Hello,
All of the sudden, I am getting a major air leak from on top of the machine. I cannot find it as it may be in the casting. It sounds like it is coming from behind the Z axis motor. There is some air coming through the spindle in the spindle clamp and unclamp state. Any idea what this could be? It only occurs when power to machine is on, so I am assuming a valve is telling it to let air through.

Any help would be appreciated and thanks in advance.
