Following error occurred when the collimator motor got stuck at the end of a raster scan moving from data collection back to sample alignment. This also prevents grid scan results from being displayed in the GUI.

This should be fixed now, however this error needed ti be shown in GUI. Hopefully this works. Parituclalry which motor got stuck. Now we use BEC this may need correcting but closing for now.
