Hello, I had recently updated to version 5.3.0. I noticed that when I would manually move to a waypoint it was always short of the actual waypoint by a couple few mm. The program ran fine so only when doing this manually. I decided to load an older version (5.1.2) to see if this problem would go away. Everything went as usual and the robot went to reboot and now it will not reboot at all. When powered on the logo shows and then I see a quick message that says "Debian GNU/Linux 8 ur 20185300385 login:_" That message is on screen for about 1 second and then the screen is just black. My original software version that came with the robot is 5.1.0. Any help on solving this would be GREATLY appreciated.
