Flash Forge Creator Pro 2 not connecting

Trying to use a Pi with Falsh Forge Creator Pro 2. Got the FlashForge Plugin (0.2.6) installed and permissions fixed, had to disable the GPX plugin to do it. If I re-enable the GPX plugin I get an error.

What did you already try to solve it?

Disabled GPX

Have you tried running in safe mode?

No, disabling GPX allows me to connect.

Did running in safe mode solve the problem?

No, disabling GPX allows me to connect.

Additional information about your setup

OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible

Octoprint Version 1.5.3
GPX (2.6.8)
FlashForge Plugin (0.2.6)

I guess you messed something up in the plugins configuration.
Try to reset the config. If that doesn't work uninstall the plugin and remove the config here

tried reinstalling several times. Started over with fresh install and had the same problem. Just tried uninstalling and cleaning up and get a little different error now:
Changing monitoring state from "Offline" to "Opening serial connection"
Changing monitoring state from "Opening serial connection" to "Error: Connection error, see Terminal tab"
Changing monitoring state from "Error: Connection error, see Terminal tab" to "Offline (Error: Connection error, see Terminal tab)"

configured GPX and then got these errors again:
Changing monitoring state from "Offline" to "Opening serial connection"
Changing monitoring state from "Opening serial connection" to "Error: Connection error, see Terminal tab"
Changing monitoring state from "Error: Connection error, see Terminal tab" to "Offline (Error: Connection error, see Terminal tab)"

Maybe the is a bug in the plugin
I suggest you start over again and try it with the guide from @rswio

@PrintedWeezl I changed an option, as I mentioned and screenshotted in a different reply, that seems to have stopped the failed prints now :slight_smile:

Edit - oops, confused the post with another I'm on.

@Mark_Leeber I had to disable the GPX plugin, it wouldn't work with that on for me

Edit - oops, confused the post with another I'm on. I'm using the Flashforge plugin only

Thank you! I did send a test print with GPX disabled and while the bed homed and extruder heated nothing printed and the printer LCD said complete after 48 seconds but I have not jumped into the settings or gcode because I thought I had t have GPX. If you can share any of your settings that are not already in your post I would appreciate it. Thanks!

This is how I got it working:

Thanks! I have followed that a few times but GPX got in the way so I will see what happens today. Worst case I will start over a 3rd time and completely skip GPX. Thank you!
