Engraving resolution can be set in Beam Studio by menu > "Edit" > "Document Setting".
Engraving resolution stands for the fineness and quality of the final result.
Get more detailed results when the resolution is set to "High" , but it takes longer to engrave the same file.
On the contrary, setting the resolution to "Low" gets rough quality but takes shorter time.
