V-carve simulation differences on beveled edge with 2 identical toolpaths

[jadlp3742 (Joseph DeLaPaz)]

Does anyone know what would be causing the
V-carve toolpath simulation differences shown in the screen captures along the beveled edge between these 2 CC files? Same workpiece, same vectors, same toolpath definitions, same cutters, but V-Carve toolpaths were created from 2 different CC files running the same CC version 838. One CC file created on my laptop PC and the other created on my desktop PC. They should look the same.

The one on the left with the red circled area created on my desktop PC. The one on the right with the green circled area created on my desktop PC. Both PCs running CC838. The beveled edge on the right screen capture goes all the way down to the floor of the cut pocket. The beveled edge on the left screen capture ends halfway down before reaching the bottom of the pocket.

I can’t get them to match in the simulations. The beveled edge to go all the way to the floor of the cut pocket.

This looks similar to this problem:

V-bit not cutting to same depth as pocket tool in advance v-carve operation

Hi there. I’m using a Shapeoko Pro XXL with the latest Carbide Create software and a BitSetter, and I’ve set up and run several advanced v-carve operations where the v-bit cuts to a depth a few millimeters above the depth of the pocket end mill. This issue shows up in both the simulation and in the milling operation. Here’s an example. I’m running an advanced v-carve using a Carbide #201 for the pocket and CIC’s 30-degree VSC30 for the v-bit, using standard settings for both, with the exception…

Is the V Bit using a C3D built-in definition, or is it a custom tool? If custom, how did you go about defining it?

That thread came to the conclusion that if the tool definition had a non-zero ‘corner radius’, then that was messing things up. The value should be ignored for V Bits, but apparently there’s a bug where it isn’t. It just doesn;t show up often because zero is the natural value to put in there.

Do both instances of CC have High Res Simulation enabled?

[jadlp3742 (Joseph DeLaPaz)]

Both instances of CC have Hi Res Sim enabled. However, I believe I discovered the cause of the issue I described. It turns out I have the vee cutter’s tool file in the PC loaded with a corner radius setting of 0.125" and the laptop PC tool file for the same vee cutter was loaded correctly with 0.0" corner radius. Changing the corner radius to 0.0" for this cutter on the PC tool file resulted in the bevel edge to go all the way to the pocket floor. Something to watch for going forward when loading new cutters in the tool file.

Thanks for the follow for the rest of us to learn from.

Good to see you found the problem. I keep my CC designs and tool files on OneDrive so if I use a second laptop (rarely) then I’m using one location to pull files from and one tooling master file.
