Lathe simple GCode / compensation

Hello. I have been running Linuxcnc lathe for a nice period of time and normally I can get things running as they are supposed to.
Currently I want to machine a very simple shape, but due to the compensation it is not letting me to.

The following code fails due to the compensation (the common gauge error), and I am not seeing correctly how to solve it.
Tool is outside machining, radius 0.4, tooltip direction 2 (linuxcnc tool tip direction)
Taking the compensation out, the code is accepted.


The output should be the outside of the picture attached.
I understand the problem, that is related with the intersection of the two lines that create a less than 90 degrees on the top, but at the same time is not clear to me to solve it (and still use the compensation ON that will be necessary).
Any ideas?
Thank you

The error is more likely to be the inside corner not the outside corner. The error probably says near line xx and it is usually the next line. The inside corner can not be less than 90 with cutter comp as it can not reach the end of the vertical line before gouging into the next line. Try changing your code to put an arc or a short corner that can be reached by the tool.

Thank you,
Will look into it and post the results.

Correct, I added a radius a little larger than the tool radius and the code is now accepted, and most important, it makes sense.
