Hey fellow makers!

Maintaining the optimal performance of your laser engraver doesn’t have to be complicated. Whether you’re brand new to the OneLaser X Series, some simple maintenance can go a long way.

I’ve been running my OneLaser XRF for over 6 months now and wanted to share what I’ve learned. These small upkeep tasks help me keep clean cuts, avoid headaches, and make sure my machine is running like a champ every time.

Here’s a breakdown of the 6 essential areas I check every month or two:

1. Why Maintenance Really Matters

Trust me! Skipping maintenance might not bite you today… but it will later. :grimacing:

Neglect can cause:

  • Poor engraving quality from misaligned beams
  • Smoke buildup that damages your optics
  • Reduced airflow = increased fire risk :fire:
  • Gantry wear = jittery movements

But with a few minutes of care, you get
:white_check_mark: Sharper cuts
:white_check_mark: Longer part lifespan
:white_check_mark: A safer workshop
:white_check_mark: More reliable results

2. Laser Alignment Check

One word: critical. This quick tape test shows if your beam is still centered across the bed.

:test_tube: Here’s the trick:

  • Stick masking tape on mirrors 2 & 3
  • Pulse the laser from all corners
  • Check if burns are centered.
    Not centered? Time for a full alignment.

:date: I check every 2–3 months. It’s a 5-min job that can save you hours of troubleshooting!

3. Optics Cleaning (Mirrors & Lens)

If your engravings are looking weak or fuzzy, your optics are probably dirty. Happens fast, especially with wood and acrylic.

:soap: What I use:

  • Rubbing alcohol or lens cleaner
  • Microfiber rag
  • Q-tips

I clean mine every 1–2 months (or more if I’m doing heavy production runs). Cleaner mirrors = stronger beam.

4. Nozzle Cleaning

A dirty nozzle messes with airflow and performance. Even worse, it can start a small fire if buildup ignites.

Here’s my method:

  • Wipe the exterior with alcohol
  • Q-tip the inside if needed
  • For gunked-up nozzles: soak in warm water + dish soap

:soap: Frequency: Monthly or when you notice residue building up.

5. Rails & Gantry Maintenance

Your machine’s motion system deserves love too! If your rails get dirty, the X/Y movement can get jerky.

How I clean mine:

  • Dry rag wipe-down
  • Alcohol if needed
  • No oil needed (at least for OneLaser’s X Series!)

:date: I do this every 1–2 months. Smooth rails = clean lines.

6. Exhaust Fan Care

This one’s easy to overlook… until smoke starts filling your room. :sweat_smile:

How I handle it:

  • Wipe the fan blades + housing
  • Use a shop vac to suck out dust
  • Check the vent hose too: clogs = danger!

:warning: A clean fan = safer workspace and longer fan life.

7. Catch Tray Cleaning

That tray under your bed fills up with scraps fast. If it’s loaded with wood bits or acrylic dust, you’re just one spark away from a flare-up.

:broom: My steps:

  • Slide it out
  • Dump the debris
  • Wipe it clean with alcohol or soapy water
    Simple, but important. I do this monthly.

BONUS: Coolant Check (XT Users)

If you’re on the XT model, don’t forget the coolant tank!

:wrench: Quick peek:

  • Open the back panel
  • Check liquid level
  • Top off if low

This keeps your laser tube from overheating, especially during long engraving jobs.

Tools You’ll Need:

  • Rubbing alcohol or lens cleaner
  • Q-tips + microfiber rag
  • Screwdriver
  • Dish soap + warm water
  • Shop vac (optional but helpful)
