F360 - I can't get this profile to cut

I have deleted and started over 3 times to get this stupid simple bracket to cut. I can’t figure out what I am missing.

Sheet metal, cutting the flat pattern. It does the holes OK, will not do the outer profile.

Help please

I could not get your toolpath to work so I deleted and started over.

Just deleted toolpath, so the setup is fine. You will still want to check my lead-ins/lead-outs. I was just trying to see if I could get the outer contour cut.

Perhaps Tin or Terrance or someone else would take a look at the original toolpath to try and figure out what is going on. I can’t figure out what it doesn’t like. :man_shrugging:

2nd Edit: Yours works now. I just changed “Compensation” from “In Computer” to “In Control”, but I don’t know the consequences of changing this. Reading the help instructions, it says that you will need to enter information later to allow for proper clearance for the kerf width. Above my pay grade.

Very odd. I looked at the original toolpath, and was able to get it to select the outside perimeter by turning off lead in / out. However, I was unable to change where Fusion wanted to place the leads regardless of what I tried. I suppressed the original toolpath and created another, which worked fine.

I also noticed that the original toolpath had an issue with the bend index on the upper right ( at the corner.) Didn’t seem to want to complete the path.

Even trying different cut profiles did not work. Chain, face contour outside… nothing would finish the outer perimeter.

And trust me jimmy (as Big Daddy calls him) is not cheap!

This is what I hate about Fusion. Unless you are using it daily stupid stuff like this pops up and is hard to figure out. I never know if I will find the problem or it’s better just to start over.

That is what I kept thinking that there was some clearance of the cut path or lead-outs/lead-in but why did it allow a new tool path with the same setup.

Thanks for taking a look Terrace.

Been there did that. 3 times. Would not cut the outer perim.

Glad you guys were able to get it.

I had to recreate as a regular sketch and dimention out all my “bend lines” and get er done.

Should have taken me 15 minutes. 2 hours later I am asking for help and going old school.

I found the problem, although I don’t know why Fusion 360 was so fussy.

For the cornering on the outside, picking “Keep sharp corner” was rejected but if you pick the other two options, no problem. The funny thing is that it is not a “sharp” corner!

Interesting. That may be a glitch. Reject a cut path because there are no sharp corners.

Weird though, It will do circles no problem.

So I did not look but is there both:
Keep sharp corners?
Keep sharp corners with loop?

Yes. It will run the program if you pick “Keep sharp corner with loops” but then it does not do any “loops”. Because it doesn’t need to:


Oh interesting, it looks like it skipped a section in the middle of the outside of the panels and skips the knotches. Not totally fixed.

Now if you pick “roll around corners,” everything is satisfied and you get the green check mark on the toolpath and setup:

Which leads to this statement:

:rofl: :smirk: :sunglasses:

All I can say in conclusion: “We all learned something from this little exercise.”

yes this element is the root cause

@Sticks

If you increase or reduce the size of the alignment notch it fixes the issues

or

removing the lead out will allow the path to generate but still with a odd flaw in the path at the little notch

Also your work flow for the notch and the holes, I would do it through a sketch with in unfold tool instead of doing it through the flat pattern. It will show better in the timeline.

It seems there was a time when I could not easily edit the flat pattern and you were forced to use the “unfold” tool.

Watch this.

There’s an unfold tool?

I know what you’re doing and it is not funny…well, it is kind of funny. :face_with_hand_over_mouth: :rofl:
