How to fix error code E# on THORLABS Tools?

  Tom BeasleyAug 18, 2025
  If you're seeing error code E# on your THORLABS Tools device, it could be due to a few reasons: * Make sure the filter wheel is correctly installed, the housing is properly seated, and the thumbscrew is tightened. * Dust or debris might be blocking the sensors. Remove the housing cover and filter wheel, then use compressed air to clean any dust or debris from inside the housing and the green circuit board. * Inspect the blunt crenulated patterns on the inner rim of the wheel. If any are bent or broken, the wheel will need to be replaced.
