Hi everyone,
2 years ago, I engraved qrcodes on anodized aluminum cards. The result was neat and clean.
Today, the engraving is bad. The edges are all blurred.
upper left: 2 year ago, not blurred / upper right: today / below : toolpath from Luban
Settings tried
Image formats tried: PNG and JPG
Processing mode tried: B&W and vector
Toolpath settings: line-filled engraving and vector engraving
Line direction: horizontal and vertical
Jog speed: 1500 to 3000
Work speed: 1500 to 3000
Constant Power mode: on and off
The problem stay the same
I’m using a PNG image of a QRcode generated on the Internet. I’ve also tried using JPG images.
When Luban generates the laser trajectory, everything seems normal. But once the part is out of the Snapmaker, the result is really bad.
The aluminum card is fixed to the bed with the small pieces of silicone supplied with the Snapmaker.
Has anyone ever had this problem? If so, how did you solve it?
Thank you in advance for your answers
