I fixed this problem with the rising edge valid fix. I forget now which one was wrong, but on my Ruida they both match now, and one was false and one was true in my settings. Try both ways. If I had to guess it was my Y set to false and it should have been true, but just going by memory.
Good way to check if that’s the likely issue is do a test engrave on some cardboard, and set it to fill+line. If that’s the issue the engrave will be skewed, but then the line will go back and outline properly. That pretty much should confirm a setting and not hardware problem, that’s what I had.
