I see your problem.  At .1 resolution in t2 you need your jpg to be at 254 dots per inch (DPI)  Your file is at 300 dpi.  Open it in inkscape and resave it a png with dpi of 254 and you should be right as rain.  Try the one I attached.

You can just resize it in T2Laser, but wouldn't this be better as a vector?

Hi Zax,yes I thought I had changed it to a vector in wintopo,but maybe i did something wrong.It's a very steep learning curve for an old fellow:).
If i understand correctly,i can open the png file in T2,and click on each line,and trace it?Does that than change the part to vector?thnx.

yes so a png, jpg, bmp, or any other image file cannot be a vector image.  You need to save it as a dxf file.  If you bring an image file in and do trace you are making a vector trace of the lines you selected.

Thanks to everybody for your help.I have now managed a reasonably good engrave.
The parts came out a tad smaller than I wanted,so i have resized test parts to 101%-105%,so i get a correct size output at a given input size.
I have a feeling this size change comes about between the various file manipulations.
Also,the actual lines on the drawings are very thick,and of course,the vector line is in the center of those.
Isn't this fun ;D

Inkscape has a Bezier tool. You can trace the image and curve the lines.  I think that might be the best option for you. As you know the dimensions you want. You can use the bezier tool then remove the original image and size the trace to your needs.
