Regular cleaning recommendations

There is maintenance that needs to be done monthly, and then there are those cleaning recommendations that need to be done more frequently. If you check these parts frequently and clean them before each use, it will ensure quality engraving every time.

Air assist nozzle

The main function of the air-assist nozzle is to keep the lens clean to have a better engraving cut. This nozzle needs to be cleaned in order for it to keep the lens clean. You need to check the nozzle for clogs and dust. You can clean it by using a small brush or compressed air.

Laser mirrors and lens

With regular engraving and cutting the laser mirrors and lens are getting debris on it. Fine dust can influence the quality of the engraving. High quantities of debris can cause the laser lens to break as well.

You can use lens-cleaning wipes to gently clean the surface. You can also make use of a lint-free cloth with isopropyl alcohol for this purpose. Just be careful that you don’t scratch the lens and mirrors.

The exhaust system

The function of the exhaust system is to remove smoke and fumes while engraving. You need to clean it regularly by cleaning and replacing the filters. This can be a health hazard to have a faulty exhaust system on your engraver.

Laser beam maintenance

Another maintenance procedure that needs to be done regularly is to check the laser beam. It needs to be aligned regularly. When the laser beam isn’t aligned, the engraving can be uneven and novice-looking.

Read and follow the alignment guidelines that are included in the instruction book of the engraver. Each engraver has its own method that needs to be done. With the laser beam, the laser power also needs to be calibrated. This needs to be done when there is a reduction in power and quality engraving.

Inspect laser tube regularly

• The cooling system needs to be in working condition.

• Replacing the water of the water-cooled system on a regular basis.
