Automatic deletion of Printer.cfg

General Discussion
1

Issue Explanation:

I am experiencing an issue where my printer.cfg file is being reset when I update Klipper. I do not want this to happen. Will turning off the write permissions for the printer.cfg file solve this problem?

The printer.cfg file is being deleted, but the old one is kept. I do not want to keep doing this manually. If anyone knowledgeable could help with this, I would really appreciate it. Thank you.

Hello @rkutun !

How do you update Klipper?

3

Hello @EddyMI3D !

In the settings section, updates can be performed through the update option. Additionally, in the Mainsail interface, there is also an update option available in the Machine menu. Updates can be done from there as well.

4

This must be a (strange) misconfiguration or local issue on your side.

  1. I’m not aware of any similar reports
  2. If this was a systematic problem, this place would be full of such reports

Please provide a klippy.log as initially requested anyway

The screenshot here shows the records of the printer.cfg file. I want to prevent these records from being created and ensure that the contents of the printer.cfg file are not deleted.

When the machine shuts down while the printer.cfg file is open, its contents are deleted, and the file is also cleared when there is an update to Klipper. As a result, I encounter the error shown in the second image I uploaded. I need to rewrite the contents of the printer.cfg file to fix this. Is there a way to resolve this issue?

7

These are backups of the printer.cfg that are created by Klipper automatically.

And again:

@Sineos
What should I check in the klippy.log file? Can you help me?

Simply attach the full and unmodified klippy.log

12

You just should attach the klippy.log and not post some lines out of it.
If you want help you should work together with the helping people here!
So create a new post and just drag’n’drop the klippy.log to it.
If this log is too big you can compress it with a common zip tool.

@Sineos @LifeOfBrian

Could you specify exactly which directory the file is located in?

“Could you check my klippy.log file?”

Generally the paths and locations seem to be according to the expectation in your setup.
There are strange error messages in the log that might point to a permission issue on Linux OS level.

Please show the output of the commands:

  • ls -al /home/pi/printer_data
  • ls -al /home/pi/printer_data/config

Use the code formatting tags here </> to copy and paste the output.

This is strange, indeed. The permissions are looking correct.
Please provide a step by step instruction how to reproduce the issue, e.g.

  1. Do this
  2. Open that
  3. Turn off A
  4.

One observation, & one suggestion.
I see this file printer_autosave.cfg in your file listing
Found some information about that on Reddit - Dive into anything
That would have resulted from an interrupted file backup after a SAVE_CONFIG.

Some more Ive read is that, It may indicate sdcard maybe starting to flake out


The Suggestion I’ve read is to “hide the backup files” it can present a better view into your config folder.

If you click the gear icon in the Config Files section, you can tic the checkbox to "hide backup files". Then just let it handle the backup files on its own, and you don't have to see any of the copies it makes.

I’m not doubting your claim its erasing the config file, but its generally not touched unless your doing a save config.

If you happen to be running bed meshing and want to avoid the save_config prompt, it can be overidden in the UI
