Inkscape to luban

Hello, when i have a drawing in inkscape the drawing is in mm and that is correct. I save the file in svg or dxf and that wil open in luban. Why is the measurement than not correct ? Not only the convert from edit to proces goes wrong but the A4 is not A4 any more.
I have changed the luban version but that makes no difference.

Is it possible to laser directly from inkscape or any other program then luban. The luban is very good to print a name on a tile.

I draw a circle of 5 cm and a square of 5 cm and the laser result is every time different.

Please can anyone help me i tried it now for many times but no “good” result.

Unfortunately it’s a problem that hasn’t been fixed.
Workaround is to enter the dimensions of the file in the size in Luban and then you should be fine.
You can also use the grid in Luban to figure out the size of things.
