Sooooooo, Here's a thing. Marlin 2.0.9.1 does not seem to support the BTT Octopus Pro. How about that.

The specific Pro I got doesn't even have the same processor as the Octopus and so I couldn't just use that.

Also there is no option to setup the Pro as the default envs in platformio.ini Or to select it from the drop down menu on the left column when clicking on the alien head. It just ain't there.

And so I will finish the wiring but I fear my quad Z coreXY project wont be able to run until after the next Marlin release. Which shouldn't be long, I am sure.
