External CAM kernel error

[Anonymous]

I'm getting this error: 

Enabled feature flags: setup-sheet-viewer tool-library-v4-release

Invalidated: Generation failed

Error: Internal CAM kernel error. Please report through your support channel.

Yesterday everything was fine, but when I cut out the part, I noticed extra wood around some window cutouts as well as the part itself. Then I remembered that the radial stock to leave value was .2 and should have been 0. I changed it to .2 and now I'm getting this error.

To troubleshoot the problem, I changed it back to .2 -- still getting the error but now the tabs I had set look way too wide, wider than the tool diameter. I removed them and put them back but they're still showing way too wide. The default value changed to .125 in so I changed it back to .063 in which is the equivalent of the tool width of 1.6 mm.

Now I'm stuck and can't seem to get the toolpath generated even back to what it was. I want the radial stock to leave set to 0. I kept fooling with it and now the tabs look right in size and radial stock to leave is 0 but I'm still getting the error.

Your part is only .08" thick, what presents you with the need to leave .2" on the depth?

The Internal CAM Error is being cause by a combination of the excessive Axial stock to leave and the Multiple Depth setting. Turn off one or the other and it will work. It will also work up to an axial offset of .0799", so it appears it's acknowledging the actual model thickness

That’s correct, but the actual problem for me was that I had .2 inches when the stock was .190” thick. I needed to convert the .2 as though it was millimeters to inches which left a value of .008” for the axial stock and 0 for the radial stock. That fixed the problem.

Here’s why I needed to convert the .2 to actual inches. Before I noticed the problem with my part, I had cut one out and saw that there was a large amount of wood still in the window areas and that the door measured a lot wider than it should have. That’s when I remembered that I had checked the box for Stock to Leave and had a value of .2 and .2  in the boxes for radial and axial stock to leave. But that was due to the bit I had originally used which was 1.5 mm and my wood dimensions were based on millimeters as well.

I redrew the part and switched to inches for my measurements so when I discovered that the part was too wide by about .4 mm, that’s when I noticed it was because my settings were left from the bit I had originally chosen previously. I had changed to a .062” bit so I needed the distances and measurements to be converted to inches. Converting the original .2 mm to inches made the value .008” (rounded). I changed the .2 to .008 “ for the axial stock and 0 for the radial stock dimension. That fixed it and it works fine now -- no errors or warnings and the part matches my drawing.

So the problem I encountered was simple — operator headspace (in other words, my own mistake).

Thanks anyway,

Here's something that might just blow your mind; you can interchange units in Fusion! Just follow a .2 with an "mm" so it looks like this: .2mm

Same thing goes for Imperial; .2in or .2" will get you the Imperial equivalent of metric, which would be 5.08mm

I didn’t know that. Thanks for the tip.
