Section 2: Possible Causes

  1. Small bubbles in the coolant board
  1. Unvalidated third-party resin

Section 3: Diagnostic Steps

  1. Check if there are small bubbles on the coolant board.
    1. Remove the resin tank and build platform
    2. Go to touch screen to perform an 15 seconds exposure cleaning
