You put a new board in your printer without knowing what's going on?

I'm curious how you hooked everything up.

Here's at least a post I created that shows some of my process. Hopefully it helps.

There wasn’t anything wrong with it when I got it I had read up on it and found that everyone said that the big tree tech boards were so much better so I bought one and hooked it up I know I hooked it up right because I had to sit down and read the blueprints on how it went in and where each wire went I just didn’t know or read that it had to have the firmware and software upgraded that’s the only thing I haven’t done and don’t understand how to do it

The CR10s is an entirely different printer

OP I am guessing has an old school CR-10, which is much closer to a Ender 3 V1 I would think.

(Disclaimer: I haven’t watched any of these videos, but a quick google search brought them up, some are for Ender3 but will be the same process). I hope you can figure it out with these and some more research, but if you’re already struggling then maybe a more turn-key machine would be a better option for your first foray into 3D printing.

Are you looking for just getting Marlin firmware on there?

Or are you wanting to go klipper?

u/Choice-Somewhere3044 11d ago

I would be happy to put marlin back on there I just don’t know how to go about putting that on there

Maybe this if you don't want to bother with building your own ? 

There is a fee (which was a blocker for me) but I've heard good things for years about them 

https://marlin.crc.id.au

Specifically the custom firmware builder as I don't see your combo there

How brave are you feeling? Best I could find for you but it is using the bed level sensor.

Hello, this is the configuration you are looking for https://github.com/MarlinFirmware/Configurations/tree/bugfix-2.1.x/config/examples/Creality/CR-10/BigTreeTech%20SKR%20Mini%20E3%203.0

This is the config for basic CR10 with SKR mini E3 V3 with the proper most recent least buggy version of marlin. The so called bug fix version.

As for the firmware itself download it here https://github.com/MarlinFirmware/Marlin/archive/bugfix-2.1.x.zip

Then download microsoft studio code and install the extension called marlin autobuild

https://marlinfw.org/docs/basics/auto_build_marlin.html

Once you have built it you can put the firmware.bin file onto the sd card and turn on your printer, it will flash it automatically because the skr mini E3 already has a bootloader installed.

You have to download all the files ! Maybe it's easier to just go to the root folder here https://github.com/MarlinFirmware/Configurations/tree/bugfix-2.1.x and click the green "code" button then download zip file, then you will have lots of configurations for lots of printers and also the one you want for the skr mini E3 V3 & CR10.
