Hello there! I am trying to modify klipper firmware to download into my 3D printer CR-6 SE by inserting my SD card, and realize that the printer is not successfully written by my modified klipper every time. Does anyone know what the problem is? SD card has been already formatted as FAT 32 and 4096 type and it did some time. Thanks!
Hello @Thomas_R
maybe that’s the reason?
Thanks for your reply! Just got that a new firmware name has been updated when it is downloaded into the printer.
‘not successfully written by my modified klipper every time’
It’s never successfully written? OR is it sometimes successfully written, just not every time? Those are two different problems. Your description was not absolutely clear.
If it’s the former, seems like the error may lay in the code being installed or the installer code itself. If the latter, a flakey SD might be an issue. Maybe re-imaging a new SD card would be a good first step if you have no other error codes or output to go by. If that fails to change anything, then as was mentioned, maybe back out your changes to the klipper code, and try installing a very generic version first, to eliminate anything you may have introduced inadvertently. Those seem like a good way to approach the issue.
Good Luck!

@Thomas_R I have a CR-6 SE and learned that the beep that happens on firmware completion does not always play. Furthermore if you are anticipating the LCD to work after flashing the main board it will not. you will need to
1.plug in the sd card with the correct firmware based on the klipper github configs.
2. Wait 5 minutes to be safe
3. turn off the printer, remove the sd card. Then plugin your klipper host via usb(commonly a raspberry pi3 or 4)
4. turn on the printer then the pi
5. now navigate to the mainsail/fluid ip address in a web browser to configure the printer.cfg file
