Can't get MCU ID from Ender 3

General Discussion

Basic Information:

Printer Model: Ender 3
MCU / Printerboard: Not Sure?
klippy.log Not sure what this means.

Describe your issue:

I am a Klipper noob, I have never used it before.

I am trying to use a laptop to run Klipper (boo raspberry pi shortage). It is running the latest version of Linux Mint Xfce.

I have successfully downloaded the KIAUH and can navigate to the Mainsail interface through my web browser.

I am stuck on identifying the MCU connection that I have with my Ender 3. I have plugged the USB from the Ender 3 to my laptop and have tried running the run ls /dev/serial/by-id/ but keep getting errors. I have tried issuing this command both from the laptop itself, and also on a separate desktop using PuTTy to get into the laptop.

I believe this to be the last thing in my way to actually using Klipper for the first time. I’ve read guides and watched videos, I understand how I will have to update the config file and everything going forward, but as Mainsail cannot detect my printer until I inform it of the usb/serial id I cannot go further (if I am understanding this correctly).

Anything helps, again I am an absolute noob and may be missing something obvious. Thanks!

There are different Ender 3 versions and these need different approaches how to flash and different configs. Open the printer and identify its board.

Wow does life get in the way of things.

Thank you for your response. I have attached a picture of the board, but it says Creality V.4.2.7. I assume this answers your question as I did not see any other text on the board that seemed relevant (at least without unplugging things more)
