Hi, i am using Inkscape 1.3.2 on Windows. I have a simple drawing that i exported as a .DXF file to send to a laser cutting service. When i got the parts the cuts were very 'ragged' and basically unusable. The laser service told me there are extra nodes in my file but i can't work out where they may be coming from. I am attaching the .svg and the .dxf file here, maybe someone can help me figure this out. I used save as.. with DXF 14 as the file type. Thanks for looking :-)

When exporting out as DXF I use Autodesk DXF R14 file format and use the following settings. I find it more helpful if I use "Save As"  instead of export because this will force the DXF setting dialog to pop up. If you use export directly - you have to click the "gear like" icon to get to the settings dialog. I tend to forget to do that.
