Strange smell after enabling performance mode on steppers
Oh wow. Yea that is scary. Your drivers will pull 1.6 amps but on 24V DC (or 48V if your running that). So that would equal to roughly 0.32 Amps at 120V (5x the voltage -> 1/5 of the amperage, ignoring losses from PSU) that each stepper needs.

Strange smell after enabling performance mode on steppers
Uff that sucks. Especially because the 10A fuse should have tripped long before 15A are reached. As far as I know the amperage your bed heater pulls is far higher than the stepper motors in performance mode. Are you on 100 or 230V? Could you post a picture of the melted Socket? Would be interesting were it failed as I have a similar one (on a 120W load, not my printer, but still).

Weird Artifacts / ripples due to Volumetric Flow Limit
DUMB ME While I was checking the sliced file for more Stats to give you, I noticed that somehow my Flow limiter changed back to 200 mm3/s. So it tried to print those arcs with around 44 mm3/s while the bondtech cht can do about 30-35. Havent checked exactly with this filament yet. I guess these ripples are how extrusion issues look on arcs when not printing in Vase mode (where you get the alternating extrusions) So solved - delete or keep for others 🙂

Klipper Screen not working.
I think mine also showed at least the boot screen on the pi on both HDMI ports, but I'm not at home atm to confirm. Did you check the pi with a different monitor? I would do that before I buy a new one. I got a Pi4 with 1GB ram which is enough for klipper

Klipper Screen not working.
over the web interface in the machine tab, you can update klipperscreen, restart it and reinstall it. However when the screen doesnt even show the bootscreen when the pi boots, then klipperscreen is not the problem. Either your screen is broken (check with another hdmi monitor for example), your cable or your pi. You can also check your BTT screen with another device, forexample your PC or something if it outputs anything.

Klipper Screen not working.
Does your screen show the console when the rpi is booting? if not its not klipperscreen... You can also put it in the other port, but you need to restart the pi as well.

I installed a btt smart filament sensor 2.0 but it gets triggered by the beginning purge of rat os.
Is the filament switch or runout triggered? Set the detection_length: 5 (or even higher) I noticed that the slack the filament has in the PTFE tube can be enough to trigger the Runout detector. Maybe your filament is "relaxed" in the ptfe tube, then when starting the print it gets pulled tight first, triggering the filament sensor. After you restart it pulls through the sensor as it is already "tight".

Wobble V-core 400
From my perspective there is no wobble in your leadscrew. One of mine wobbles significantly, like you can easily tell by eye. The middle wobbles at least a full mm and I dont get any Z-artifacts (thanks to the oldhams) Very bizarr, just to check, is your bed temperature consistent? CNCkitchen had a video on that, but I believe it only applies when using Bang-Bang instead of PID controll of the bed temp

Trash First Layers
Could be related to the new bed. I have one of those PEI / patterned PEO or whatever plates, and with the PEO plate I have to adjust my Z offset almost half a millimetre. Glad it's fixed 🙂

Wobble V-core 400
although... you showed in your first pictures that theres a difference between the point on the bed, so its probably not extrusion related

Wobble V-core 400
you could print the zylinder in different diameters, meaning a different amount is extruded per layer. that way the distance between the artifacts will change if its extrusion related ( so extruder gears, stepper shaft, etc are the culprit) or they will be the exact same if it is Z related (so leadscrews, constraints, bed, etc)

Trash First Layers
yes. But i wouldn't touch the config file myself. Just print a 1 layer thick rectangle and live adjust the Z value until it looks good. then remember to press "save config" after the print, which will save the offset to your config. Its very well explained here: https://docs.ratrig.com/commissioning-guides/v-core-3-1#z-offset

Wobble V-core 400
Thats weird, one of my Z lead screws is visibly wobbling a lot when turning, especially when looking at it like @VisualTech48 described. However I have 0 Z-banding or artifacts when printing. The RR couplers working quite well. Maybe one of your couplers is binding or the lead screw wobbling so much its hitting the cap head screws in the bed arms that hold the couplers

if that is the underside of the print, then your Z-offset is way too high as there is no squish. Couold you run the first layer test (i.e. the 1 layer thick square) and post some more clear pictures?

regular protrusions?
or rather blobbing / oozing of the nozzle. The blob on the nozzle that forms during travel moves is basically wiped off at the end of the travel move. If the positions stack up then you get these little towers or protrusions. I also had this problem with petg on another printer. Try increasing travel speed, tune your retractions settings, lower temps can also help

Curling issues on my V-Minion
make sure you enable "slow down for overhangs" in your slicer. I struggled with curling as well and by dramatically reducing the overhang speed it printed fine. Otherwise z-hop can help when your printer knocks off or hits parts. I use it for those articulated print in place models with lots of small parts

Newly built V-Core, ringing like crazy
measure the distance between the ripples, if it is 2mm it is most likely belt related. Either they are way to tight or too loose. https://ellis3dp.com/Print-Tuning-Guide/articles/troubleshooting/vfas.html https://ellis3dp.com/Print-Tuning-Guide/articles/troubleshooting/extrusion_patterns.html

surface stramgeness
I don't think its ghosting or ringing. Those only happen in the x-y direction and generally have several periodic artifacts. Like @outsider_dreams said it looks like it is following the contour of the inner features, that get "pushed" out onto the surface of the outer walls. Tuning your extrusion multiplier and pressure advance (again?) might also help, as the hole in the bow doesn't look perfect.
