I think the numbers we have now are reasonable defaults, but i wouldn't be opposed to a patch that allows users to override it from the ini file. I think you're currently talking about changing just the DRO, what about the other 3 or 4 sets of numbers (DTG, G5x offset, G92 offset, etc)? With 6 sig-figs on all of these, would we run out of screen real estate? With the "big dro font" option in Axis, on low-res screens, maybe. -- Sebastian Kuzminsky ------------------------------------------------------------------------------ _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
