It seems like with common line cutting you’d lose half the kerf width off each part that shares a common line right? Since it’s technically cutting an open contour now?
Also, yours dosent look like it merged common lines. But on parts that small maybe it doesn’t try to match e dry small segment?
Have you had any issues with how it converts curves to segments?
I think the common line stuff is for laser, not plasma. I’ve not tried deepnest.io with common line (parts share cut lines) but I don’t think that will work right on plasma.
Common line will work for plasma, laser has a kerf width same as us right?
The curve to segment comment comes from the deep nest settings description. It even shows an example of a circle with multiple straight lines instead of an entire arc.
I think that is the issue - the kerf on laser is much smaller and more precise. Try it - it may work. I leave spacing about double the .06 kerf I use - about .125 as @Fortifyfabworks mentioned above.
I’ve never tried using the common line before I just assumed it wouldn’t work with the plasma kerf width but even if it compensated for the kerf width and it gave you proper sized parts in the end how would you get a cut path generated for it. I cant think of a way I could get fusion to be happy with it, probably have a little more luck with sheetcam but I don’t use that very often so I’m not sure.
Hmm. My local laser guy told me his kerf on 16 gauge mild steel is about .031. Maybe it was a typo and he meant .0031? Hypertherm book specs show .029 for fine cuts at low speed.
If I was just doing artsy stuff or my firepits, I could totally live with a .015 difference in the size. Shoot, I could probably even absorb that in my bumper or battery tray design.
I’m having issues with uploading DXF files to Deepnest, hoping someone can help me out or give me some guidance. Issue is, when I upload a file only parts of the sketch are uploaded. For example I uploaded a rectangular part with holes. Only the holes were uploaded and were separated in different parts. Any help would be greatly appreciated!
@TinWhisperer wow this is awesome! So I did try cleaning it up in Fusion360 by removing the unnecessary lines. I saved that version and exported DXF file. I was still getting issues with only parts of the sketch importing into deepnest. What did you do after you removed the lines?
