Help me. I can't compensate the tool. G41/G42

Hi people. I'm really sorry for the question but I really don't understand where's my problem.
The simple ngc file is this.

M08 F1200 G40 G17 G21
G10 L1 P1 R3.125 Z1
T1 M6
G0 Z10
M03 s10000
G42
G1 Z-5
G1 X25.4 Y25.4

In order to compensate the tool, I tried several times in diferent ways but the answer is the same.
"Length of cutter compensation entry move is not greater than the tool radius"
I used G43 H1, and remove it and is the same.

The tool table:

Tool:1
Poc:1
z: 7
Diam:6.25
Comment: 1/4" fresa plana y recta

Coult you help me?
Thanks in advance

I believe you need to plunge inside the pocket you are trying to mill some distance greater than the tool radius. Try adding:
G1 X30 Y30
Just above the line containing G42.

This will give a little bit of a lead in to the cut, I am assuming it is a pocket so plunging inside the pocket then moving to the edge won't be a problem, if this is a problem at this location, you may need to modify the location to somewhere that works better.

I tried. Nothing change. ¿ ?

Good news!!! Looking in other ngc file with the same problem (a circle in this case) I discover the following- Is the position inside the file of G41/42 the problem (please compare both files). It is crazy but is easy to understand when you got it.
The right file is the following This file works fine.
