It doesn't matter which file is selected to print. Even files that worked flawlessly before the update won't work either.

[michi6383]

Ok. I found a workaround. The problem is the "µ" in the filename. Ultiron_Fiberlogy_PETG_Ultiron_120µm_Angled_Foregrip.gcode

If you replace or remove the character it works fine.

[ontje]

Happens to me as well with non ascii filenames (german "Umlaut" for example)

Körper1.gcode does not work Korper1.gcode works (simply renamed the file, same content)

[drak42]

Glad I found this... Renaming file worked

[kolbenhans]

Jepp, same for me. Typical german Fusion 360 export of Bodies is Körper :D

There are two options to work with non-ASCII characters:

1. Use release version v0.10
2. Switch to Python 3

Is Klipper fully supported on Python 3 yet? According to the author of KIAUH it does not really sound like it: https://github.com/th33xitus/kiauh/issues/136#issuecomment-963480182

[mvoss96]

Can confirm this error still persists. I wanted to print a file containing the german letter "ä" and it crashed the printer

[Sineos]

As long as the issue is not tagged as "resolved" it will continue to exist :wink:

[CircuitGuy]

This issue got marked as a duplicate of #4959, but I think that's incorrect.

I have #4959 exactly. The same stack trace, etc. Which is not the stack trace of this issue.

Klipper seemingly won't print any files from the LCD with a space in it. For example Calibration Cube.gcode won't print, but Calibration_Cube.gcode will.

Strange. It has happened to me multiple times. Spaces in folder or filenames and non-ASCII characters (íöüóőúéáű in my case) are working for weeks/months and after a while, it stops working and I have to rename them. (Moonraker + Mainsail)

Today, for me this happend also again with an german "ü".

Everything up to date.

[webhive]

Same thing. All software is up to date.

[jperrin72]

got the issue today with a French word containing accentued characters (é)

[Piezoid]

I'll said it: this issue is waiting for python2 support to be removed.

If you want to keep a legacy python2 installation you need to stay on a stable release that support it. (v0.10)

While trying to have a look I realized that I can no longer easily install python2 on my dev machine and pi. This is probably the reason that no one will tackle this, even if the fix might be easy to implement.

I've been running klipper on python3 since April 2021 with minimal modifications. Since then, support has been added to klipper master in the wake of the v0.10 release. As of October 4, 2021, klipper runs without modification on python3. I believe it will be made official with the v0.11 release. MainsailOS is defaulting to Python3 since August 2021 and KIAUH added experimental support in v4. By now, it should be easy to use a python3 installation. I think that this should be recommended when following the development updates of klipper.

[DX94-Quas]

I got an error when using uppercase letters, got this on the log:

Traceback (most recent call last):
  File "~/klipper/klippy/extras/virtual_sdcard.py", line 178, in _load_file
    fname = files_by_lower[fname.lower()]

Unable to open file

the original name of the file is CE3_polea mod 5.gcode, I am using KIAUH to install, with python3

[mbravorus]

Same occurrence - sliced an STL from a file which had Chinese characters in the name, and this happens:

in fact, this is not the only place where things break - even after changing the gcode file name on the rPi host, it still refused to print, bailing out like this:

which from Fluidd looks like file is accepted and starts printing, but nothing is actually happening on the printer side

this is with

klipper v0.11.0-66-g4671cf2d fluidd v1.23.0 moonraker v0.7.1-806-ga154c5f

the system has fully functional python3, but the default one (and the one in klippy-env) is still python 2.7.16

[vladimir-poleh]

in fact, this is not the only place where things break - even after changing the gcode file name on the rPi host, it still refused to print

It seems that generated gcode contains Chinese characters in comments and it produces this error. You need to use Python 3 for the Klipper.

[Neko-vecter]

I think if the file name that contains the characters that not in ascii will cause this issue. Currently possible solutions is migration Klipper to python3.

How do I change from Klipper Python 2 to Klipper Python 3?

[Piezoid]

How do I change from Klipper Python 2 to Klipper Python 3?

@Murat65536 Since you're asking, the smoothest course of action for you would likely be reinstalling Klipper using KIAUH and select Python 3 when asked: ###### Select Python version:

The manual way is to recreate Klipper's python virtual environment. Something in the lines of:

cd
mv klippy-env klippy-env-py2
python3 -m venv klippy-env
./klippy-env/bin/pip install -r ./klipper/scripts/klippy-requirements.txt
sudo systemctl restart klipper

This relies on /etc/systemd/system/klipper.service invoking the new python interpreter from the environment ($HOME/klippy-env/bin/python) This is highly dependent on how Klipper was installed on your system.

@Piezoid I attempted to preform the actions but the error is still there. Even when there are no abnormal characters, the error does not go away. Is there anything that I can do?

I think it's solved after reinstalling Klipper using KIAUH and select Python 3.
