G41 and G42 Input path error

The example shows the simplest complete circular interpolation that a cnc machine can generate (G3I-50J0). Linuxcnc can not do it with G41, it loses a section of the circumference. Fanuc Generates complete interpolation with G41. Soon I will run this same code on a Fanuc controller so you can see the difference. Thank you very much

I wonder if this behavior was the same before the introduction of version 2.7 and the new trajectory planner?

In our Laboratory we tested the version 2.8.0 pre ...... the example is this version.

I tested it with 2.6.12 on a VM and the behavior was the same.

Well, I had issues also with this, and I understand that this is not a error, but I also understand that the "desired" toolpath is a full circle before the retract movement.
If you program a bit more of the circle after the full circle, then you will have the problem solved.
For me, it should not be considered a bug.

Since 1992 I have programmed CNC machines, A programmer should only worry about the path he wants to generate, and not be solving situations that the CNC is working on. Fanuc, Fagor, Siemens, have no problem, since 2008 I am reporting this very big mistake. A CNC should not miss traces of the path one wants to generate with or without G41-G42. Your comment is incorrect, I'm sorry. Thank you !!!!
