That is kind of what I was gathering from my lack of finding anything.

I did see somebody complaining that Octoprint prints kept failing, they surmised because the board wasn't fast enough to keep up. That was from 2018 though.

Some places list a QQ-S Pro Upgraded, but there is no information on what has been upgraded. I was hoping to find something that said 'this is what was upgraded, this is how you do it on your base model'.

While looking for information, I did run across this post:

That just makes me want to buy a printer even more.
