First, stick decorative paper on the oak board, then place the oak board in the machine working area for laser engraving and cutting, and then replace it with PVC sheet for laser cutting.
Warning:PVC laser cutting is toxic!!!
Other similar transparent materials like transparent acrylic can be used as substitutes.
For M1 Ultra, use the knife cutting mode to cut PVC sheets. If it's other models, it's best to use scissors for cutting.
Ps:
Applying a layer of masking paper on the surface of the wooden board can effectively relieve the yellowish-brown staining of the wooden board during the processing. But it doesn't matter if there is staining.Most of the staining can be wiped off with alcohol.
