What is the problem?
Flashforge dreamer works perfectly with Octoprint ver 1.7.3. After successfully upgrading to 1.8.0 it wont connect anymore.
What did you already try to solve it?
I reinstalled ver 1.73 and it works, but then tried 1.80 again and it wont connect
Have you tried running in safe mode?
