Hi MadTooler,
If the Status/DRO update has difficulty getting access to KFLOP for an extended period it gives up and displays the DRO's yellow as if disconnected. This shouldn't directly effect machine operation but is an indication something isn't normal like excessive USB congestion.
You might try our later code V4.34 including updating the KMotion/KFLOP USB Driver in Windows Device Manager. There have been some improvements.
Other FTDI USB Devices on the PC might be causing a conflict. Has anything been added recently?
Trajectory Planner Setting of Facet Angle less than 2 degrees may cause excessive motion vector data to be sent to KFLOP.
GCode data with an excessive number of tiny vectors, without a large enough Collinear Tolerance to allow the Trajectory Planner to combine/filter vectors, can also cause excessive communication to KFLOP.
Regards
