Doesn't save config file. Just create empty printer.cfg file

[ZhenyaKa]

After any editing via this plugin and press Save button I got empty cfg file!

Me too

is there any log that can be extracted ??

I had the same today. Saving the file via plugin worked a few times but now its just empty.

I'm pretty sure this is the same bug as #23.

You can confirm by reviewing the OctoPrint log file which, by default, is here:

.octoprint/logs/octoprint.log

Look for something like this:

2019-02-16 02:20:51,628 - octoprint.server.api.settings - ERROR - Could not save settings for plugin OctoKlipper (0.2.5)
Traceback (most recent call last):

  File "/home/pi/OctoPrint/venv/local/lib/python2.7/site-packages/octoprint_klipper/__init__.py", line 109, in on_settings_save
    f.write(data["config"])
UnicodeEncodeError: 'ascii' codec can't encode character u'\xb0' in position 2486: ordinal not in range(128)

The character listed for you might be different. In my example above the u'\xb0' is the degree symbol.

The issue is with Unicode characters so I put a check in to see if they exist and then convert to a string before saving, if so.

This resolves #23 and #33.

I've not 'released' it yet but the code changes have been committed so you can see the fix - it's pretty simple - and you could edit your init.py with the change if you wanted.

Had the empty printer.cfg file problem today. Initially working fine then pasted some settings copied from web page and did a save. Empty file. Can’t seem even edit with nano now.
