I can't comment about the PC, or operating system you are using. I am using an older Dell model running the XP operating system. The motor controller I am using is a Gecko G540 (supports up to 4 axis's of stepper motors). I am not at all familiar with the chinese router you are referring to. But it may help you to obtain help from the user group, if you could list some of the particulars about the chinese router. (Stepper, or Servo, number of wires to each motor, voltage rating, etc.)
