I’ve just added my Robo printer to RoboCloud but it is saying “offline” instead of “idle.”

When you connect a printer to RoboCloud, it takes a couple minutes for it to show up as online (aka idle). Go ahead and start uploading and slicing your model. By the time you are ready to send your model to your printer, your printer should have changed its status to idle and be ready to print! If it isn’t ready yet, wait another minute or so for it to show up.
