SKR-Pico VS klipper

That's a question outside my scope of knowledge. I can tell you that it's a microcontroller used to control a 3D printer. There are 5 NEMA 17 stepper motors, a hot end for melting and extruding the filament (around 200 Celsius) and the build plate is heated (60 - 70 Celsius). Here is a link to the manufacturer's GitHub if you're interested in checking it out: https://github.com/bigtreetech/SKR-Pico/tree/master/Hardware

https://github.com/bigtreetech/SKR-Pico/blob/master/Klipper/Images/wiring_uart.png they have the wires backwards.... I see a lot of things like that. That's just different from what is shipped. Forget about the fact that the wire is plugged in backwards, what is shipped to the customer is two reds, a black, one green and one yellow. There is no blue. That's what I feel like right now: I'm following instructions/directions with a blue wire and there was no blue wire in the box...

I have a sonic pad that I have working on one printer that uses an aquila motherboard so I know the sonic pad works. I just got an SKR Pico and installed it in a different printer. I flashed the firmware and with klipper-USB.uf2 from https://github.com/bigtreetech/SKR-Pico/blob/master/Klipper/README.md

Did you go through the steps here for building the firmware? https://github.com/bigtreetech/SKR-Pico/blob/master/Klipper/README.md

The SKR-Pico is very well-documented on the BigTreeTech github page

I'm looking around for specs on maximum power/current draw for the SKR Pico run at 24V. Unfortunately, the documentation is pretty slim (link to BTT Github for SKR Pico), only mentioning 0.8A draw on the stepper drivers without additional cooling in the user manual. I'm concerned that the board may not be capable of pulling enough power for my Gulf Coast Robotics heated bed, which lists a rating of 250W @ 24V (nearly 10.5A). I also have a Mosquito hot end, which lists a 50W heater, plus the motors drawing a total of over 40W, so I'm likely pulling over 350W, with running my SKR Pico, Pi Zero 2W, and touchscreen off the same PSU. (Pi and touchscreen were powered via UART cable off the Pico.)

Switching over your config should be pretty straightforward, you'll just be changing the [mcu] section (obviously) and all the pin assignments. BigTreeTech boards are really well-documented and both the SKR-Mini and the SKR-Pico include excellent pinouts and schematics as well as sample Klipper configs on their github pages.

Has anyone powered that board (Le Potato AML-S905X-CC-V1.0-A) by applying +5vdc to GPIO pins #2 and #4 (and ground to pin #6) as described by BTT here or page 10 of the BTT Octopus manual here?

There is _a lot_ wrong with Marlin. It is a complex codebase, full with ancient artefacts, litterred with preprocessor ifdefs every 2-3 lines of code, dynamic includes in the middle of CPP files, etc[1]. It's about as unreadable as C++ code gets--well, I guess it's not template metaprogramming.

Klipper by contrast is a breeze to read through[2].

I am very grateful for Marlin, for all of reprap, and everyone who has contributed to it. But saying there is nothing wrong with it is straight up misguided.

That's the cfg from my photo https://github.com/Klipper3d/klipper/blob/master/config/generic-mks-sgenl.cfg Just confuses me more

If you have (like me) problems getting the auto reconnect solution mentioned on klipper https://github.com/Klipper3d/klipper/issues/835 running.

Did you check the printer cfg examples folder? Looks like there are a few BTT octopus cfg in there.

Compare your current printer.cfg with the master example here. https://github.com/Klipper3d/klipper/blob/master/config/printer-creality-ender3-2018.cfg

I found scripts to handle this problem, like this here: https://github.com/Klipper3d/klipper/issues/847

Guys, I hope someone who has it could send me the printer.cfg of the Ender 3 V2 Neo, I found it here on github, but it seems that some things are out and don't work the right way. Thanks!
