Need help programming wind spinner

[swaymire13]

im trying to program a hummingbird wind spinner and cant seem to figure out how to get it to do the cuts for the thin lines that make the part for twist, any suggestions would be appriciated. i see all kinds of these being made but i cant figure out the programming.

What design program are you using?

What are you using for CAM? Fusion or Sheetcam?

If these are relief cuts for bending, they need to be a single line or a large enough loop to fit the kerf of the plasma cutting tool.

Fusion will not generate a toolpath on a loop that doesn’t have room for the kerf or lead in/out.

Spinner file - tool path problems

I have some time it AM so i am thinking about do a live stream walkthrough of a wind spinners CAM in Fusion 360. I ll get a fresh tea and start a stream soon This is the file ill use as an example if you want to play along. hum spin v2.f3d (618.2 KB) [hum spin v2] about 745am pst today

I did do a video and walk through of developing the cam for a spinner in Fusion. I’m just trying to find it.

My twitch stream video has long since expired I’ll see if I have it posted to YouTube or I have it in the archive and I can post it to you tube

You need to do a separate 2d profile that only does open chain cuts. Disable Lead ins, Lead outs, set the offset to zero. Select all of the “ring lines”.
Then you can do another 2d profile for the rest of the cuts using closed chain cuts.

this is for Fusion. I’m assuming you are using Fusion for this.

Spinner file - tool path problems

Check out this video on single line cutting it is my old workflow but it gets the job done. [Video 6 Creating Single Line cuts in CAD and CAM in Fusion 360 for a CNC plasma table] I’m planning on updating a few of these videos soon. A wind spinner would be a great example for a single line cutting video. And somewhere on the Forum I do have a screenshot by screenshot walk through of doing a wind spinner from a year or so ago.

Here’s a link to the video about doing both open and closed geometry in one piece.

can you post the DXF or F3D file you are using ?

Export f3d File and Post to Forum

Go to upper left corner and click on the File Menu Icon: [Export f3d-1a] Click Export: [Export f3d-1] Choose a location to save the file. Use the current location listed or change it by clicking on the square with the 3 dots. Make a note of the folder as you will need to find it later to upload to the forum. [Export f3d-2] For this Example, I am going to choose the “Example” file folder: [Export f3d-3] Once you have the location selected click export: [Export f3d-6] To upload to…

you may not be able to post a file yet but when see you post a few more responses that option will open up

[TinWhisperer]

I put together a quick video using that file showing a couple different options. See if that works for you.

Thank You @TinWhisperer I have had problems with open lines in Fusion360 before, and have abandoned a couple of things because of it. Your video was the answer to the problems I was having!

Good Job, Thanks again for posting that video.
