Hello, I recently bought an Xtools P2S, and I was working on engraving some logos. However I noticed an issue that at the start of a pass the engraver is fine, but as it reaches the end it is much fainter of an engraving. In my test I did 2 passes so I can confirm that it's due to the end of a pass because when it went to do the second pass it was strong, then as it reached the bottom it was fainter then the rest.

Is this a setting I might have to modify, or is it an issue with the laser, any help would be great.

Thank you,
