Anyone have experience with galvo settings when etching anodized aluminum business cards, specifically QR codes that are imported and not generated using LightBurn?
The Pass-Through option produces the cleanest version of the QR code but apparently is not as readably available in comparison to paper printed. I’ve tried with several combinations of speed, power, and frequency to no avail. Frustrating to say the least.
Stainless steel alone produces ideal results but unfortunately there aren’t many options for coatings when it comes to business cards.
Any help with anyone’s experience is greatly appreciated.
