Regular maintenance keeps the pen performing at its best. Users should clean the tip after every major project or when switching between different materials. Frequent cleaning prevents residue buildup, which can cause uneven lines or skipped sections. For heavy use, a quick wipe-down after every session helps maintain consistent engraving quality.

Settings

Speed

Speed settings play a crucial role in engraving results. Slower speeds allow the tip to engrave deeper and create darker marks. Faster speeds produce lighter, more delicate lines. For materials like silicone and rubber, moderate speeds (300-500 mm/s) paired with low power settings (10-20%) prevent burning and ensure proper depth. In wood engraving, adjusting speed helps control thermal effects. Slower speeds can cause burning or charring, while faster speeds reduce these risks but may affect engraving depth. Users should always test different speeds on scrap material to find the optimal setting for each project.

Pressure

Pressure settings also influence engraving quality. Applying too much pressure can damage delicate materials or cause the tip to slip. Too little pressure may result in faint or incomplete lines. For rubber and silicone, excessive air pressure can lead to overburn or blurred designs. Lower air pressure often improves engraving by reducing flare-ups and preventing burning. In wood, air assist helps clear smoke and debris, improving clarity and edge smoothness. Users should adjust pressure based on the material’s flexibility and thickness, always aiming for clean, precise lines without damage.

Tip Replacement

Worn Tips

Over time, engraving tips wear down and lose their sharpness. Signs of a worn tip include uneven lines, increased resistance, or visible flattening of the tip. Users should inspect the tip regularly and replace it if they notice these issues. Continuing to use a worn tip can damage both the pen and the material.
