Moved to the get help topic, since that fits this far better.
When you press the items on the control tab, the commands should be sent to the printer. Can you try switching back to the terminal tab, and typing something like G28 X Y (home), which would be the same as pressing the home button in control. Then we can see if it is an issue with the printer or OctoPrint etc.
I had this problem on my CR-10S Pro V2. Removing the SD card fixed it. I really don't understand that since control works fine from the PC with Cura or Repetier. I DID block 5v on the USB cable to block back power from the printer to the Pi but that didn't fix it. Removing the SD card did.
Very weird.
