I think it is worth looking into what homing can do for you. One thing that comes to mind, the soft limits are based on your machine origin. When the origin is set and the axis limits in your .ini file are set relative to this origin, if something unexpected happens which causes a travel beyond the physical axis limit, the axis will be stopped at the soft limit. At this limit, you can conveniently back off the limit and fix the problem. If you hit a firm limit (hardware switch), you need to override the limit error alarm. If you hit a hard limit (metal to metal), it could be bad for your machine. AXIS will show you the soft limit space relative to your part, so you will be much more likely to catch a problem before you run the part. If you don't have limit switches, but do have dials, you can set home by making marks on your axes. Then at power up you jog the axes until the marks line up, slowly jog the dials to zero, then set home for each axis. You will then have the proper soft limits, will be able to reuse previous setups and be closer to being a real certifiable CNC machinist. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
