Configure Fluid to use COM port when updating Klipper

Frontends Mainsail
1

I installed Klipper on the CR-10-Smart over three years ago. I had to replace the SD card in the Pi last week and had to update everything to the new Raspberry Pi Trixie version, it was on Bullseye. So I reinstalled everything and pulled updated Kiauh and the accessories it manages. I built the new updated klipper firmware, but Fluidd is syaing it cannot find the MCU. When the Pi booted, it assigned /dev/ACM0 to the CR-10 Smart. How do I configure using Kiauh. The documentation for using and Installing Kiauh is not very clear on how to reconfigure after updating to a newer version of the OS. Klipper was already running fine but hasn’t been updated for three years.

Thanks in Advance

Hi @oliverhbailey ,

KIAUH only installs/updates Klipper. The configuration happens inside Klipper itself. In Fluidd you can go to the config editor (on the left it looks like the {…}) then open your printer.cfg. You’ll probably need to paste in a config for your printer (or use your old one if you backed it up). Under the [mcu] section you can set the serial port to /dev/ttyACM0
