What controls the stock orientation in the new G code Machine Simulator? Daniel Lyon November 04, 2013 18:33 I have my part programmed and I post the code and run it in the machine simulation. The stock seems in the wrong orientation in the machine and the simulation won't get past the first line. Why? Have more questions? Submit a request Comments Daniel Lyon November 04, 2013 18:44 The simulator won't get past the first line because the stock is likely colliding with a part of the machine. There is a setting to turn control how to handle collisions which is in the settings, warning settings menu. It seems to default to pause on collision. The SolidWorks co-ordinate system is the default orientation for the stock. The mill part setup does not control it. To adjust the orientation use a Solidworks co-ordinate system and in the machine (mill-in)>setup tab add it as the co-ordinate system. Once this is set the stock should be in the correct orientation in the machine..
