The A40640 features an ultra-lightweight body that drastically reduces scanning inertia, delivering sharper image engraving with minimal motion blur. Its pioneering adjustable-focus optical system sets it apart: the long-focus configuration excels at curved-surface and uneven-material engraving, making it ideal for large-area coverage on irregular workpieces, while the short-focus setting delivers higher power density and resolution, perfect for metal marking and detail-intensive projects.

As NEJE's groundbreaking debut of spatial optics in the blue diode laser field, the A40640 established the design language that continues to define our modules today. With tens of thousands of active users worldwide, it remains one of the most trusted and widely adopted diode laser modules on the market.

Anyway, last week I started to engrave slate. Wow! That's something!

I would like to know if there are any upgrades I can do or do you suggest just repurchasing the A40640. My machine is 2s max machine.

I recommend repurchasing the A40640 laser module. The E80 24W, 4W IR, or E160 50W 8-FAC are heavier-duty modules best paired with the high-rigidity Max 4 V2 platform.
