Marlin 2.1 setup for Ender 3 V2 and SKR Mini E3 V2.0 (by NathanBerglas)

BIGTREETECH SKR-mini-E3 motherboard is a ultra-quiet, low-power, high-quality 3D printing machine control board. It is launched by the 3D printing team of Shenzhen BIGTREE technology co., LTD. This board is specially tailored for Ender 3 printer, perfectly replacing the original Ender3 printer motherboard. (by bigtreetech)

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?
1 project | /r/klippers | 28 Nov 2023

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"
1 project | /r/BIGTREETECH | 12 Sep 2023

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.
