It has to have the card even for USB printing. The XYZ machines do not print in stream mode. They upload the entire print to the onboard sdcard before they print. That way you can disconnect the computer at any time without loosing the print.

If you have the contents of the card saved I would suggest getting a new card and copying the contents over then installing the new card in the printer.

Check If keypad disconnection from mainboard helps. Sometimes key stuck and forced enter bootload mode.

To eliminate this as a possible problem I tried again using a stock install of Windows.  After I installed XYZWare I launched the software after connecting the printer with it in bootloader mode.  XYZWare immediately indicated it would update the printer and the update dialog appeared.  The process took a few minutes and ended with a message stating the process completed successfully.  The printer was still in bootloader mode so I powered it off and on.  The printer still didn’t boot.

In bootloader mode the update dialog identified the printer model and version as well as the serial number. The MacOS software uses a command click on the update button to display the open dialog for selecting a bin file containing firmware.  On Windows I’ve tried a bunch of combinations.  I’ve tried shift click, control click, alt click, etc.  None displays the dialog.  Does anyone know how to make this appear on Windows? 

I’ve tried updating this printer unsuccessfully two more times.  Both times the process completed successfully but the printer still wouldn’t boot.

This printer may have a hardware problem.

Post #8 and it doesn't hurt to read other relevant post.

if your firmware version is lower than 2.2.6, the above method should work. Otherwise, I don't know what will happen since the cause of firmware corruption is unknown.

I believe the firmware is corrupted.

I've been able to get the printer into Bootloader mode by holding down the up and down arrows while powering on.   

Can anyone tell me how to flash the firmware, if it's possible, while in bootloader mode?   XYZware doesn't display any info about the printer (serial number, etc) while in bootloader mode, but the "update firmware" button is available.   Unfortunately, it doesn't work due to timeout errors.

It's possible this might be a problem with my laptop.   I have a USBSerial driver I use with hardware to connect to the console port on network hardware we have at work.   I'm not sure if this driver is interfering with XYZware.   

Any ideas would be appreciated.

Thanks!
Bob
