When embarking on a new endeavor, it’s common to have misconceptions that need clarification. I experienced this when I first got my hands on a budget-friendly laser cutter. Achieving precision is vital when cutting or engraving, similar to how slight inaccuracies can stand out when hanging a picture.
Unlike high-end commercial laser cutters that come with fixed position cameras for calibration, more affordable models may lack this feature. However, it’s still possible to achieve accurate alignment. For example, my basic Ourtur Laser Master 3 model, which doesn’t have a camera, can still deliver good results with the right approach.
Having experimented with various laser cutters, including the camera-less XTool S1, I’ve discovered different effective methods for positioning workpieces. Sometimes, traditional manual alignment methods can be just as reliable as newer technologies in specific situations.
Humble Beginnings
My laser journey began with a Laser Master 2 that didn’t have convenient features like automatic focusing or positioning assistance. I initially tried using a grid on a spoil board to lay out designs but soon realized its limitations.
Using grids can be tricky because the board needs to be securely fixed to prevent any misalignment due to movement. Additionally, ensuring the workpiece is perfectly square with the frame is crucial to avoid inaccuracies during cutting or engraving.
A Better Plan
After facing several challenges, I discovered a more effective method using wrapping paper. Wrapping paper, which is affordable and easily accessible, serves as a convenient surface for accurately aligning workpieces without the need for complex setups.
For instance, when engraving a notebook, you can create an outline on the paper, position the book within the outline, adjust the laser focus, and proceed with the engraving process. This simple yet effective technique eliminates the need for complicated alignment procedures.
The Laser Master 3 introduced a useful feature with a hinged stick for easy focus adjustment, simplifying the setup process.
No Camera, No Problem
Despite lacking a camera, the S1 offers precise control with closed-loop motor systems. With features like a laser pointer cross and motor feedback, the machine ensures accurate positioning without relying on visual aids.
For engraving tasks, the software guides users through marking the workpiece to ensure precise alignment without needing a camera. Moreover, the machine’s autofocus mechanism enhances accuracy by efficiently measuring surface distances.
But A Picture is Worth
While the S1 can capture workspace images using target decals, this feature may be more cumbersome compared to traditional alignment methods. The device includes sticky target decals, such as bullseyes and dots, for visual guidance during the setup process.
When setting up the phone app, you establish a connection to the printer and calibrate the dots following the marking routine. By aiming at each target and pressing the button, the software learns the exact location of each bullseye.
The subsequent step involves capturing a photo of the bed with your phone. With knowledge of the bullseyes being circles and their locations, the software reconstructs an accurate view of the bed. Initially transferring it to your computer involves scanning a QR code to establish a connection, but afterward, it transfers smoothly. However, it’s important to note that the shot isn’t live, meaning you need to set up the bed as desired, take the picture, and then avoid further adjustments.
One crucial tip is to avoid cutting anything on top of the bullseyes to prevent them from darkening and needing replacements – a mistake that we definitely haven’t made!
The Solution
It might seem surprising that cameras haven’t completely taken over given their effectiveness and convenient live view feature. Nevertheless, alternative methods like the Xtool system exist, which although ingenious, doesn’t address misalignment issues. However, it surpasses the wrapping paper approach for projects with unknown sizes.
If you know the dimensions of the workpiece, the Xtool system may not be as practical. While it eliminates the need for taping down and scoring paper, the trade-off might not be worth it. In scenarios where you’re crafting a custom cutter, incorporating a probe may be a beneficial consideration.
