Hi everyone,
Three months ago, I generated a path that worked fine. Today I went back to this project and there is a problem with generating the path in several pockets even though I did not make any changes. I just loaded the model.
Changing the extension method doesn't help.
Has anyone encountered such a problem?
It's possible that something has changed in the toolpath calculation. Could you share your Fusion file?

The point of failure seems to be the Left/Right cutting method. I'm not sure of a solution (at this point), would it be possible to cut that one pocket in a Left (climb) manner?
Quite likely. The other very valid option is to use 2D Contour and turn on Roughing Passes:
Result:
I'll get a ticket logged this morning as soon as some time frees up!
Different "workaround" for this bug, instead of selecting bottom faces I tried selecting the bottom edges of all the pockets and this seemed to work quite well as it does the shallow pockets before the deep ones which would be logical, assuming you want to use pocketing IMHO 🙂 🙂
Example File attached.
But note that your example also has an error in the generated toolpath.
Similar as below:
In addition, with 650 pieces, it unnecessarily extends the processing time.
Yes, the issue does not seem to be fixed 😞
However, a "workaround" that I have found is to create a new pocket and it seems to work OK, still a great PITA but can be rescued.
It would appear that the original 2D Pocket is somehow "corrupted" and creating a new one works OK 🙂 🙂
The problem arises when you change the direction of machining to the right (conventional).
Works OK here, see images below and attached file.
I did make some changes to the entry method, ie, disabled the Leadin/out and changed the Helix Diameter.
I also selected the deeper pockets first and then the shallower ones and enabled the "Preserve Order" and the deep area is machined first so the shallow areas can be done from outside the small area so it is plunging into air as the main pocket has already been cleared 🙂 🙂
Works for me anyway, does this help you ?? 🙂 🙂 🙂
Quite possible that some changes have been made to the 2D toolpaths and it is a matter of learning the new way, any ideas Seth ??
As mentioned in your other thread, this issue has been logged as CAM-37410
@Protective-foam_com The initial ticket has been fixed (back in June/July), but it's possible there are still outliers that present an issue. Please share your Fusion file here and I'll try to see what's going on
