@miklschmidt any ideas?

yeah same deal as usual. chelper not compiled, is my guess. I have no idea why it's so random. @shifubrams Please try this: To fix it you can do:

ssh [email protected]
rm -f ~/klipper/klippy/chelper/c_helpers.so
sudo systemctl restart klipper

ssh [email protected]
rm -f ~/klipper/klippy/chelper/c_helpers.so
sudo systemctl restart klipper

Then wait 5-10 minutes and try going through the configurator again.

Will do right now Not working. Should I reboot the pi ? I know it's not the motherboard as It works when using the SD card

What do you mean it works when using the SD card? Do you get through the configurator if you choose "Flash via SD card"?

shifubramsOP•17mo ago

Yes if I choose the flash via SD card. I go through it ... Generate the bin, then download the bin rename it, paste it to the card and boot the card on it. And then ... Tadaaaa working. But DFU mode not

That's odd indeed You may need to remove the boot jumper and press the reset button after it's detected when flashing via DFU mode
