E3Pro auto home malfunctioning

Euuugh. That's a tangled web. Technically, the 4.2.7 board is supposed to be a simple swap in, but I'm seeing an awful lot of posts where that hasn't worked, and firmware twiddling was required. This feels like a firmware issue, but it's going to be difficult to diagnose as there are so many potential Ender 3Pro variants out there.

What happens if you chuck the original board back in. Does it still do the raise, stop, raise, behaviour? That might at least get you printing again.

I assume that your E3D pro doesn't have a touch screen?Do you know if it has a transfer board installed or not? (see point 8, here - https://howchoo.com/ender3/install-b...ender-3-v2-pro). It shouldn't affect anything if there's no BL Touch, but any information is good.

And yes, this forum software is bad.

Man, you sure do exhibit tenacity and perseverance! OK, I will put the V1.1.4 board board back in. Neither it nor my 4.2.7 board have touch screen, BL, filament or transfer capability built in. It seems that the V1.1.4 doesn't have a bootloader installed so firmware flashing must be done with Marlin, Octopi and a Raspberry Pi--right? I actually do have a Raspberry which was used when I had a computer tech come out back when to flash the V1.1.4--all that is beyond me!! (That was an interesting session because he knows NOTHING about 3D printing and I had to preassemble all the download sites, YouTube how-to vids and programs like Pronterface, Visual Studio, Octopi. Can you imagine ME trying to help him through all that???? He is a dear friend who indulges me greatly! I sense we'll have to do something similar again.) But I will put it back in and use the original SD card content that came with the board if necessary. More to follow later....and another big thank you for now.
