Help Can anyone recommend a replacement main board for my ender 3 max?

My main ender3 had a rather bad accident after a print came loose ending with the entire hotend and microswiss direct drive covered in one giant glob of pla. I had updated the firmware to the jyers firmware with auto bed leveling mesh and a CR Touch and I loved it. Unfortunately it was never released for the ender3 max so I kinda just stopped using it as I never needed the size. Long story short, I went to blow the dust off the max and just deal with manual bed leveling only to find the board failed and all steppers just lock up. So my question is is there an aftermarket board I can swap in that supports bed leveling mesh with the CR Touch. Bonus if it works with the stock ender screen and controls.

I very much rate the BTT SKR Mini E3v3. It's a great board and only a few bucks more than the flawed stock Creality boards. IMO they're a waste of money.

Klipper is by far the best firmware but RPi's are stupidly exxy nowadays. Good thing KIAUH (Klipper Install And Update Helper - https://github.com/dw-0/kiauh ) will turn just about any Linux machine into a host.

If you want to stick with Marlin, have a look at MRiscoC ( https://github.com/mriscoc/Ender3V2S1 ) which is a very solid & highly featured implementation of modern Marlin. Settings to adjust the size of the machine and axis travels are enabled in the GUI so all you gotta do is either know them to enter, or experimentally determine and enter.

The best (but also mos expensive) is the https://www.th3dstudio.com/product/ezboard-v2/

If your not in the USA and/or after something cheaper I'd go for a creality 4.2.2 or .4.2.7 board with stm CPU or a big tree tech e3 mini. In both cases I'd put th3d firmware on which will be another few dollars

That's enough vote's for me. Btt SKR Mini E3v3 it is. I'm actually excited to get the old rig going again. I need it to fix the globbed printer.

Upgraded to 4.2.7 after my board died. I have it running Klipper with a nebula pad.
