The tiny screws connecting the Mosquito™ Heat Sink to the Mosquito™ Hot Block are loose. What should I do?
Those screws are M1.4x0.3, length 10, and are assembled with red thread locker. The thread locker can lose it's effectiveness if the hotend is disassembled and reassembled. Please remove the screws, wipe off the old thread locker, and apply a new coat. The screws should be retightened to 0.12 Nm of torque.
