Optical rule covers 1530 without encoders

X-axis ruler covers for the 1530 machine. This is a set of parts for upgrading the machine by installing additional protection for the X-axis rulers. It is designed for newer machines where there is no need to change the location of the rulers and encoders, so the set does not include these components. The cover signicantly reduces maintenance frequency by protecting the encoders from contaminants generated during the cutting process, such as metallic dust and residual gases. Previously, these contaminants would accumulate on the transverse position sensor, impairing accurate readings. To ensure proper functioning, weekly cleaning was required. With this new solution, cleaning is only required once every six months. This enhancement not only extends encoder lifespan but also improves cutting quality and precision
