Bambu Lab Studio Printing Error After Firmware 01.06.03 Upgrade

Hi All,

I recently Updated my X1 Carbon Bambu lab to 01.06.03. The update was successful but when I tried to print a part from Bambu Lab Studio there was this error come up and check the error code on BAMBU database but it was not listed. Did anyone see this error before ?
Unknown-Error: 05000400-00020020-210831

After reading this, I updated the firmware and can print without problems.

After updating did you reboot and run through Device self test again. Try that.

I did reboot and tried Self test without any error. The problem seems to be that Bambu Studio cannot send file to the printer. I did try to log out of the account on the printer and Bambu Studio but no luck. Very strange. Raised a support ticket with Bambu hopefully they will get back to me soon

Strange behavior from a device after a firmware upgrade is often corrected by performing a reset to factory settings.

On the X1C, that is done on the settings page of the screen (the hex icon), “General” tab. Just touch “Restore to factory settings”, then set it up as you would a brand new printer, running the calibration routine, etc.

Thanks Ikraus,

Factory Reset resolve my issue.
