RE: OctoPrint bed visualizer gcode
Yeah I can see exactly why you'd pause now wrt the calibrations.
I doubt they'd ever introduce mesh topology to the public though...it highlights exactly how skewed and out of tolerance a lot of their parts actually are 😂
If you're going to include mesh stuff, especially for the C1, use the approach that Wejn has used here...ie, just probing the expansion joints.
Probing the expansion joints is a good idea. Not sure why Prusa didn't make it easier though to tram the bed. Relying on mesh leveling only is not good enough for tall parts (XZ and YZ skew).

What's ironic is I had a better bed level on my Ender 3 since it had both a PINDA probe and tramming adjustment.

The Prusa firmware is extremely forgiving and can compensate for a hell of a lot.
Combine that with the vast majority of people dont print tall stuff that needs very tight dimensional accuracy, so most of these skew and levelling issues just fly under the average users radar.

For the casual hobbyist printing a purge bin or whatever, completely agree. The bed leveling it perfectly fine. I ran into this very issue though printing long 250mm diagonal struts that would only fit if printed vertically then finding the screw holes were 1-2mm off. I had skew in all 3 axis that needed to be compensated for. Was a major PITA (and expensive since I burned through several rolls of PC Blend to get it right. I have this same issue on the H2D so it's not Prusa specific at all for sure.

Hmm, I wonder if you'll be able to compensate for this easily on the H2D. I think this is one of the places where Prusa is a clear win -- since everything is open source.
Then again, maybe you can compensate in slicer somehow? No "G29 P10" to get accurate Z offsets, though, I guess.

With my C1 it was down to mismatched lead screws, but at this price point i think thats just what you get.
With Prusa once I proved the issue, they ended up sending me 3 new z motors until I was happy so I really can’t complain.

For PrusaSlicer I've already written an add-in to fix XY skew. I've done it in 2 ways, post-process the g-code with a python script and in-line with a PrusaSlicer fork. Bambu Slicer is open source so it shouldn't be too hard to graft in. XZ and YZ are a bit harder the model itself would have to have the skew correction builtin (I think).

I was lucky in that regard.
