dxf2gcode and tool diameter offsets was created by steeley
I been trying to figure out how to compensate for the tool diameter in dxf2gcode - changing the start radius doesn't appear
to do anything. Can I just ignore this and set it in emc2?(g41 maybe?)

Probably not, as you need to know which side of the line you are cutting to use G41, and that might be hard to figure out from the G-code.Can I just ignore this and set it in emc2?(g41 maybe?)

Pretty much given up with this, I thought I had something working but all I get in emc2 is the error " length of cutter compensation entry move is not greater than the tool tool radius"

After you "turn on" cutter compensation you have to move a distance longer than the cutter diameter for the currently loaded too. This is the move that positions the cutter to one side of the line.

Thanks for the info guys..
I do understand this, and for some reason its probably going wrong in dxf2gcode.
For now I can just add half the tool width to the dimensions in the CAD drawing.

That is what I often do, draw a line in the CAD drawing parallel to the line I want to cut offset by 1/2 the tool diameter when the tool size is known.
