Some weird stuff with multiple parts

So,
When I work on my laser 1 piece everything is fine... Just perfect
.
But..
When I use array in rd works with the same settings I get every time this blurry effect. Pictures attached.

Is it possible that this is not related to "one piece" versus "array"? Could it actually be caused by the position on the bed of the laser?
For example, if you always cut a single piece at the upper-right part of the bed, but when you do an array, it's the piece at the lower-left that is blurry?

Good idea.
I have noticed that also. And I need to check how is table leveled.
But something is different when i working with array when there is scanning involved. I noticed that some days ago. when I am working just with cut settings with different power nothing special happens. but when I work with scaning I have problems with sharpness and also sometimes with centering the vector inside the pice. the first in an array is ok, but then every single pice has vector scanning a little bit more out of the center. Cutting the pice, in the end, is position in the right spot.

Sounds like you have "backlash". This is caused because mechanical parts don't fit together precisely - there is always a small gap between parts. I think that if you search this website for "backlash" you will find a tutorial on how to fix it.

YES,
it was backlash...
amazing how easy was this to fix. Also, I have set up reverse intervals and now laser works like a charm.
TNX... you guys are awesome!!!!!!!!!
