Un-install the nebula smart kit

Ender Series Creality Ender-3 V3 KE/SE

How do I uninstall the nebula smart kit from my Ender 3 v3 se?
So I can use my printer with the original screen and settings as out of the box.

Regards

I guess you would detach the nebula. Attach the old screen. Write the screen and motherboard firmware to a formatted SD card. Insert and card into printer, power up and reflash. Not tried this yet. Might do it in the morning when I am not printing. Be handy to double check as I might be getting rid of the V3SE, time for an upgrade.

Thank you that’s what i meant.
Let us know if you succeeded.

My machine has a mechanical defect and they have asked me to return it for repairs.

I shall get on it in the morning. Might be replacing it with a Qidi X plus 3.

My MicroSD card isn’t playing ball so I can’t be sure.

Display firmware update：
1. Format the TF card on the computer side, and select 4096 for the allocation unit size.
2. Put the screen firmware folder “TJC_SET” into the TF card.
3. Turn off the printer and Insert the TF card into the card slot on the left side of the screen.
4. Reboot and wait for the update to finish.
5. After finishing the update, remove the TF card and delete the files inside.

Mainboard firmware update:

  1. Format the SD card on the computer side, and select 4096 for the allocation unit size.
  2. Put the firmware file “Ender-3 V3 SE_HWCR4NS200320C13_SWV1.0.6_GD303.bin” into the root directory of SD card.
  3. Turn off the printer and insert the SD card into the card slot on the motherboard.
  4. Reboot and wait for the update to finish.
  5. After finishing the update, remove the SD card from the motherboard slot and delete the bin file inside.

Thanks,
Is the first step, updating the screen firmware (TJC_SET) necessary?
Or is just updating the machine software enough?
I only replaced the screen for the Nebula screen?

I would say yes as my screen only sort of worked, the mainboard seemed to be working as the machine went through the full self test routine

Ok, it works.
Thanks

This still works. Had to go back because the nebula would not work in my V3 se. Thanks!
