If the "CV Distance Tolerance" checkbox is checked (turned on) the machine is in exact stop mode, if you uncheck it (turn it off) its in continuous velocity mode. So its backwards. This is in version R3.041 and R3.042.008. I'm not sure when this happened but it has not always been this way and I have made no other changes to either of my mills except upgrading Mach. Please correct this.
