Digital 4-axis CNC      


  It's a real digital CNC because True digital motors are used. Stepping motor is the real digital motor. I have spent a lot of time to finish my CNC project.  My machine has a 4-axis controller and 4 high torque stepping motors(NEMA#23). To make a perfect CNC at a reasonable price, Stepping motor is employed instead of a servo motor.  Stepping motor, it gives no delay time on positioning,  a simple hardware and a low price.  It generates high torque even though it's a small size.... SLA7026 is used for driving the motor.  Eventually, the controller is very compact without losing the precision.  Windows based CNC software will be ..... I am making......wait, please.  If you are interested in Power-CNC, email me.
