I don’t understand your question. What are the problems you are having? Can’t you cut through your material or what is the problem?

3

The cut don’t follow the photo. The vector cut are very very near to the photo but when I cut the cut is far away from the photo in the upper side of tje photo

It looks like your cutout line has moved up from the position of the image a little bit.

  1. You lifted the material and put it back.
  2. The material moved.
  3. The laser frame moved.
  4. You bumped the table everything is setting on.
  5. One of the two layers (image or cut) in Lightburn shifted slightly.
  6. You are not using Absolute Coords.
  7. There is a backlash issue with the Yaxis.

Nithing of these :sad_but_relieved_face:

Could be the axis driver? Loosing power? Because the image seems to be a little enlonged

Losing power would make it shorter or narrower. Use a tape measure if you do not have a calibrated eyeball.

My opinion is that the entire cut outline is moved up. If something is slipping or underpowered, it would be visible in the image.

Using cardboard so as to not waste good wood, make a big oval (C01). Then make a copy and make it a new layer (C02). Shrink the second about 5mm. Then run both to see if the second is centered in the first. You do not have to Cut, use just enough power to mark it.

Let us know how it turns out.

Sorry for the delay and thanks for this explanation. Your project file has no errors that are responsible for your problem, as far as I can tell.
I agree with @MikeyH , there is some physical movement of your project or drop of steps of your laser. The suggested test are a good start to find out where the error lies. Sometimes you will also be able to see this if you run a square with an offset copy, something faster than “normal”. (star shape also works great for that)
