Hi,

These can be difficult to diagnose remotely (me being remote):

Serial communications can be a challenge as well and cause issues.

Check the _console folder_ for logs in the same folder as _preferences.txt_ (down at bottom):

It logs the console output to the best of my knowledge.

Keep at it!
