Unable to focus on mask and wafer at the same time with an align gap of 40um. Visually, you can see a large gap between the bottom of the mask and the top of the wafer( about 1 to 2 mm) Tried hard resetting the computer and hardware and cleaning all critical surfaces. Still no improvement. Need to investigate further.
