Can't connect to FlashForge Creator Pro

I've just reinstalled octoprint on my raspberry pi (using octopi) and then restored my settings through the backup/restore menu. It restored all of my plugins and the printer profile but for some reason, I can't connect to my printer anymore. I have my baud rate set to 115200 and the serial port set to /dev/ttyprintk which is what I used last time. At first it would give a permission error when accessing that port which I solved by changing the permissions through ssh.

Here is the log when trying to connect:

Connecting to: /dev/ttyprintk

There was a timeout while trying to connect to the printer

Do you have the GPX plugin installed?

Looks like it didn't get reinstalled when I did the restore. Installing it and configuring it for replicator dual fixed the issue. Thanks! :slight_smile:
