I can open the SVGedit file in Inkscape, set the stroke color and line width since they appear unset to Inkscape, and after saving from Inkscape the process of opening in Illustrator and printing to the laser cutter print driver works ok.

I'm talking about a simple design of a circle with a triangle inside it, stroke color of 255,0,0 and stroke width of 0.1mm.

I tried swapping the XML header line and the <svg ....... > data but that didn't change anything.

Hello, I think you need to give more details on what means "unrecognizable"? what is the inkscape file content vs the svgedit file content ? etc...

Still hitting this wall and not sure what is causing the SVG from SVGEdit to not work with this laser cutter driver.
The circle create in Inkscape can be opened in AI, selected and set the stroke width to .001pt then printed and it shows up usable by the laser control software. But the SVGEdit file shows up at the laser driver as something to be raster engraved instead of vector cut doing the same operation of just changing the stroke width to 0.001pt.

Here is the same SVGEdit file but imported into a new Inkscape document, setting fill=none, stroke color=red, stroke=.1mm then saving and it now loads into AI and goes to the laser cutter as a vector just fine.

It seems to be something in the file layout. What I have the students do is create their laser cut design in SVGEdit then import into Inkscape, change/validate the DPI is 72 for Illustrator and change the line widths to .1 mm and use SaveAs to add "Fixed" to the file name then open it in Illustrator. This is hit or miss for some reason.
Yesterday I took a "Fixed" design file back into Inkscape, moved the designs to the side and recreated the designs fully using Inkscape drawing primitives. The designs were simple, a 250mm diameter circle with a 6mm diameter circle centered in the larger plus a line drawing of a 300mm long rectangle with a 100mm indentation at one of the narrow ends. Literally just 8 line segments. The previous drawing elements were selected and deleted then this was saved over the original "Fixed" file and still when Illustrator sent it to the laser cutter it was getting engraved instead of cut. Line width and color are important factors in what the laser cutter driver will do with the design. Red for cut, black for engrave and the line for the cut needs to be very small, .001mm.

I went back to Inkscape but this time created a new drawing within Inkscape, created the designs, saved as Inkscape SVG file(same as before), and this time Illustrator and the laser cutter driver accepted the design as intended, ie a cut not an engrave.

So it seems like something within the SVGEdit file XML is causing problems for the laser cutter driver. We will be replacing the laser cutter machine with one I have admin control over and I'll be updating the laser cutter driver and I will then retest to see if the same thing happens.
