Hello!
when the circle start on G41 or G42, the tool position is tangent at two axis, and the full circle is break with it.
this problem have a solution ??
I see a reference in release notes to using G41/42 for Lathe Mode. There is also a release note on fixing full circle issues with G64 - Don't know enough about either to comment further.
