Question:

I was wondering if would guys happen to have and advice on how to do maintenance on the machine, such has cleaning the lenses, water chiller/laser tube maintenance, and axis lubrication

Quick Answer:

The Lens should be cleaned with Denatured Alcohol and/or Acetone.
The water chiller should be flushed every six months.
The linear rails (axis rails) should be kept wet with oil.
Open the exhaust hose and clean chips from the fan screen.

Complete Answer:

The lens should be cleaned on a regular basis. About once per week is the minimum. How often to clean is completely based on what material is being cut/engraved. If there is ever a fire.. Clean everything that might have been effected. The Lens should be cleaned with Denatured Alcohol and/or Acetone. Each of these chemicals will remove different fumes. The acetone will remove water spots that could be left behind from the alcohol. Use a Q-tip to apply the cleaner. DO NOT RUB. Use the Q-tip to apply the cleaner and dissolve off the fumes. Rubbing will cause scratches in the lens coating.

Clean the mirrors often.. Mirror nnearest to the laser tube is Mirror #1. Clean it every 3 months. Next mirror is at the end of the gantry. Clean this mirror #2 every 2 months. The mirror #3 is directly above the lens. It should be cleaned every month. Clean with same method as the len. We recommend to purchase the Gold-Silicon mirrors as they do not oxidize nearly as much as the Molybnium mirrors. You cannot clean the oxidization off.

The water chiller should be flushed every six months. You should also add a tiny amount of anti-fungal to prevent mold from growing inside the laser tube, hoses, water flow sensor, chiller tank..etc. Add clean water to the chiller, connected the exit hose from the laser machine to an extra bucket, ...and pump out the water. Do not let the pump run dry. If the hoses or tube have mold growing inside, then additional cleaning will be needed. You might even need to replace the hoses.

The linear rails (axis rails) should be kept wet with oil. You can use a rag to wipe up the extra oil. Do NOT run the laser with dry rails. The rail surfaces should always be wet to the touch.

check the exhaust hoses for chips of wood or other materials. I noticed that the fan tends to suck up small parts of my designs. Those small pieces get caught in the filter screen at the intake of the exhaust fan.
