It was greasy and dirty. I had to disassemble it and clean every part. The depth measuring bar was bent and was not in the middle of the carriage, also it broke off when I wanted to bend it back. Before the cleaning, it was so clogged that I couldn't move the carriage smoothly. The carriage linear rail slot is wider than the bar that goes into it so it is has too much play and it allows 4-5°misalignment, therefore it can no way provide the 0,02 mm accuracy mentioned in the description.
