All: Newbie here...looking for guidance on printing from an unlocked USB drive. The .stl file is on the USB drive and I insert it into the FlashForge Adventurer 3 3D printer USB port. The printer does not recognize that a USB stick has been inserted. Going through the Build command on the printer menu indicates that USB is unavailable. Any ideas on why the printer thinks that USB is unavailable even though a USB stick is inserted?
