I have recently started with a fresh version of octoprint installed on a RBi 3b+, I have installed the better grbl support, in the plugin's tab near the bottom it is missing the GRBL settings, saying signature : unknown.
does anyone have any suggestions?
as a side not I had it all working a couple days ago, but messed something up and had to do a fresh install of octopi, using the same settings but still not working.
