Dear Craig, Tweakie and Rich Thanks for the reply.
As Rich said, it is a Chinese controller( pl refer the attached .jpg image). I can move all the axis using that manual controller. Unfortunately, there is no physical movement of the axis via Mach 3. I tried to move all the axis by using jogging in the software (by using Tab function we can enable it in the software), by giving commands in Manual data input (MDI) and by running a G code program. There is no physical movement. However, the values in the software are changing.
What is the wrong?
