Configurations VS BIGTREETECH-SKR-mini-E3

Check Marlin‘s configuration repository at https://github.com/MarlinFirmware/Configurations for your specific board …

Go to the marlin github https://github.com/MarlinFirmware/Marlin and download the latest stable or bugfix release. Also, download the configurations that match the version of the firmware you downloaded https://github.com/MarlinFirmware/Configurations

Generally you would start with the Example config files from the Marlin Github https://github.com/MarlinFirmware/Configurations/tree/import-2.1.x/config/example

download Marlin configurations folder v2.0.9.6 from https://github.com/MarlinFirmware/Configurations

Current release, not bugfix branch? Started from the example config for your printer corresponding to the version of Marlin you downloaded?

Download the Marlin Example configs > https://github.com/MarlinFirmware/ConfigurationsThis contains the pre written configs for most popular printers so much of the config work is already done for you

I would add the Auto Build Marlin plugin (as well as PlatformIO) to your VS Code install, download the latest stable version of Marlin from the official source, along with the configuration examples. Copy the example Configuration.h and Configuration_adv.h for the Ender 3 Pro with Mini E3 V3, to your Marlin folder and compile that. The only important difference between an Ender 3 Pro and an Ender 3 V2, as far as firmware is concerned, is the V2 display, which you're not using, so don't use any of the config examples for a V2. The Pro version should have the correct serial port assignments:

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.

I went with this following the findings in this thread https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/issues/658

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

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?

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.

Pre-compiled firmware. (GH)
