Hi,
the default behavior of Mach4 as it ships is for the DRO to display the current applied jog speed, the number internal to Mach4.
Just because you edit the DRO DOES NOT Change the applied jog speed. If you want the DRO to display a different value then address the issue of changing
the applied jog speed, and the DRO will display it.
There are a number of DROs where if you manually edit the value that value will be 'pushed' onto that property within Mach, this is not one of them.
