SKR 2 Laser Engraver
If you look at the pin diagram on BigtreeTech's github pages, it will tell you what and where all the pin names and numbers are.

SKR 2 not turning on when connected the 24v power supply
I connected just the power supply and not turning on anyway. I find this https://github.com/bigtreetech/SKR-2/issues/144 It seems like it's a known issue lol. I'm turning this crap back to them. I have really bad luck for electronics 🤣

Help with skr 2 board, it caught on fire today!
Yes. It replaces the z endstop on the 5+. There is a section on how it should be connected in the user manual. https://github.com/bigtreetech/SKR-2/tree/master/Hardware

Any idea why this near fan 1 would burn out like this. also is this still usable?
Have a look at the github for the SKR 2 here. In the hardware folder, they've included pinouts and schematics.

No printer attached. Marlin not working. No idea how this started. I’ve read around a lot and tried multiple firmware updates; I even took the bottom panel off to see if anything internally was loose. Any idea what to do?
For skr 2 you need to look at the numbers on the chip. There is a STM32f407 and STM32F429. These are the current official BIQU B1 firmware. https://github.com/bigtreetech/BIQU-B1/tree/master/Firmware/2022-03-27 select the one that matches the chip number. I recommend doing the screen too. Look at the screen chip too since there is a chance of it being a GD version instead of the STM. The chip shortage problem has made it so they need to use equivalent alternatives so it's important to choose the correct firmware.

my printer never was this noisy before.
I've updated my biqu b1 to the latest version on githup: https://github.com/bigtreetech/BIQU-B1/tree/master/Firmware

BIQU b1 se plus display not working
Looks like you will have to reflash the firmware on the screen. This link Here should provide you with the correct firmware (pending its the newest) then put it on an SD card and throw that into the SD slot on the front of the machine.... DO NOT PUT THE SD CARD INTO THE REAR SD CARD READER!!!!!!!

Hey Big tree tech! Thanks for caring about your customers safety. Swapping in a h2 direct drive hot end and this is the first heater cartridge no only accessory I’ve seen with proper connectors. You better bet my shopping will be only with you now!
Hmm, not the experience I had but I can see how that's not too helpful. Did you ever get it sorted out? It's pretty straight forward if you still need help. It's just download the newest one for your motherboard from their GitHub repositorie put it on an SD, insert the SD into the motherboard sd slot. Turn on the printer. It updates in couple seconds without a visual confirmation. You can confirm the update by looking at the SD on a PC and see the firmware.bin changed to firmware.cur.

Biqu B1 SE plus Auto Bed Leveling not finishing the process
for the probe not finishing it sounds like a firmware issue and you will need to update and fix that before you get full functionality out of that you can find the firmware on https://github.com/bigtreetech/BIQU-B1
