TestShapes-OperationOvercut0.1 shows the problem, when the operation overcut is not zero and the start point is specified to be overcut 0, the leadin is not tangent.
TestShapes-OperationOvercut0 shows the leadin actually tangent to the cutpath, regardless of the start point setting.

Start point in question is the outside path in the lower right corner.

My guess is its a rounding error somewhere. I dont know what else could cause that. I could be totally wrong though.

That is deliberate. A tangent leadin makes more sense than a perpendicular one when you are on an outside corner with no overcut. With a perpendicular leadin the machine has to make a sharp change in direction at the end of the lead, which slows down cutting and can affect cut quality. Instead it uses a tangent as this takes up no more space and it should result in a better cut. Does this cause a problem for you?

I dont think we are talking about the same thing here... In the TestShapes-OperationOvercut0.1 file, the leadin is not tangent to the path. That is the problem.

In the TestShapes-OperationOvercut0 file, the leadin is tangent to the path as it should be.

If i change the leadin to perpendicular, the path is tangent, but it has the step offset and the slow down you are talking about.

Is it showing up differently on your system?

I now see what you mean. Yes, that is a bug and it will be fixed in the next release.

Ok, thanks Les! Sorry for the confusion.
