-Currently I am stilling waiting the red line laser shipping to me. What I achieved is using the arduino and a motor diver to control the stepper more smoothly compared with the one without the motor driver. I am looking for a stepper with  gears built-in, Or I need to build the gears myself. Also I need to build a V3 Pattern background for the camera calibration and  realize the synchronization of the David software and the stepper motor through COM port.
+Note: For the camera, In most cases, DAVID works in lowlight conditions to get a clear contrasted laser line. So the cam should be able to handle this. High light sensitivity and as little noise as possible is recommended. For the laser line, laser line should be as thin as possible –> focusable; as bright as possible; perfect straight line and a red or green laser if you use a color camera.
