Consistent hotend temperature offset
The story is, I had a running printer with RatOS 1, but the part cooling fan was not properly recognized. Since it went super well on the VC4.0 I bought, I figured that I could update the printer. I wired things exactly the same, and installed RatOS 2.
I'm not saying it must be that, but I'd like to know if it could.
I'm going to test everything we've talked about tomorrow anyway. It's just to get a grasp on the machine.

I tried with 2 different ones, the one from rapido, and the one for mosquito. Each time reading the package and double checking on the configurator.

Can I have your honest opinion? Am I fixating about the potential soft issue? Or RPI?

Thanks for the tip, I'll add this to the list of things to try. Since I'm not comfortable at all with electronics, I might do it last...
I'll try it tomorrow. Thanks for your help, I'm happy not to be alone on this mess hahaha.

can it be the USB cable? because the EBB board is new, and the wires are new too
I was also thinking that some common ground was not working, maybe between the octopus and RPI

If that does not work, I'll push the RatOS v1

V3.1 Catastrophic failure - massive layer shifts
I think it's unitless. It's the Power Spectral Density. I looked at this thanks to this comment https://discord.com/channels/582187371529764864/1344387843581280328/1345764604965425244.

V3.1 Catastrophic failure - massive layer shifts
I thought that the ideal belt tension should be betweem 500 000 and 800 000 to work properly.

Consistent hotend temperature offset
The EBB42 is! I changed the USB cable as well (seems to easily break). Could it be a software issue, though? I could re-install V1 to try...
I can re-crimp all cable for extra-measure, but from XP, bad crimping leads to the target C, not the target B :/

V3.1 Catastrophic failure - massive layer shifts
I re-tightened them after the incident, but I'll loosen more. Thanks.
I've been having successes since I tweaked the filament temperatures. I wouldn't have expected this to cause that to be honest!
And the temp shift is another mystery on its own.
I appreciate the help @blacksmithforlife , thanks a lot 😉
