    Question Tool Diameter Offset

    Hello, I am relatively new to cnc and am using GRBLControl v 1.2.13b and am cutting out a shape but it is cutting center line therefore milling out some of the shape I want to cut out. My tool diameter is 3.75mm on the GRBLControl software its showing a 1.875mm Offset under the G54 button which I thought would solve the problem but it still cuts center line. I am not sure if I need to do something in the Gcode for it to work or if its supposed to work automatically.

    G54 is not the tool offset.
    I don't think that GRBL supports tool diameter compensation.

    As you can see, no G41/G42 support.

    That is something that you must do in your CAM software.

    Do you know G41 / G42 (cutter compensation at left (G41) or right (G42) side of path?

    Edit: I didn't see your post before I did send my question. Funny to have controller which knows G40 but not G41 / G42.
