To be clear, I'm not expecting 60 fps responsiveness, and there is a lot about it that I like better than Prusa.
But, when a fresh install with no plugins jerks when rotating an empty bed, it doesn't exactly inspire affection.
Seems to be par for the course, though, with complaints coming from all platforms and levels of hardware, so I guess it's the nature of the beast. And while it's great that some of its contributors chime in, the general attitude seems to be that it's something due to the user, or their hardware, not the software itself. That doesn't inspire confidence either.
However, the price is right, and ultimately, the results are what matters. There are always tools in tools in toolboxes that aren't going to be first one to be reached for, but they'll do the job.
