This is my first post so I am hopeful for some help.  I just encountered a problem with Mach 3 interface with my Precision Matthews PM 30 mill.  When I highlight the S DRO and type in any speed, the numbers appear in the DRO box but as soon as I hit the "enter" key the number changes to a -1 value. I haven't intentionally changed any configuration settings.  Any help would be appreciated.

Thanks

Try return instead of enter...
