    hey guyz. i used the plunge tool perfectly untill i wanted to do a larger plunge diameter.
    i set the plunge at 100% depth and 16mm diameter. when i tested the code out on the machine it started to make a bigger hole than my machine could handle. here is the output gcode.

    nothing wrong with that Gcode at all.
    for example the last line
    G03 X180.0000 Y18.5000 I0.0 J6.5000
    says go to X180.0000 Y18.5000 and do a circle of 6.5mm radius. 6.5 + 1.5 (half the bit) is 8, which will give you a 16mm diam circle.

    "bigger than your machine can handle" I interpret to mean that your machine controller ignored the G21 (set metric mm mode) and is considering the numbers as inches. that would make some big circles!
