Better Grbl Support

#1

I enjoy Octoprint with my 3D printers and now I finished Dremel Cnc using GRBL .So why not installing this plugin!
It was working only first time and showing the state of all axis on UI.But suddenly no state is showing and no movement.When I plug with cnc shield without raspberry to my pc I can use axis and Its alive.But when I use with octopi and raspberry from web None of the axis is working.I reinstall Octoprint but It is still same.Is there any one having this issue ? Here is my screen
