Because MeshCAM does all of the math internally to flip the model, any miscalculation will absolutely show up in the finished part.<br /><br />2) If you can, use the center of the part in the Y dimension as the program zero. Since this is the point that the stock is flipped around, using it as the program zero tends to eliminate some of the measurement problems in the Y direction. <br /><br />3) When combined with #2 above, two alignment pins will really help out a lot. I prefer to use precision shoulder screws that I get at McMaster Carr so that I can combine clamping and alignment in one part.<br /><br />If there is anything I can do to help out, let me know.<br /><br />-Robert (MeshCAM Developer)Roberthttp://www.grzsoftware.comnoreply@blogger.com
