Core firmware update

The touchscreen might require you to update the core touchscreen firmware on some occasions.

This document will guide you through the update process.

This process will require a micro SD card with a capacity under 8GB (larger micro SD cards might not work for this purpose).

A failed flash of these files could brick your touchscreen. Be very careful not cutting power from the printer during the flashing procedure!

Start by formatting your micro SD card. Select FAT32 for the file system and 4096 bytes sector size (these parameters are strictly required for the procedure to work).
Create a folder at the root of your micro SD card and name it DWIN_SET.
Copy the two .BIN files you previously downloaded into the DWIN_SET folder.
Unmount and unplug your micro SD card.

Turn off and unplug your printer (both power and USB).
You will need to access the micro SD slot on the back of the touchscreen (not the one that could be on your mainboard). If necessary, open the printer to be able to access this slot.
Insert the micro SD card into the slot.
Plug the printer's power cable back (and only the power cable) and turn the printer on.
After a few second, the screen's background will turn blue and the flashing procedure will begin.
Do not cut power to the printer while the flashing procedure is running!
When the procedure ends, you will be back on the page with a blue background. There will be an END message at the top and you'll be presented with a summary of what was flashed.
At this point, you can turn your printer back off, remove the micro SD card from the touchscreen and reassemble your printer if you had to disassemble it previously.
