Monthly Maintenance Checklist

1. Verify Marking Consistency

Mark a series of test patterns at different power levels and speeds. Compare to your reference standard. If you need to increase power by more than 10% to achieve the same results, something has changed — investigate before it gets worse.

2. Water-Cooled System Maintenance (If Applicable)

• Check water level and top up with deionized water if needed (never use tap water)
• Inspect water quality — cloudy, discolored, or particle-laden water needs replacement
• Check for leaks around fittings, hoses, and the chiller unit
• Clean the chiller filter — a clogged filter reduces cooling efficiency
• Verify temperature regulation — the chiller should maintain set temperature within ±2°C

3. Back Up Software Settings and Marking Files

Software corruption or computer failure can wipe out your optimized parameter settings. Back up:

• Marking parameter files (power, speed, frequency settings for each material)
• Graphic files and logos
• Machine configuration settings
• Serial number counters

Store backups on an external drive or cloud service. Do this monthly at minimum.

4. Inspect and Lubricate Moving Parts

If your machine has a motorized Z-axis, linear rails, or other mechanical components:

• Check for smooth, unobstructed movement
• Apply manufacturer-recommended lubricant to rails and bearings
• Listen for grinding or binding — signs of wear or contamination

5. Review Operating Environment

• Temperature: Should remain between 15–30°C during operation
• Humidity: Keep between 10–70% RH; high humidity causes condensation on optics
• Dust and oil mist: Minimize airborne particles. Don’t place your laser marker near CNC machines, grinders, or other dust-producing equipment
