X Axis spacing problem (not step calibration)

Hello, Im new to the community and I am wondering what I am doing wrong? (I’m sorry if Im not making sense, english is not my firts language)
I have a ruler file that I want to engrave and cut, however when I send the file I noticed the milimeters were not spaced evenly, I tried adjunsting the speed and the only solution I found was to send them by layers.

What I noticed is that if I make the lines the same lenght it doesnt happen
If I send them at the same time even if they have different colors same happens

I know its not the axis step lenght, the one milimeter distance is correct, the problem is that it somehow after 10 cm one line is not centered.


Thank you in advance

Can you upload file so we can look at it?

Yes, the file is a DXF one
