Error setting up firmware retraction

[victorgilalejandria]

Hi, I'm seeing this error on Cura 5.4 when trying to setup firmware retraction.

I haven't been able to reproduce this on Cura 5.4. Does the error only appear when firmware retraction is enabled?

If you can, please provide more information about your system and upload or e-mail me the cura.log file after you see the error. On windows, it should be in "%USERPROFILE%\AppData\Roaming\cura\5.4". Thanks.
