Sculpfun S6 Pro — 3mm Basswood Plywood

4 passes at full power barely cuts 3mm basswood — results are unreliable with heavy charring. The S6 Pro is an engraving machine, not a cutter. Limit cutting to 2mm balsa or thin card. For wood cutting, a 20W+ machine is the right tool.

The S6 Pro's 6W module engraves wood cleanly. 60% at 3000mm/min gives a warm brown mark. A solid entry-level engraver for personalised gifts and small craft items. For darker marks increase to 75%. The S6 Pro punches above its weight for engraving given its low price.

S6 Pro needs 3 passes where S9 needs 2. Keep power below 90% to avoid overheating the diode. Air assist significantly reduces passes — add it and drop to 2 passes. Constant power mode. Ensure material is flat to the bed.

Good starting point for fill engrave. Bump to 60–65% for darker result. Use dynamic power mode in LightBurn. Forgiving material — grain absorbs consistently. Run a material test grid first.
