You may have cut off the most important part of the error chain, the real problem is likely to be near the bottom.

Yes, almost at the bottom:
AttributeError: Handler hal_button_pressed not found

So, in your .ui file there is a button that triggers the event "hal_button_pressed" and no handler for that event in the python.

Looking through the .ui file in a text editor:
cnc11.ui:34: <signal name="pressed" handler="hal_button_pressed" swapped="no"/>
cnc11.ui:49: <signal name="pressed" handler="hal_button_pressed" swapped="no"/>
cnc11.ui:93: <signal name="pressed" handler="hal_button_pressed" swapped="no"/>
cnc11.ui:108: <signal name="pressed" handler="hal_button_pressed" swapped="no"/>
cnc11.ui:123: <signal name="pressed" handler="hal_button_pressed" swapped="no"/>
Found 5 matches for "hal_button_pressed".

in the Python I see:
    def hal_button_pressed(self, widget, data=None):
        print ("on_button_press calllllllled")
        s.poll()

So you have written the handler, but in my editor the entire code body in the Python file appears to be triple-quoted (lines 15 and 120) and is highlighted in red. It may be that this is causing the whole handler file to be ignored.
