Bricked My Machine #20

So I followed the instructions here and now have a bricked machine. I updated the items noted to be off such as file paths from previous Mainsail builds but no matter what Klipper will not connect to the MCU. The log is showing its trying to load a printer.cfg file that is empty, yet when I go into the UI or Putty, the file in that directory is normal. The below text is from the klippy-log, If I look at the file noted under "Args" that is the file I see in the web-ui, which is not the blank one. Any hints would be appreciated.

What do you have in /home/mike/printer_data/config/printer.cfg? The new klipper/moonraker uses a bit different paths see #19. So you have to use new ones (they are also in the updated readme).

## DO NOT EDIT THIS FILE, IT IS A TEMPLATE. THAT YOU NEED TO COPY
# Prusa MK3s Klipper Config

# The first thing you'll need to do is go through this file and comment out / uncomment 
# the files and/or settings you need.

# You'll be able to print just fine with this config as it is, but it is recommended
# that you follow these steps to properly calibrate your printer:

# 0) Sanity check and PID Tuning: https://www.klipper3d.org/Config_checks.html

That's indeed weird, did you install it via kiauh?

Yes I did use KIAUH. I am on a banana pi as well but figured it wouldn't matter once I got Armbian up

Can you do ps axf in the terminal. I want to verify that you are not running multiple instances of klipper.

@JesterIsDead Kiauh usually installs your printer configuration into a sub directory depending on what you named your printer. I.e ~/[printer_name]/ instead of just ~/

Can you run the following on your machine so I can verify this? I recently installed this after using Kiauh, which lead to me making my pull request here:

ls -la ~

2 replies

f1yn Mar 26, 2023

The reason I ask is because KIAUH might have setup Klipper to look in a different sub-directory, like ~/[your_printer]/printer_data/config/printer.cfg, which would mean that ~/printer_data/config/printer.cfg isn't loaded.

I'll check this out in a few hours. Going to format and start clean just to make sure I don't have random files hidden. I am nearly 100% sure this has to do with where the files are being saved. I'll restart and get back.

Fresh install of Armbian and Klipper.

1 reply

f1yn Mar 27, 2023

That's very clean. Have you installed Klipper on this machine yet or is it 100% organic fresh?

Also noticing that you're logged in as the root user. Worth also running ls /home to see if klipper was installed under a non-root user (which is likely best).

I'm working on it now, do you have discord by chance? That SS was likely right after my re-flash. I can resend now.

Actually oddly enough, I get different results from SSH and via direct.

Ok, clean Arbian, Klipper, Mainsail and Moonraker. Using the "make menuconfig" for Klipper I get the following and I am assuming settings at this point. I only have UART interface (serial technically) and some speed and baud to change. GPIO I'm guessing is not needed now.
