I didn’t read the entire problem. Looked like a skewed engrave.
Ok, this is what i found, when i use fill with cross hatch OFF, no issues. When i turn it on, it burns the image once in left to right direction, the second direction, up and down seems to be about 3 or 4 mm to the right side of the original image. This is whats causing the double image. I found the issue, but what the hell is causing it??
I have had exactly the same issue. Redraw the item and it ran ok. Sorry cannot be more help
Ok, here are some more results and tests.
When I cut the image with only one layer, No problem. The issue happens only when I cut a second layer. I tried the following.
Cross Hatch, multi layer at 45 and -45, and even the same layer, but run twice. The result on all of the above was a double image.
This leads me to think its a mechanical issue?
I would assume its not a laser issue as the point of the laser should not move, even if it were out of alignment. For example, if it were 3 degrees out of alignment to the left, no matter what direction i started from, it would still be 3 degrees to the left.
Could it be slop in the belts? Stepper issues? Freaking loose doohickey causing the thingamajig to slip!
Any suggestions would be appreciated, any links to video’s that may address the issue would be very appreciated!

Ohh, and I did reintroduce the image fresh, and re did all the layers new.
I remember back a ways, but it stated not to use scan angles that are not in 90 deg increments… on a Ruida

i tried downloading the file to usb, and transferring from there to the laser, then printing directly from the laser. Same issue.
This time I did a box, first layer the line, notice how its square (4 90 degree sides). But the fill (same image as the lines) seems to skew to the right. I cant figure out why on line form, its perfectly straight, but ONLY while doing fill the issue arises.
The error is proportionate to the size of the overall drawing. If this is the case, it would lead me to believe it is some form of stepper or setting issue?
Does anyone have a Laguna MX, could i compare your stepper numbers?
IMHO - don’t mess with those 
Your system is digital up to the shafts of the steppers. You get a perfect rectangle in one instance, that tells you the hardware and configuration is probably ok for the positioning…
Do a small square with and without fill. Make the square and use ‘duplicate’ to copy, move it to a nearby location and change it’s layer/fill no fill…
Are you using flood fill?
Ok, next test. Made 3 inch square boxes, over the size of the bed. With one large line box around the whole thing. The lined large box, and 5 smaller lined boxes came out perfectly square. Bit when i filled the boxes, as you can see, the fill was askew. The fill became more askew as it progressed from the front to the rear of the machine. I ran this from my computer, and then via USB. I even tried loading Lightburn on a new computer. I checked the bed, and its level to the laser head on all 4 corners.
I assume that the fact that the line boxes were perfectly square, the gantry must be square. Only the FILL seems askew.
What the HELL is going on?
I still think it’s a PWM issues. Go to machine settings and see what the PWM rising is set to on the x and y axis.
Read the article I posted earlier.
Please test leading edge vs trailing edge and let us know.
Well hell, I didn’t know that was a link, I thought it was an ad! Reading it now, and it looks like it matches my symptoms. Gonna try it out tonight!
Thank you so much! Imma let you know.

Ok, I tried the stock PWM settings to X and Y off, X and Y on, X on Y off, X off Y on. Item still skews, just to the left or right of the line cut box. The line box is set to 50 mm height and width, which is dead on per a caliper, and verified via diagonal measurements.
Im getting frustrated.
I believe the setting should be the same for both x and y. Both of mine are off.
I would try to do the same square test on all 4 corners of the bed and the center to see if there is any variation.
I would also cut this file out and check beam alignment at the nozzle in all 4 corners and center.

This file came from this forum but I couldn’t find it to link to.
Update. I ran the laser with all 4 possible pwm setting combo’s, all it did was change the skew from right to left. I have cut the boxes in all 4 corners of the machine bed, with the same results in each location. Im stumped.
FIXED!!
Ok, after everything i tried, belt tension, pulley tension, hardware and software it turns out one of the side dip switches of the x controller was initially set at the factory incorrectly, and sent to me in the wrong configuration. Laguna tech support over a week or so of texting and emails helped me to find it. All is good in the world today.
FYI x and y controller should have matching dip switch settings on both front and side.

What X controller? Are you referring to the motor driver?
