I assume you are using the print and cut feature, did you choose scaling or no scaling? It looks to me like a scaling issue since the bottom left cut is closer than the top right one. Try again using the other option.
Nvm still getting same problem,
left bottom corner cuts good, middle is offset by lets say 5mm x 5mm y and top right corner twice that.
If I use scaling then I get inconsistent shapes.
it cuts out like this,
it’s supposed to be 2mm outline on every piece, instead it drifts off in different ways
I use two files, one to print - with the outline
another file for laser, where outline is created from the piece of color itself without the 2mm outline, with Xs placed at same spot
It’s likely the printed page does not match the intended dimensions, making the laser seem incorrect.
In Illustrator, add four targets to your design at the corners of a rectangle with known (and easy-to-measure) dimensions. On an A4 portrait sheet, that might be 150 mm horizontally and 250 mm vertically. Print that sheet as usual, then measure the target distances using a good-quality (steel) rule or caliper. In addition to the X and Y distances, both diagonals should be 291.5 mm.
If those dimensions do not match, then the printer has scale problems.
If they do match, import the DXF version of that layout into LightBurn as usual.
Align the printed paper target at the laser position
Click to Move on the upper right target
Without moving the lower left target, align the upper right target at the laser position
That may require a few iterations, but eventually you should be able to move the laser exactly between those two targets on the paper with Click to Move.
If the laser’s position does not agree with the paper positions, then the laser is not positioning correctly. That may be due to incorrect axis scale factors (Step per mm) or other problems.
If the positions agree, then without moving the paper, you should now be able to Click to Move between the lower-right and upper-left targets.
Note that none of that uses the Print-and-Cut alignments. It’s all simple positioning using targets at known coordinates.
If all that works, then you have verified:
The printer produces accurately aligned & scaled patterns
The DXF file contains those patterns at the proper locations
The laser’s physical positioning agrees with the printer
If that does not work, then there are problems that cannot be resolved using Print-and-Cut and we have more information to help identify the problem.
