I've got my brain sore thinking about this, so I'm a little foggy, but it seems the safest way to do this is to break the g-code program into a separate program for each tool change. If there where a way to make this look like one run, that would be better. Also, it would be nice to be able to use the same original part file for machines with repeatable tool holders or machines or tool holders that need a touch off for each change. The key to which type of change would be needed could be a setting in a configuration file or a special code in the tool table. A preprocessor could scan the g-code file for tool changes and create sub files of the commands between tools of the touch off variety. Then call the subfiles in sequence with a touch off macro between sub-runs. Checks would be needed to make sure the contexts don't change or are correct. Basically, automating what an operator would currently need to do by hand. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
