So i have finally built my machine. now having a little trouble when getting a new arm made up i will explain so i have drawn up my design in solid works and saved it as a .igs file opened the file in bobcad sorted all the machining out in bobcad but when profiling the arm every pass it moves away by a few mill have attached a photo it is quite hard to explain at first i thought it might be the drawing so redrawn the whole thing but same thing happened don't have a clue been scratching my head past few days trying to figure it out will appreciate any help thanks
