When my Ender 3 S1 (not plus) had bed leveling issues, the problem was caused by backlash on the Z axis. It’s important that the Z axis be just loose enough that downward motion is driven by gravity. If instead the Z screws have to “pull down” on the gantry, then the height will be too sloppy for ABL to make fine adjustments.

This requires patching Klipper, right? I don’t think I want to bother with maintaining a fork.
Though I designed a Z axis brace and plan to add some X/Y linear rails.
Android still doesn’t support DHCPv6 and will be left without a valid address.
RFC 7934 explains their reasoning, though it’s not exactly an ironclad argument.
Learning 3D modeling is slow process, but there are loads of free models online.
I learned how to use Fusion360 a couple months ago by asking GPT-4. The key is to start with an object you want that’s simple enough to describe, and ask lots of questions.

It is possible to smooth PLA using ethyl acetate, but I don’t know if that’s good enough for food safety, plus you have to remove the ethyl acetate itself.
PLA won’t survive in a dishwasher. PETG might, but there are no reasonable solvents for smoothing PETG.
Maybe it’d be best to print a mold in PLA, smooth with ethyl acetate, clean thoroughly, and then pour silicone into the mold.

the CR Touch needle is hitting the bed way earlier than the nozzle by maybe a few mm
Have you noticed that the crtouch has an extendable probe? The probe should be lower than the nozzle when homing or leveling (so the nozzle doesn’t hit the bed) and higher than the nozzle otherwise (so the probe doesn’t hit your prints.)
I found that auto bed leveling worked poorly on my Ender 3 S1, because the Z axis was not well-adjusted enough to make fine movements without binding. I reassembled all the Z axis stuff, making sure the eccentric nuts were just loose enough to not support any weight. You want almost all the gantry weight supported by the the Z axis screw(s), because downward motion is gravity-driven. If the Z screws have to “pull down” on the ganty, then the Z movement will be too sloppy for bed leveling to work.

Benchy was not designed to float. An STL file only defines the external geometry, but if you print it with default slicer settings, the density will be relatively constant throughout, and the resulting center of gravity is too high and too far forward to function as a boat.
In order to make it float, I put more mass at the bottom/rear and less at the top.
I haven’t had the courage to run executable code from P2P networks since the early 2000s. Even then it was probably a bad idea.
