Troubleshooting Guide: Understanding & Preventing Baseplate Marks on xTool M2
If you've noticed slight marks or engraving traces on the metal baseplate of your M2 machine, this is a normal phenomenon — not a product defect.
🔍 Why This Happens
When the laser beam cuts or engraves through your material, the residual energy can pass through and leave marks on the baseplate underneath. This is a general characteristic of laser processing equipment, not a quality issue, and it will not affect the machine's normal operation or your engraving/cutting results. Even with long-term use, this will not cause the baseplate to leak light or become structurally damaged — this has been thoroughly tested to ensure safe long-term use.
💡 No special treatment is needed if the marks don't affect your usage. Regular light cleaning is enough for long-term stable use.
If you'd like to better protect your baseplate, here are some recommendations.
🛠️ Baseplate Protection Recommendations
Place a flat, non-flammable, non-reflective protective sheet underneath your material during processing. Suitable materials include:
🔹 Black anodized aluminum plate (≥0.8mm) — should not visibly deform after laser processing.
🔹 Other non-highly-reflective black metal sheets (any thickness).
🔹 Acrylic sheet (≥1mm) — black is recommended; other colors may interfere with material contour recognition. If processing multiple small items, check that the distance-measuring points are correct, or use manual distance measurement to avoid errors caused by the added protective sheet.
🔹 Heat-resistant silicone mat (≥2mm) — silicone tends to curl or warp, so choose a thicker mat for better flatness. Black is recommended; white silicone also works for protection, but check distance-measuring points when using automation features. Not recommended for cutting paper materials directly, as it may worsen scorching/blackening.
🔹 Other materials: black flame-retardant welding mat, black carbon fiber nylon cloth, silicone-titanium alloy soft pad (black or gray).
📐 Placement Guidelines
The protective sheet's size should be:
🔹 At least as large as your processing pattern.
🔹 No larger than 380mm × 320mm (the machine's work area).
🔹 Ideally under 8mm thick — a pad that's too thick may reduce your effective processing depth and can affect concentric circle recognition.
Reference placement zones:
🔹 Zone 1 (green): Reserved space needed for the print head's upper/lower cover clearance.
🔹 Zone 2 (red): A 330mm × 320mm protective sheet, placed against the silkscreen markings.
🔹 Zone 3 (blue): A 380mm × 320mm protective sheet, placed against the right side of the machine.
