My DROs are blinking..... x,y, and z blink, and when it does the position jumps to somewhere else....the position stays the same during the "blink" unless I move the coordinates. When I move the machines coordinates the blinking coordinates also move.....the cursor is jumping on the display when the blinking happens. I am unable to cut anything and my coordinates are always messed up and sometimes in the middle of a cut my the program just stops running on a line and the machine just starts to move in one direction....I think its because of this coordinate jumping blinking...
