I have Octoprint 1.5.2 and an Ender 3 Creality 1.1.6 (purchased used)
This is a fresh install of Octoprint and Octopi. I have rebooted already both devices.
I'm getting this error when I try to print an STL file
Could not upload the file. Make sure that it is a readable, valid file with one of these extensions: .g, .gco, .gcode
I've tried to Google the error but I'm running into a lack of solutions. I'm not too tech savy.
What am I missing? I thought STL files were supported for printing.
