¶ Issue Description
The surface of the toolhead camera lens may become dirty due to dust, grease, or organic vapors. This is especially common after long printing sessions with volatile materials (such as ABS) or when using the laser module, since fumes and fine particles can accumulate on the lens.
A dirty lens reduces image resolution and contrast, which can negatively affect the camera’s performance. Regular lens cleaning helps maintain clear imaging and stable device operation.
