I've been printing from an SD card on a UM2+ successfully. We just got a new UM2+ Connect. All I see is a USB port. I don't want to hook this up to our network. I just want to print from the USB. (Why is there no SD card slot on this??!!) Anyway, when I use Cura to slice my file, save my file to the USB and put it in the 2+ Connect, the display reads that it's ready to print, but the Select From USB option is there, but grayed out. I've done the factory reset, turned it on, turned it off. Can anyone help? Thank you.
