I have had this printer for 3-4 years and it quit communicating via the USB connection. The software gives up saying it can't talk to the printer of it can't find the printer or some such error message. The physical connection is good in that I see the USB device in the printer, however the firmware or an upstream hardware component is failing to complete a handshake. I tried a new USB cable and two different computers but that didn't help. The printer still prints from the SD card so that's an option if I can figure out how to get a file on the SD card.

The Xyz slicer doesn't appear to give me an option to save a file to the sd card without a connection to the printer.

Any suggestions?
