Thanks for the replies .
So you say that the solution of david for my large scans is not suitable as it is structured for 3D.
You advise me to take pictures , put them together and then turn them into vector image ISO to be able to convert to G -CODE .
I was interested in the solution of david especially for accuracy , my fear is that by doing as suggested , the accuracy is not the best.
I state that I do not know software designed for this purpose , and I suppose to manually merge the images with paint is not the ideal solution
I also have another doubt : I tried to convert to vector scans of relatively small objects (a4 ) by using my scanner and the program of Vectric VCARVE 4 .
Ok for proper operation , however, creates numerous imperfection . For example, an oval shape instead of create me the linear path following the profile of the form , he create points / nodes, that interferes with the regularity of the design. Should I open the drawing , zoom in , manually delete these points / nodes and regularize the form . Practically becomes an absurd work .
I was hoping to find a better solution that would make me all the more uniform.
For this I thought of the solution of david, inserting the laser in the head of cnc, webcam fixed at one point and with the regularity of the movement, I was hoping for a more accurate and consistent.
Any advice on software what i can use for merging images and create vector? Thanks again for the help.
