Toolpath Out of Date

[Anonymous]

Hi all, fairly new to Fusion360. Using the Hobby version on a MacBook. 

My issue is that I’ve created several toolpaths to machine my model which will generate and save without issue. However I’ve noticed that just closing and reopening the file will automatically Mark the toolpath as out of date, even if no changes have been made. This is pretty annoying since it can take 10 minutes or so to generate a toolpath since my laptop is a little older. Just wondering if this was normal operation for the software if I’m doing something wrong?

Yes that is normal. Any tool paths that you what to "lock" complete and make it so they will not regenerate is to right click (in windows, not sure what the same is in Mac) and select "protect toolpath".

Well....yes and no. It's not an intended action, but it does happen on occasion with more involved selections. It's one of those bugs that hasn't been able to be reproduced with a measure of reliability. It "shouldn't" be happening all the time, for sure. For example, I'm able to open up many files all current and no invalid toolpaths. Very small sample size, I'm aware..

Well, it's not really an "invalid" tool path. Just that it's out of date.  I found a "Protect" option in the Mac version so we'll see if that keeps them in place and doesn't outdate them.

So is there a way to bring them "back into date" rather than have to redo them all?

[seth.madore]

Sadly, your only option is to Protect them before closing the file. This is not an ideal solution, but it's what we have at this point.

How can we "protect" toolpaths on Windows? 

I'm experiencing this same problem of toolpaths going out of date when closing then reopening a file. Definitely not an acceptable outcome as you literally have only one shot to complete your CAM or you have to start over.

Protecting is available on Windows too.

I would like to try to understand what's happening here. Are you able to share a model with which this occurs?

Thanks,

Hi there, 

Just saw this while confronting a similar problem on my Mac. Although I am knew to fusion 360 and literally spending 6 hours a day trying to learn all I can, I thought I should help those who might end up on this threat. The solution to the problem ofcourse is making soure that you right click your setups on the browser bar and turn them to "protect", however, if you did not do it at saving, all is not lost and you don't have to spend valuable time redoing the paths. All is right there. All you have to do is right click the path and select "edit" It should be the first in the latest version of fusion on the right click menu.  On the on the tab that comes out, take a look and all right there (tool, geometry, heights, e.tc). Look through it to make sure you're settings are correct and just hit "ok" and repeat or the different paths and thats it. You will notice that the red errors messages are gone. Hoping this helps.

I also see this program behavior often. More often than not in my experience. My workaround has been to select "Setups" in the manufacture workspace, either by selecting and using the hotkeys Ctrl+G to re-generate all operations or by right clicking and selecting Generate.

This is an inconvenience to all of us but my thoughts are that because Fusion is pushing the Cloud based approach, that since the information for each file is not always cached locally, is the stem of the issue. In all other Cad/Cam software files are generated and saved locally on your computer. Meaning that the generated operation information is retained in the file when saved. In Fusion your files are generated locally and  Cached locally in my opinion as "temp" files (though I do not know in what capacity) and at the same time synced to the Cloud. Since files are synced to the cloud after an amount of time (I have no idea how this is actually engineered) the Fusion software dumps your files info from the local cache and then you end up seeing the out of date operations on opening files. The above info is only my opinion of how Fusion works and in no way reflects any solid knowledge of how the software is engineered.

Often I have seen that Larger files with more operations and more complex toolpaths end up having out of date toolpaths more than small, simple, low op count files.

I have a similar problem, but it isn't a tool path throwing up the error. it is the NC Code. It reads "NC Code out of date" I have tried re-posting and saving, but it is still there. any ideas on that?

try redownloading the post youre using. it couldve been actually updated as a whole by HSM. so check the HSM posts page and see if its been updated recently.

What nightmare. There's always an issue! So frustrating!

[seth.madore]

@TAILSBAGPIPECO what exactly are you experiencing with Fusion, is it related to the topic that was being discussed in October of last year? We've done a bit of work to reduce the instances of this happening, but it's possible there are still some edge cases that are triggering such a warning. For example, in my own files, I'm finding certain toolpaths such as Trace and 2D Contour will exhibit this if I've also applied a Toolpath Trim to them.

[TAILSBAGPIPECO]

Hi Seth, yes I'm having that issue when I use 2D Contour and used
the 'trim' tool (if I understand you correctly). Also, if it does
eventually decide to work, it doesn't generate a smooth cutting path, but
it wants to drill up and down all the way along to cut the design out. I'm
just very frustrated after trying to get the hang of this for so long now.
Thanks for your reply.

I hit the "NC code out of date" error reliably when working through the Intro to 2D Machining tutorial...video 15, "NC Program".  I'm using the sample file provided by AutoDesk as part of that tutorial.  The first NC program creates just fine.  When I right-click it and duplicate the file, it immediately shows the yellow warning...hovering over that shows "NC code out of date".  If I click the yellow warning, the resulting window shows no errors, no warnings, no hints, no information, and nothing for debug (they're all checked and the area that should provide info is blank).

I read the thread above, deleted my NC programs, regenerated all of my toolpaths, protected all of my setups, then created the first NC program...it was fine.  Right-click to duplicate it and immediately shows "NC code out of date".

I exported the file to my computer and attached it here.  I've also attached the screenshot of the error/warning/info/debug window showing every option checked and nothing visible despite the NC code being out of date.

Very very new to Autodesk here, how do you protect the toolpath? My error says toolpath out of date.

Right click on toolpath and select "Protect"
