I've uninstalled and reinstalled it. No change. I've downloaded a CSV template, populated a few spools of data and uploaded it. It said it uploaded successfully, but I still have no spool tab, and there are no spools in the menu on the left column.
I found it. Thanks. I am new to Octoprint and didn't realize it put "Spools" into a tab drop-down menu near the top right. Found others I didnt know were there also.
