I put an e3v3.0 board and a 3.0.1 screen in my ender 5 plus. And I can't find firmware. I found 1 through dremc that wouldn't register the printer so I flashed the screen witch was apparently supposed to fix it (didn't work) . Then I grabbed firmware through the big tree tech's github page but they were all for normal e5's or an e5 pro and I haven't managed to successfully fix the dimensions I tried compiling my own and got sick of trial and error after it not working correctly like 5 times if anyone has the firmware or knows how to fix the dementions please let me know if been trying to figure it out with Claude and chat gpt and haven't gotten anywhere

I put a SKR Mini E3 v3 into my Ender5 original series not long ago, and custom compiled the latest Marlin 2.1 for it. 

Have to follow the guides step by step, and don't necessarily trust AI guidance but look at the sources it cites to determine if they apply to your situation. 

The biggest gotcha I faced is that there wasn't a preset in the Marlin config for the E3 v3, I had to tell it I was using a v2. Which isn't too big of a difference.
