How do I fix this? I’ve tried everything. I installed an skr mini v3.0 and reflashed using their own bltouch precompiled firmware and nothing seems to work.

Build his own firmware?

Last week I ugraded the mainboard to a BTT SKR mini E3 v3.0, and I just used the "firmware-USB.bin" from the GitHub page to flash that board, and I updated the pin names on the printer.cfg for my printer using the example on that same GitHub page. Everything is working well, the printer in producing good parts like it did before.

Disconnect 2 wires and hook it up to the Z-stop. Will probe, but it hovers about 25mm off the bed even when the z axis is brought all the way to 0. It will not go to negative values. Tried both the BLtouch and BLtouch-for-z-homing firmwares from here(https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/tree/master/firmware/V3.0/Marlin) but no luck

At this point I've narrowed it down to the Klipper firmware being sent over to the Mini and after it boots. Looking at BTT's github, it is included in Klipper now. So I used the build scripts there through KIAUH. Set up the information to send it over USB and it flashes without error. I tried with Serial USART1 PA10/PA9. From the printer.cfg
SKR Mini E3 V3 Ender 3 issues "no printer attached" and "system: no system"

at some point, I was also trying to update the firmware. I have a BL touch installed at the same time so I tried to use the V3.0 Marlin firmware (https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/blob/master/firmware/V3.0/Marlin/firmware-ender3-bltouch.bin). I have no idea if it ever updated the firmware as there was never anything indicating it was installing. I assume I put it on a microSD, and plug it into the motherboard right?
Help - Cr touch / SKR mini e3
1 project | /r/ender3 | 24 Aug 2023

I recently made my first upgrade on my ender-3, a Bigtreetech SKR mini e3 v3. I also bought the official Creality CR touch and installed it onto my printer. I plugged the cable into the adequate spot on the board and unplugged the cable from the Z endstop switch. I then downloaded the firmware (firmware-ender3-bltouch-for-z-homing.bin) from this page: "https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/tree/master/firmware/V3.0/Marlin" and uploaded it to my printer.

Firmware update.

I would strongly recommend against creality firmware and instead get this https://github.com/mriscoc/Ender3V2S1/releases
Help!

Try to search on YouTube. If you have problem with 3d printer not detecting se card, try to use some other sd card that didnt came with 3d printer and change the name of firmware files (3d printer won’t install files if you don’t change name). Follow tutorial for formatting sd card and what firmware you would need. And I would install this firmware, it is better than stock one.
What does this mean, is it fine?

Some of the s1 have a warped bed I had one like that. Swapping to professional firmware with UBL helped. I don't recommend any of the ender machines except the ones from this year anymore https://github.com/mriscoc/Ender3V2S1/releases/tag/20231202
