Hello everybody. First i want to apologize if my english is not very good.
I have a problem with a China laser when engraving stamps on rubber.
In the photo the engraving is in only one direction (when bi directional is checked overlaps).
the depth is also very little . Power settings 80% and speed 200.

Hi, how many times did you set for engraving?
Did you ever change other design picture for trying , is it the same?
Or did you adjust your focus distance ?

And how long did you use of your laser tube?
