Hi I want to run this piece of code:

...........
I get the error message: "Arc to straight motion makes a corner the compensated tool can not fit in without gauging"
What does that mean and how to remove that message?

the tool cannot follow the path without gouging into the work ,, so either you have too large a tool for the curvature of the arc or the tool compensation in your tool table is too large for it to follow the path required

What it means is that there is a corner in the path which is too sharp for the tool to reach.
This is probably because one of your arcs is not tangent to the previous line.
(It looks to be the first G3, as that is the only one with both an I and J value.)

Hi
Thank you. I know what you mean, but don't know how to correct this. Could you please try to find out the correct arc parameters? Maybe a spiral entry would do it? Although I would not like to see the mill "dance" before making a simple rectangle profile.

I suspect you don't understand how cutter compensation works. Perhaps now is a good time to read
this chapter
on cutter compensation. While some controls will let you program a path that causes cutter gouging, LinuxCNC will not allow this.
