Maybe you're using light roasted coffee, which usually requires a higher quality grinder to extract properly. You could switch to something darker which for sure will reduce the acidity levels, or get a cheap quality hand grinder. I've had a 1zpresso for a while which does the job, but I finally got a good electric one too because it's only fun for a few weeks to grind by hand for espresso (it takes like 45 seconds)

I was curious so I tried to register with a Proton Pass liss which is @passmail.net and they also refuse those. I think they are afraid of services which allow to easily create multiple aliases, because people could create multiple accounts very easily (scammers maybe)? It's a dumb rationale because it's not much harder to create many Gmail accounts but that's the only reason I can think of.

Usually only one axis skips steps, especially since the MK4 has collision detection. A shift in both axes would rather indicate a steel sheet shift imo

Fantastic! Glad you got it in the end

Did you losen the idler tension screws? TPE requires that the tension is very very light otherwise it tends to buckle around the gear before entering the nozzle tube. Reducing retractions to a minimum is also always a good idea, as well as limiting the max flow rate.

Cargo dist! Here's a nice workflow you can use : https://blog.orhun.dev/automated-rust-releases/

A handful? Wow that's gotta be like 50% of the 50 series out there!

I prefer main simply because it faster to type. I propose main branches be renamed to "m"

It's like vim but with lsp support out of the box and the keybindings make sense

I'm afraid I can't recommend anything as I've never had issues with this, so I never really researched it. But if the banding frequency changes from print to print, then an issue with the Z axis is unlikely

What is driving the bed height? Lead screws? Check if they are straight and/or wobble around as they turn. Any imprecision in bed height due to mechanical issues with the Z axis would also translate into perimeter width variations.

Note that there are many security concerns with this, notably the fact that there is no input validation on the id path segment which means you can get the content of any file (e.g. http://localhost:3000/src%2Fmain.rs). It's also very easy to scrape the content of all the files because the IDs are easy to predict. When the server reboots, you will overwrite previously written files because the counter starts back at zero. Using a UUID would probably mostly solve both these issues.
