1. Your Power Settings Are Too Low
This is the most common reason for shallow engraving, and it's the easiest to fix. If your power setting is too low, the laser doesn't have enough energy to burn deeply into the material.

How to Fix It:
- Increase the power percentage in your laser software. Start by increasing it in 10% increments and run a test engrave on a scrap piece of the same material.
🛒 Check out the TyvokStudio Laser Software here
- For most materials on a 10W machine like the Tyvok A1 Mini 10W , you'll want to use between 60% and 100% power for deep engraving.
🛒 Check out the Tyvok A1 Mini here
- Remember that different materials require different power settings. Harder, denser materials need more power than softer materials. For example:
👉 Learn more about How to Choose Laser Power for Different Materials here - Softwood: 50-70% power for good depth - Hardwood: 70-90% power - Stone: 80-100% power - Acrylic: 30-50% power (you don't need as much for deep engraving on acrylic)
Pro Tip:
If you're using a 5W machine like the Tyvok A1 Mini 5W, you'll generally need to use higher power settings (closer to 100%) for deep engraving compared to a 10W machine. That's just because you have less total power available. 5W can still do deep engraving—it just might need multiple passes.

2. Your Speed Is Too Fast
Even if your power is set correctly, if you're running the laser too fast, it doesn't spend enough time on each spot to burn deeply into the material. The laser just skims across the surface, leaving a shallow engraving.
🛒 Check out the TyvokStudio Laser Software here
How to Fix It:
- Slow down your engraving speed. Try reducing your speed by 50-100 mm/s and do a test.
- For deep engraving, slower is generally better. Slower speed gives the laser more time to transfer energy to the material.
🛒 Check out the TyvokStudio Laser Software here
- Example settings for 10W machine on hardwood:
-
100% power, 200 mm/s = moderate depth
-
100% power, 100 mm/s = much deeper engraving
Keep in Mind:
Slower engraving means your job takes longer. If you need both depth and speed, consider increasing power first before you decrease speed. Only slow down if you've already maxed out your power and still need more depth.
3. Your Lens Is Dirty
A dirty lens absorbs some of the laser energy before it ever reaches your material. Even a thin layer of smoke residue on the lens can significantly reduce the effective power that reaches your workpiece. This is a surprisingly common cause of reduced engraving depth that many beginners overlook.

How to Fix It:
- Clean your laser lens regularly. How often depends on how much you use your machine, but a good rule of thumb is to clean it every 10-20 hours of run time, or any time you notice your engraving getting shallower.
🛒 Check out the TyvokStudio Laser Software here
- Use a cotton swab with lens cleaning fluid or isopropyl alcohol (91% or higher works best). Gently wipe the lens in a circular motion, then use a dry cotton swab to remove any excess moisture.
- Be careful not to scratch the lens—its fragile. Don't press hard.
If you own a Tyvok A1 Mini or Tyvok P2, cleaning the lens is quick and easy. The lens is accessible, and it only takes a minute to clean it. Doing this regularly will not only keep your engraving depth consistent—it will also extend the life of your laser.

4. Your Focus Is Off
Laser engravers get the deepest, cleanest cuts when the laser is perfectly focused. If the laser is out of focus, the beam spot is larger and less intense, so it doesn't cut as deeply. Even a few millimeters of focus error can make a big difference in how deep your engraving is.
🛒 Check out the Tyvok A1 Mini here
How to Fix It:
- Check your focus. Most machines (including the Tyvok A1 Mini ) have a simple focusing tool or procedure.
🛒 Check out the Tyvok A1 Mini here
- Make sure you adjust your focus based on the thickness of your material. If you're working with a thicker material, you need to adjust the focus height accordingly.
- If you're doing multiple passes, double-check your focus after you've removed material—sometimes the surface level changes after the first pass, which can throw off your focus for subsequent passes.
Automatic Focus vs Manual Focus:
Newer machines like the Tyvok A1 Mini often have automatic focus, which makes this much easier. But even with automatic focus, it's good to double-check every once in a while, especially if you're getting unexpected shallow results.

5. You Need Multiple Passes
Sometimes, even with maximum power and minimum speed, you can't get the depth you want in a single pass. This is especially true with lower-power machines and very dense or hard materials. Instead of cranking your power to the max (which can cause more burning around the edges), multiple lighter passes often give better results.
👉 Learn more about How to Choose Laser Power for Different Materials here
How to Fix It:
- Run the same engraving multiple times instead of trying to get all the depth in one pass.
- Between each pass, blow away the smoke and debris from the engraving—this allows the next pass to be more effective.
- For example, if you're trying to get 1mm depth in hardwood with a 5W machine, it might take 2-3 passes instead of one. This takes a bit more time, but you'll get the depth you want.
Even on 10W machines like the Tyvok A1 Mini 10W, multiple passes can be useful when you want very deep engraving for things like signs or plaques.

6. Your Material Is Too Hard or Dense for Your Laser Power
Different lasers have different capabilities, and some materials are simply harder to engrave deeply than others. If you have a 5W machine and you're trying to engrave deeply into solid granite, you're going to have a hard time. 5W can do it, but it will take many passes.

How to Fix It:
- Be realistic about what your laser power can do. Here's a quick guide:
👉 Learn more about Pros and Cons of galvo laser for business here - 3.5W-5W: Can do nice visible shallow to medium engraving on most materials. Deep engraving on hard materials requires multiple passes. - 10W: Can do deeper engraving on most materials in fewer passes. Can handle harder materials like stone more easily than 5W. - 10W Galvo (like the Tyvok P2 ): Same power as 10W diode, but faster, so multiple passes are less time-consuming.

7. Your Diode Is Aging (Worn Out)
Laser diodes do wear out over time. As they get older, their output power gradually decreases. If you've had your machine for thousands of hours and you've noticed that your engraving isn't as deep as it used to be even with the same settings, your diode might be wearing out.
🛒 Check out the TyvokStudio Laser Software here
How to Fix It:
- First, rule out all the other issues on this list (dirty lens, wrong focus, wrong settings) because those are much more common.
- If your diode really is worn out, you'll need to replace it. Many machines allow you to replace just the diode instead of buying a whole new machine, which saves money.
- On entry-level machines like the Tyvok A1 Mini , the diode is designed to last thousands of hours, which is years of use for most hobbyists. So this is only likely to be an issue if you've used your machine heavily for a long time.

8. Air Assist Is Causing Cooling (Rare Issue)
If you have air assist set to a very high pressure, the air stream can actually cool the material too much, reducing how deeply the laser engraves. This isn't an issue on most machines because the air assist pressure is usually set correctly from the factory, but it's something to check if you've adjusted your air assist pressure manually.
How to Fix It:
- Try reducing your air assist pressure and see if your engraving depth improves.
- Air assist is still important for preventing smoke buildup and getting cleaner edges—you just don't need it cranked up to the maximum possible pressure for every job.
9. Your Bed Height Is Incorrect
If your material isn't sitting flat on the bed, or the bed height isn't correctly calibrated, your focus will be off even if you think you've focused correctly. This is especially true if you're working with smaller pieces or materials that aren't perfectly flat.
How to Fix It:
- Make sure your material is lying completely flat on the laser bed. If it's warped, shim it up so it's flat.

1. Always Do a Test Engrave First
Before you engrave your final piece, always do a test on a scrap piece of the same material. This lets you adjust your settings before you commit to your good piece. This is especially important if you're working with an expensive material.
2. Blow Away Debris Between Passes
When you're doing multiple passes, take a moment to blow away the smoke and charred debris from the engraving between passes. This allows the laser to work more effectively on the next pass, giving you deeper results.
