¶ Master Maintenance and Care
Maintain the optics, enclosure, and water system on schedule to preserve laser power and processing quality.
¶ Master Maintenance Schedule and Service Frequency Table.
¶ Cleaning the Reflective Mirrors of Master
Please refer to the cleaning tutorial video of reflective mirror and focusing lens of Master.
Note
- Risks of not cleaning the mirrors:
Dirty reflective mirrors can reduce the CO₂ laser power and may also cause laser energy to concentrate on the mirror surface, potentially damaging the mirrors.
- Cleaning tools:
Lint-free cloth + anhydrous ethanol.
- Cleaning method:
- Cleaning Mirror #1:
First open the laser tube protective cover, then quickly remove the Mirror #1 holder tray. Use a lint-free cloth dampened with anhydrous ethanol to gently wipe the mirror surface.
Note: Wipe in a single direction only (for example, in a spiral motion from the center outward) to avoid scratches caused by back-and-forth rubbing.
- Cleaning Mirror #2:
Quickly remove the Mirror #2 holder tray directly, then use a lint-free cloth dampened with anhydrous ethanol to gently wipe the mirror surface.
Note: Wipe in a single direction only (for example, in a spiral motion from the center outward) to avoid scratches caused by back-and-forth rubbing.
- Cleaning Mirror #3:
First remove the magnetic protective cover, then quickly remove the Mirror #3 holder tray. Use a lint-free cloth dampened with anhydrous ethanol to gently wipe the mirror surface.
Note: Wipe in a single direction only (for example, in a spiral motion from the center outward) to avoid scratches caused by back-and-forth rubbing.
- Cleaning result inspection:
After cleaning, inspect the mirror surface under strong side lighting to ensure that no water stains or fibers remain.
- Recommended cleaning frequency:
For high-frequency users:
-
Mirror #1: once every 2 weeks
-
Mirror #2: once per week
-
Mirror #3: once per day
- Precautions:
Do not use ordinary cotton cloth or gauze for cleaning, as they may leave water stains or lint residue. The cleaning agent must be non-corrosive.
¶ Cleaning the Focusing Lens of Master
Please refer to the video on cleaning the Master reflector and focusing lens .
Note
- Risks of not cleaning the lens:
A dirty focusing lens can reduce the CO₂ laser power and may also cause laser energy to concentrate on the lens surface, potentially damaging the focusing lens.
- Recommended cleaning tools:
Use a lint-free cloth or optical-grade lint-free cotton swabs for cleaning (avoid ordinary cotton swabs that may shed fibers).
Use 99% anhydrous ethanol or a professional optical lens cleaner (avoid solvents containing ammonia or acetone).
- Cleaning method:
Use a lint-free cloth dampened with 99% anhydrous ethanol or a professional optical lens cleaner (avoid solvents containing ammonia or acetone) to wipe the lens surface.
Wipe in a single direction only (for example, in a spiral motion from the center outward) to avoid scratches caused by back-and-forth rubbing.
- Cleaning result inspection:
After cleaning, inspect the lens surface under strong side lighting to ensure that no water stains or fibers remain.
- Recommended cleaning frequency:
Clean once every 3 hours of operation.
- Precautions:
Do not use ordinary cotton cloth or gauze for cleaning, as they may leave water stains or lint residue. The cleaning agent must be non-corrosive, otherwise the focusing lens may be damaged directly.
When cleaning the focusing lens, also check whether the air outlet of the airflow shield/nozzle is clean. If dirt or residue is present, clean it promptly.
¶ Cleaning the Master Enclosure
Please refer to the Master enclosure cleaning tutorial video.
Note
- X/Y Rail Cleaning:
Use a lint-free cloth dampened with anhydrous ethanol to gently wipe away dirt, dust, and debris from the X/Y rails.
Recommended cleaning frequency:
-
High-frequency users: once per week
-
Low-frequency users: once every two weeks
- Machine Frame Cleaning:
Use a lint-free cloth dampened with anhydrous ethanol to gently wipe dirt and dust from the machine frame, outer housing, and interior surfaces.
Recommended cleaning frequency:
-
High-frequency users: once every two weeks
-
Low-frequency users: once per month
- Fan Cleaning:
Use a lint-free cloth dampened with anhydrous ethanol to gently wipe dirt and dust from the fans.
Note: The exhaust fan may accumulate oily residue, so make sure it is cleaned thoroughly.
Recommended cleaning frequency:
-
High-frequency users: once every two weeks
-
Low-frequency users: once per month
- Precautions:
-
Avoid using cleaning agents that contain ammonia, acetone, or similar solvents.
-
Do not apply excessive force while wiping, as this may cause scratches or damage.
-
Keep the machine operating environment dry. Long-term operation in humid environments is not recommended.
¶ What Happens If the Water Tank of Master Is Not Replaced for a Long Time?
-
It can lead to scale buildup inside the water circulation system.
-
It can reduce cooling efficiency.
-
In severe cases, it may damage the CO₂ laser tube.
¶ How to Determine Whether the Reflective Mirrors or Focusing Lens of Master Need Replacement
-
If the surface shows signs of burning, yellowing, or stains that cannot be cleaned off.
-
If the cutting performance has noticeably weakened.
¶ Precautions for Long-Term Inactivity of the Master
If the engraving machine will not be used for an extended period, store it in a dry environment. It is recommended to power on and run the machine for 5 minutes once a month to help maintain the lifespan of the electronic components.
