Sorry, but your issue description is quite vague - or better - lets a lot of questions open.

Also the requested klippy.log is missing. Please attach that file it to your next post.

I'm having trouble uploading files, so I sent them via WebTransfer. You can download printer.cfg and klippy.log from the following link.

The problem is this: my printer works perfectly, the error occurs when I enable the following parameters in printer.cfg

[mcu rpi]  
serial: /tmp/klipper_host_mcu   
[adxl345]  
cs_pin: rpi:None  
spi_bus: spidev0.2

After restarting Klipper, the printer no longer connects to the host.

Hi @alfredcollie ,

Did you follow the instructions here to setup the Pi as a host MCU?

The error in your log is:

mcu 'rpi': Unable to open port: [Errno 2] No such file or directory: '/tmp/klipper_host_mcu'

This indicates something went wrong with the setup of the RPi microcontroller.

Please make sure you followed every step in the instructions correctly and verify that klipper_host_mcu shows up in ls /tmp/
