Help - Grid Lines Not Straight

So I just finished my first engrave of a simple value chart. Even thought the squares for each value setting line up in the lighbturn file, the grids horizontal lines are not in the engrave as see in the third picture. I dont know if maybe the interval jumps are scooting the laser around just enough to move it out of place from the material or what. Thats my best guess at least. If anyone has any idea why this is happening and what I can do to fix it Id really appreciate the help.

(also I hope this is the right category for this if not I can move it)

If you set it to “engrave all shapes together” instead of using flood fill or fill individually, you’re much less likely to get those jump errors.
