mach3 now shows the Z-axis is no longer in bold but X and Y axis are still bold and working properly.
As you will see from picture "ScreenShot" the Z axis is no longer bold like X,Y, and 4.
This sounds pretty serious...
What do you mean the Z axis is no longer in bold? Where? A DRO? a label? a button? On the main screan? in motor tuning? What??? Where???
