I just updated the CNCTW project here:
http://sourceforge.net/projects/cnctw/files/Machine%20Manager/Source/CNCTW.zip/download
It has the revised DynoMotion c# libs, support for feedhold
and
partial program running.
Was thinking about finishing off the Interpreter functionality(work offset editor, tool library, script assignment for things like homing...)before polishing some of the other features in hopes that some brave soul might try it out on a real machine
