tool radius compensation left.

Hi

I'm trying to cut some pieces in my cnc router, I designed some pieces, in rhinoceros 4.0, after that i did a conversion of format file (.dxf) and then I used the dxf2gcode software to generate the appropriate code.

Well, after making the cut, I realized that the lenghts weren't accurate because of the tool diameter and because of the route followed (center), so I tried to change the g code and use G41 tool radius compensation left.

dxf2gcode had one option to use the tool radius compensation, but it doesn't work because it changes the shape of my figures, I don't know why.

So I start to edit the program by myself and I used the examples in the g code manual, but every time that I wanted to run in emc2, I got a lot of errors maybe because of the program structure.

Does somebody knows how to change from G40 to G41?

When I write G41 instead of G40, i got this error message:

"Length of cutter compensation entry move is not greater than the tool radius"

I do understand what it means, but after do some changes, the same happens again.

Seems to be that my program is reading some parameter, which is not in the program structure.

I attached the file, I need some idea please .

By the way, my T1 diameter is 1/8"

Ready! I was missing the entry mode.


Thanks a lot big john

why does my g42 cut the outside path instead of inside ?
if i use g41 it goes to the inside of my dim. i've read
www.linuxcnc.org/docview/html/gcode_tool...-Radius-Compensation
and can't understand dat . the lead-in looks like it is out of the pocket.(but then it doesn't show z)
