Lasercut parts scaling issues


Hi All,

I've been trying to rebuild what was done by someone else on an OpenROV. I'm working on Lasercutting some specific files, but I'm having scaling issues.

The lasercutter I have access to is a Full Spectrum. Essentially you print from Inkscape the printer. So my stumbling block has been Inkscape. I have been using DraftSight to edit the files (get the various components separated and put onto single sheets with their thicknesses) and then I have to export it into a format that Inkscape will work with. Both SVG and PDF seem to result in scaling issues.

Is there any special technique here that would help Inkscape provide the right scale on import?
