1. Common Issues

1.1 When the varnish layer on the solid wood surface is too thick, engraving results in inconsistent depth and incomplete images.

2. Solutions

2.1 Increasing Laser Power to Enhance Engraving Depth

A thick varnish layer on solid wood surfaces can reduce engraving quality. Increasing the laser power allows the beam to penetrate through the varnish layer, achieving the desired engraving effect with improved depth.

2.2 Sanding the Varnish Layer for Better Engraving

If the thick varnish affects processing quality, sanding the surface with sandpaper or similar tools can remove the top varnish layer, enabling the laser to engrave directly onto the wood underneath.

2.3 Using Recommended Parameters for Optimal Results

Following the official recommended parameters helps achieve better engraving outcomes. Alternatively, suitable parameters can be selected from the recommended parameter matrix to meet desired results.
