Squeaky Cetus

<p>My Cetus has begun making squeaking sounds, primarily when the rails move along the Z axis as well as the bed movement. Is there a recommended way to remove this noise? Do I need to add some kind of lubricant, and if so, where?</p>

<p>The linear rails have tiny holes, where you can fill in appropriate grease with a fine injection tool. You will get more information in the datasheets of the rails (just google them).</p><p>Nevertheless the rails (those with the blue cover) have to be maintained very rarely. How long do you use your printer?</p>
