error after installing

in Rhino 8, the following error messages appear at grasshopper startup:

Object: KUKAprc_ToolpathOptimizerComponentV2 (level 1)
{
Exception has been thrown by the target of an invocation.
TargetInvocationException
}

Object: KUKAprc_ToolpathOptimizerComponentV2 (level 2)
{
Method not found: 'Boolean System.IEquatable`1.Equals(KUKAToolPath.GraphPaths.IPathSegment)'.
MissingMethodException
}

Object: KUKAprc_ToolpathOptimizerComponent (level 1)
{

}

Object: KUKAprc_ToolpathOptimizerComponent (level 2)
{
Method not found: 'Boolean System.IEquatable`1.Equals(KUKAToolPath.IGraphPathSegment)'.
MissingMethodException
}

is this a r8 - related error? most r7-plugins work in r8...

Requirement to kukaPRC tool path optimizer

Hi, My friend,
I hope this email finds you well.
Glad to write to you to require a beta test for the new version Tool Path optimizer. I met some problems in recent research and design of kuka robot tool path programming. And according to the video you showed on Youtube, it will be a good solution for me. So I hope you can give me the right to test it.
Looking forward to hearing from you!
Best regards,
Ziqiu Huang

First Trial Issues

Hy Ali,

I have some issues using the plugin.

1.My robot is using the z-axis as tool axis but it seems like your plugin is not reacting to it because it is directing to the x-axes of my planes.

But the rotation must be around the z-axis.

2. Its using 100 % of my CPU and calculating very long ( like 10 min or more ) and I have a powerful thinkpad. Also when im just calculating with 10 frames for my path. Could it be problematic because I´m also using a turntable and the cell ?

3. Is it programmed for Rhino6 or Rhino7 ? Im running it on Rhino7 now.

4. When is my optimization failing and why ?
