Describe your issue: Hello, so I’m a newbie to klipper and I have a problem that has been driving me up the wall.

so first i get this - Printer is not ready
The klippy host software is attempting to connect. Please
retry in a few moments.

then maybe a few minutes later i get this - mcu ‘mcu’: Unable to connect Once the underlying issue is corrected, use the “FIRMWARE_RESTART” command to reset the firmware, reload the config, and restart the host software. Error configuring printer

my MCU id is this - /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0

I have no idea why it’s rejecting my MCU I’ve been through 2 tutorials with no luck running off of a raspberry pi 4.

Likely your board is either:

• Not correctly flashed → Closely follow all information given on top of https://github.com/Klipper3d/klipper/blob/master/config/printer-creality-ender3-v2-2020.cfg and make sure that only the bin file is on your SD card
• Not correctly connected to your host, e.g. bad USB cable etc

hello i feel stupid on how easy the solution was i was changing the .bin file to firmware but i tried it again but just leaving it as klipper.bin and it worked.
