Tool not reading a shape correctly

[drlarrye]

The attached file is for a "Shaper", which is kind of a hand held CNC machine.  Each part is supposed to be black stroke with black fill and be a closed path for the machine to read it correctly.  The quarter circle to the upper left and the quarter circle farthest to the right are not being read by the tool properly.  I can not find a difference between those 2 shapes and the others in terms of the mentioned conditions.  Can anybody else?

I use vector for vinyl cutting and don't know much about cnc.  I can see nothing in that file that would interfere with a vinyl cutter.  Can you say more about any error message you are getting?  Only thing I can think of to try is to reverse the path direction on those two objects.  That might do something, might not.  They all seem to have the same fill and stroke colors, stroke width, meter joins and butt caps.  Maybe someone else can see something

The tool picks the direction of cut so I can't change that.  The error is just that it reads it as an online cut rather than outside the line as it should.  If there is no difference in the different shapes (and neither of us could find one) it is probably an issue with the tool.  Thanks for looking.

If you want to rule out differences, do: Select all, Path > Combine , Path > Break apart. This will eliminate any style or path format differences between the pieces.

I will do that then try that on the machine.  Someone already took the file and opened and then exported it in Affinity and it worked.  Thinking back to last year when I asked a lot of questions, could cruft be the issue?  If so, is that something that just happens randomly?  Is there a way to prevent issues with cruft?

Thanks as always for your help

My thought was the tool might not like the path direction in the path.  Under the Path Menu is Reverse.  But this probably isn't it.  Path direction doesn't matter much in cut vinyl, unless your trying to optimize a cut so the knife doesn't skip around so much.

Not that I understand XML very well, but looking at the objects in the XML Editor, I don't see any differences among all the objects.  Those 2 objects look identical to the others.  So as far as XML, I don't see any obvious cruft.  Although it could be something that's more technical than I can recognize.

The only thing I can think to try would be to move those 2 objects slightly.  Even if you press, for example, the up arrow key, and then the down key (so it stays in the same place) for some reason, that sometimes makes something work that didn't before.  To be honest, I haven't seen it work in this type of situation.  But what the heck?  Another "can't hurt to try it" is re-save it in Inkscape.

Other than that, I would look at the cutter.  Since one of those objects is the topmost, and the other is the rightmost, maybe there's some kind of border for the machine?  Everything is inside the Inkscape page border, but maybe the machine has its own borders?  I don't know.  I don't have any kind of cutter, so I'm not sure what else might make sense to look at.  I'm just brainstorming at this point.

I hope you can figure it out.
