i am making a part and have trouble getting it to cut the part out with bobcad 17, i created the part and when i go to create the gcode it doesn't machine it properly, i am also have a problem with island surfacing. the material is .375 plastic rod. i have it mounted on an 3c collet chuck bolted to my mill table. the endmill is .119 flat endmill. maybe someone could try it out, i am machining it on my homier mini mill and using maxnc software. thanks mike
