If you look at the sketch, there must have been a crash at X-2 Y-2 with the G0 Z-10 move, without cutter compensation. There was no report about. Probably touch off was done with the tool to sides of the block. T without M6 only prepares tool.
Since cutter compensation in linuxcnc is kind of ¿?¿ ,it`s good advice to read this part of the manual.

Thanks to all your comments. I thought it´s easier to run a simple program. I will check all suggestions in the next days.
Merry Christmas.

Here's an attached png to clarify what I posted earlier.
The red is your file with no tool loaded and no D in the G41 line. You need one or the other for linuxcnc to read the tool table.
The white is a compensated path with a lead-in, notice how it rolls around corners.
It's not hard programming if you follow the rules.
Merry Christmas to you as well.

I changed line 5 to G41 D10 and did not use the tool table. Homed the machine and touched left lower corner of the workpiece with G54. Then i loaded the program below with error "Length of cutter compensation entry move is not greater than the tool radius".
To have no problem with tool cutter entry i added line 4 to be far away from the corner. But this does not help.
The error comes right after loading the program, in the status line bottom i have no tool loaded. And G54 DRO view does not change the values when i jog around the axis by keyboard.

Try an XY move after the G41.

Hi Mane
It's as Andy said, a minor change gets rid of the error.
The difference between G61 and G64 it may a good read. My apologies if you're already aware of those codes.
While the rest of the household was watching the Die Hard marathon I did a little blog post on cutter comp.
I am not an expert on the topic but maybe there's something useful there.
