I had Better GRBL support previously installed and functioning, I decided to do a fresh install on octoprint on my pi 3B+, now after the fresh install in the better GRBL app in the settings under GRBL settings it shows Signature: unknown. I have tried uninstalling it, i even tried installing an older version and still no resolve. i have attached a screen shot showing the no signature. Thanks in advance image

It appears your machine is not connected, or has never connected. The Grbl Settings ($$) results should be listed below the Signature (Id / Value / Description) too. While connected you have the ability to modify them as well.

Somewhere around v2.0.0 I changed the way I identify the Grbl Signature. Previously I just scraped the Grbl Info text that shows up with a soft reset but I later changed this to use the results of $I which I query on obtaining a successful connection to the machine.

Prior method:

Send: \x18
Recv: 
Recv: Grbl 1.1h ['$' for help]
Recv: [MSG:'$H'|'$X' to unlock]

Current method (on connection):

Send: $I
Recv: [VER:1.1h.20201218:]
Recv: [OPT:V,35,254]

If after connecting to your machine these fields (including the actual Grbl Settings that should be shown below) do not populate please execute the following procedure:

  1. Disconnect your machine via the Octoprint Connection sidebar Disconnect button if it is connected.
  2. Clear the Terminal buffer (Clear All) in the Terminal tab
  3. Connect your machine via the Octoprint Conection sidebar Connect button
  4. Copy all content within the Terminal tab and provide it to me here
