### Basic Information: Printer Model: None MCU / Printerboard: BTT SKR2 ERROR: `Unable to open config file /home/pi/printer.cfg` I’m using Octoprint and the printer is connecting through ‘tmp/printer’ port.

What did you use to install Klipper on OctoPrint. There are various possibilities. Most easy is using the OctoKlipperPi image. ---

I’ve moved past this issue, but now have a `mcu 'mcu': Unable to connect` error. I’m using a BTT SKR V2 REV B board with an STM32F429. Klippy.log [klippy.log - Pastebin.com](https://pastebin.com/hcyiqCzL) Here’s the output of `sudo dmesg` [sudo dmesg - Pastebin.com](https://pastebin.com/efCz3gQz) Printer.cfg [printer.cfg - Pastebin.com](https://pastebin.com/C172mekb) A business trip will now take me away from this for about a week. **Thank you for the help.** ---

Could you please upload your logs here? Pastebin is a pain to read. And I do not need another file server on my list. ---

Klipper is not flashed to the board. You need to follow the installation instructions. ---
