Fiber Maintenance Schedule
Fiber sources are sealed and don't need much. The lens, electronics, and rotary do.
Daily
- Visual lens check. Clean if you see haze or specks. Lens tissue + reagent-grade isopropyl, lift specks first with a blower.
- Wipe down work surface.
- Empty fume extractor catch tray.
Weekly
- Inspect galvo head and red-dot pointer for drift.
- Verify Z-axis backlash (move down 1 mm, then up 1 mm, should land where it started).
- Wipe down rotary if used.
Monthly
- Check fume extractor filter, replace if airflow is dropping.
- Vacuum inside the cabinet.
- Verify lens calibration with a known test pattern.
- Check all fasteners on galvo head and Z column.
Yearly
- Replace fume filter.
- Lubricate Z-axis lead screw.
- Inspect electrical connections, especially rotary plug.
Lens cleaning rules
Never wipe a dry lens with a tissue, drag a speck and you scratch the coating. Always blow first, then wet wipe with reagent IPA on lens tissue. Single direction, single pass, fresh tissue.
