To grease or not to grease.

You may not find it written anywhere on the laser or any instruction manual that comes with it but you need to reapply grease on a monthly basis in order to make sure your machine is running at it's best. I personally use a variety including three and one, lithium grease, and de ruster and grease. It is a tool with many moving parts so just like anything else with moving parts make sure you're paying attention to the state of your machine. If your laser cutter is starting to get rust it means you're not cleaning and greasing the machine regularly enough.
