Achieving the perfect cut or engraving starts with one critical step: mastering the focus function of Vertigo. Whether you are a small business owner producing custom tumblers or a maker crafting intricate wooden art, the difference between a professional finish and a wasted workpiece lies in the focal point.
In this comprehensive guide, we will walk you through the nuances of the auto focus laser engraver system and when to switch to manual mode. You will learn the exact steps to calibrate your VertiGo system for any workpiece size, ensuring your laser delivers maximum energy exactly where it counts.
Key Takeaway
- Use auto focus for standard sizes
- Switch to manual for special cases
- Always measure your workpiece first
- Secure material to avoid movement
- Clean sensors for accurate readings
- Adjust focus based on engraving or cutting
- Re-focus for every new item
1. Why Laser Focus is the Foundation of Your Business
Before we dive into the "how-to," let’s look at the "why." A focusing laser engraver works much like a magnifying glass under the sun. If the lens is too high or too low, the energy scatters.
When your VertiGo is perfectly focused:
- Engravings are sharper: No more blurry edges on small text.
- Cuts are cleaner: You can cut through thicker materials with less charring.
- Efficiency increases: You spend less time re-doing projects and more time selling them.
Understanding the balance between auto focus and manual focus is what separates a beginner from a professional operator.
2. Preparing Your Toolkit and Workspace
To get the most out of your VertiGo system, you need more than just the machine. Preparation ensures that your auto focus laser performs consistently without mechanical interference.
a. What You Need to Get Started
Before you power on the system, ensure you have the following items ready:
- Hex Key Set: For adjusting clamps and extension blocks.
- Extension Blocks: For oversized workpieces (>230 mm).
- Manual Focus Tool: The L-shaped spacer provided with your VertiGo.
- Measuring Tape: To verify the diameter of your workpiece.
- Cleaning Cloth: To keep the fixture and sensors free of debris.
b. Standard Operating Procedure (SOP) for Securing the Workpiece
A secure workpiece is a focused workpiece. If the material wobbles, your focal distance will change mid-job.
- Step 1: Clean and Inspect. Check that the fixture, clamps, and extension blocks are free of dust or resin from previous jobs.
- Step 2: Size Selection. Measure your workpiece. The VertiGo system handles a wide range, but you must set the hardware correctly first.
-
Step 3: Clamp Adjustment. * Small Workpieces (<89 mm): Remove the clamp from the fixture slide rail and move it to the first slot.
- Standard Workpieces (89 mm – 230 mm): Use the standard fixture range.
- Large Workpieces (>230 mm): You must install extension blocks. Remove the standard clamps, install the extension block onto the slide rail, and then re-attach the clamps to the blocks.
3. Using the Auto Focus Function of Vertigo
The VertiGo is designed to be a high-efficiency auto focus laser engraver. For most standard projects, this is the fastest way to get to work.
a. When to Use Auto Focus
The auto focus system is highly reliable when your workpiece diameter falls between 89 mm and 230 mm (3.5 – 9.05 inches).
b. Step-by-Step Auto Focus Operation
- Mount the Material: Secure your item in the fixture using the steps mentioned in the previous section.
- Position the Head: Move the laser head so it is directly above the highest point of your workpiece.
- Press the Button: Locate the Auto Focus button on the control panel. (Look for the target/crosshair icon).
- Wait for Calibration: The system will move the Z-axis (or F-axis) automatically. It uses a precision sensor to detect the surface and sets the optimal distance.
- Confirm Completion: Once the movement stops, the focal point is set. You do not need to press the button again unless you change the material.
c. Important Notes for Auto Focus
⚠️ Safety Warning: Always monitor the machine during auto focus. Ensure there are no protrusions on your workpiece that could strike the laser head. A collision can damage the lens housing or the drive motors.
4. Mastering Manual Focus: When and How
While the auto focus laser is convenient, a true professional knows that manual vs auto focus isn't a competition—it's about choosing the right tool for the job.
a. Why Use Manual Focus?
You should use the manual focus function when:
- The workpiece diameter is outside the 89–230 mm range.
- The surface of the material is highly reflective or transparent (which might confuse some sensors).
- You are performing a specialized deep engraving where you want the focus "dropped" slightly into the material.
b. How to Focus Laser Engraver Manually
If you need to perform an auto manual focus switch, follow these precise steps:
1 - The Spacer Tool: Take the manual focus tool (the L-shaped black acrylic or metal tool).
2 - Alignment: Insert the tool along the lower surface of the laser head. There is a protruding edge on the VertiGo head designed specifically to catch this tool.
3 - Adjustment: Using the control panel, move the workpiece along the F-axis.
4 - The "Touch" Point: Slowly move the workpiece up until the surface of the material just barely touches the bottom of the manual focus tool.
5 - Removal: Remove the tool before starting your job.

6. Pro-Tips for VertiGo Focus Success
Tip 1: The "First Slot" Rule for Small Items
Many beginners struggle with items like pens or small dowels. Remember that if your workpiece is under 89 mm, the auto focus laser sensor may not align correctly with the center of the arc.
Always move your clamps to the "first slot" on the fixture rail to provide better stability and sensor alignment.
Tip 2: Focus for Cutting vs. Engraving
- For Engraving: Focus perfectly on the surface.
- For Cutting: Some experts recommend focusing about 1/3 of the way into the material. For example, if cutting 6 mm wood, you might manually focus, then move the head 2 mm closer to the material. This puts the "waist" of the laser beam in the center of the wood.
Tip 3: Clean Your Sensors
If your auto focus laser engraver starts acting inconsistently, check the sensor on the side of the laser head.
Smoke and dust can coat the sensor, leading to incorrect readings. A quick wipe with a cotton swab and isopropyl alcohol can save you hours of frustration.
7. Summary
To summarize, mastering the focus function of Vertigo involves a simple three-step logic:
- Measure: Determine if your workpiece is within the 89-230 mm range.
- Secure: Use the correct clamp configuration or extension blocks.
- Execute: Use the Auto Focus button for speed, or the Manual Focus tool for specialized or out-of-range items.
8. FAQs
Q: Can I use auto focus on a tapered glass?
A: It is risky. The auto focus sensor works best on flat or consistently curved surfaces. For tapered items, we recommend manual focus on the specific area where the engraving will take place.
Q: What happens if I forget to remove the manual focus tool?
A: The laser head will move during the job and likely strike the tool, which could knock your project out of alignment or damage the laser head. Always double-check that the tool is removed.
Q: Does the VertiGo remember the focus from the last job?
A: The physical position remains the same, but if your next workpiece has even a 1 mm difference in diameter, your focus will be off. You should re-focus for every new material type or size.
Q: Is there an auto manual focus switch in the software?
A: Usually, the choice is made at the machine. You either press the button for auto or use the F-axis controls for manual. However, you can control Z-axis movements via software like LightBurn if your VertiGo is configured for it.
Q: Why is my laser still blurry after focusing?
A: Check your lens. If the lens is dirty or cracked, no amount of focusing will create a sharp beam. Clean your optics daily!
