Before placing the shape on the grid, mark the center of the grid (50×50 mm) on your shape with a small pen dot, pin prick, or pencil cross. To find it: align your shape over the printed grid and make a mark at the red ⊕ crosshair. This point is exported as the DXF origin reference on the red AXIS layer — your cutting machine operator uses it to align and position the material.
The best result is a shape with a dark, high-contrast color placed directly on the white calibration grid. Black, dark blue, or any dark solid color works perfectly.
For light-colored shapes, place them on black paper cut to the same outline, then scan the silhouette. Transfer the ⊕ axis mark to the black paper too.
Lay the glass over the printed grid and mark the red ⊕ crosshair position (50×50 mm) on your glass with a wax pencil, tape marker, or a small sticker dot. This mark becomes the reference origin in the exported DXF.
Trace the perimeter of the glass shape with a black permanent marker or a thin strip of black electrical tape. The scanner will pick up this outline precisely.
Apply a thin, even coat of washable matte spray chalk to the glass surface. Wipe off afterward.
Place the glass shape on paper, trace outline with a black marker, scan the paper tracing. Transfer the ⊕ mark to the paper too.
Use diffuse, even lighting — avoid direct sunlight or spotlights that create harsh shadows. Overcast daylight or an LED panel is ideal.
Hold the camera as parallel to the grid as possible — directly above, looking straight down. Aim for less than 30° tilt.
The entire grid (including corner markers) must be fully visible in the frame. For 100×100mm shapes, ~30–50 cm height is typically ideal.
Tap the grid on your phone screen to force autofocus. Use a rigid mount or rest your elbows. For best results, use the Load Image option with a photo taken by your phone's native camera app.
