB to 485 + 485 control stepper motor drive controller + stepper motor; 3. Computer + USB to CAN + CAN controlled stepper motor drive controller + stepper motor; 4. Computer + USB + MCU + pulse control stepper motor driver + stepper motor.
