Ran some tests and the file seems ok except for one minor issue related to travel limits.
My specs:
40w FSE Hobby Laser
RetinaEngraveV4-7-22 software and related firmware
Digital Power (not 10 turn pot) enabled
System: WinXP Pro with limited ram
The part of the card with "Epic | Consulting" written on it causes my gantry axis to bang into it's limits on both ends at the top and bottom of that section. This is related to the lines hanging off the edge of the card, likely just a little too far. I'd recommend laying out the cards exactly edge to edge and separating them with a single cut line, or spacing them a lot closer together. I vector cut cardstock at 75% speed, 3% power, 1 pass and can leave literally 0.008" between the cuts themselves (which is the thickness of the cardstock itself). The gantry banging seems to have caused a misalignment of the image but it is localized to the spots where the banging occurred.
As you can see, I've tested at several different raster settings:
25s/12p/250 DPI
85s/20p/250 DPI
100s/40p/250 DIP
I don't seem to have the misalignment on the vertical line segments that are apparent in your images.
