Is G81 no longer supported?
I use the Octoprint plugin called 'Prusa Leveling Guide' by Scott Rini to level my MKS3S+ bed (I have the Nylock mod). I just upgraded the machine to MK3.5 with the kit (keeping the Nylock mod), and now the plugin doesn't work anymore. Looks like it issues a G80 to do mesh leveling and then G81 to get the results. I tried sending G80 in the terminal and the G81 and while the leveling finished correctly, G81 did not send the offset matrix. In fact I got a 'unknown command'. Is this expected?

I need to try again, but the one time I did I couldn't even get G80 to work. It made a horrible grinding noise so I hit the reset button. I had the silicone mod before and it worked great. No problems with the clips I put in from the kit, I was just wanting to see how level it was.

Honnestly. Got the nylon lock and the Plugin with octoprint on my mk3.
I remove it when upgrading to mk3.5 to ensure i got the designed product at first.
First layer are perfect. The mode is not really needee anymore.
RE: Is G81 no longer supported?
Yeah, I ended up removing the Nylock mod and using the new brackets. I did have to install BedVisualizer to make sure that it was level. I had to manually adjust one of the two Z-motors since the bed wasn't level left to right.... but yeah, first layers are perfect now.

Agreed, these expansion joints do the trick perfectly.

How are they supposed to work exactly? I've never seen it explained.

I had the silicone tube mod on my MK3S+ and I went with the expansion joints for the same reason as you. You're using Octoprint to get the bed level measurements right? I'm not using Octo right now even though I had it on the MK3S.
Any other way to get the necessary info to level the bed besides pronterface and G80/G81?
RE: Is G81 no longer supported?
Not entirely sure but I fitted them and my prints are coming out just fine. I haven't done a full bed level test print but if anything the printer feels more robust.
As for what they do I assume they expand with heat and keep a uniform expansion over the whole thing? Then the ABL takes over the rest. Either way it prints good.
RE: Is G81 no longer supported?
Has anyone figured out how to get the bed leveling data from the MK3.5? As OP mentioned, G81 no longer appears to be supported. The new heated bed brackets are not working nearly as well as the nylock mod I had in place before the 3.5 upgrade.
