It's been so long I couldn't recall for sure so I went to the CB program file, checked properties and other than Verion 1.0 I'll be darned if I can identify whether its 32 or 64 bit. How do I identify that? There was a file in the CB folder fade2D_Win32_v120_Release.dll

Go to Help/about CamBam menu

In the info panel it will be named CamBam plus [1.0] x64 if this is the 64 bits version, and only CamBam plus [1.0] if this is the 32 bits version.

Of course, the 64 bits version can only be installed on a 64 bits version of Windows ;)

Must be 32 bit because only says CamBam plus [1.0].

Best,

Hi dh42,

Thanks for creating this plugin!

I was trying to unroll a specific model that crosses the rotational axis. This makes the contour go below zero and it gets set to zero by the plugin. This is unfortunate, because it would theoretically work fine with a negative value. I assume in the plugin you make use of selecting the positive value (top side of the contour curve) and omit the negative value (bottom side of the contour curve). If there's no positive value, it picks zero. Am I right?

Would it be possible to change this to "Pick the most positive (or least negative) value of the two"?

In that case it would also be possible to unroll parts that go outside the centerline.

Like this part https://www.thingiverse.com/thing:5594366

It should works if you define "Z min" to the negative position to achieve.On the example, the lower part is at ~4.4mm under the axis so I set a value of -6 in Zmin

Hi David,

Thanks for your quick reply!

I do only now realize that those flat parts are actually correct...
The part moves away from the YZ-plane, so at some rotations there is nothing to mill with the mill constrained to the XY-plane...

Which would mean I'd need a different solution for actually milling a shape like the one in your example. Because you'd need the mill to leave the XY-plane...

Thanks for taking the time for me though. Much appreciated. And your tool is still very helpful to me in other situations.

Hello

In this case you needs "true" 4th axis machining, but only high end soft can do that ($$$$ !!)

A free one exists but I never tried it (CNCtoolkit + Gmax)
https://cambamcnc.com/forum/index.php?topic=5007.msg39034#msg39034

Maybe Fusion360° can do it but not its free version, you need a license for the 4th axis features to be enabled.
