How have you connected your spindle with controller? Are you using our output board or only PWM signal from controller?

Can you post picture of your controller?
Maybe the spindle drive circuit was damaged. Usually is controlled with freq or PWM signal from controller.

Take some photos of the equipment inside the cabinet.

Problems with the control box seem quite common with these machines and im not able to diagnose of repair really , Is there an alternative spindle controller available ?

I suspect that controller in your control box is not our original product and therefore it is difficult to support it and give some proper advice. You intend to use the same brushed DC spindle?

You would probably need new spindle driver board.
Post some pictures of your electronic equipment.
