I have a china cnc zone router that uses that JP-1635a board as the controller for the A axis. The A Axis is no longer working. When I boot up (power on) the machine the RED led light is showing on the JP-1635A board. Not sure what this red led is indicating. How can I troubleshoot this board to determine the nature of the problem?
Any help would be greatly appreciated.
