Controller recommendations (other than mesa)

ESP32 is 3.3V and it is too low for some drivers, but some will works.
Wires are wires, the problem may be with poor quality connectors. Some are good, some can be repaired, some are useless, it depends on which ones you get.
I agree, the wires to W5500 must be as short as possible.

Sorry i forgot about this, mainly because i tested several drives and all worked fine.

This is a LinuxCNC forum, not a general CNC forum. we should not be discussing alternative CNC environments. Personally, I chose LinuxCNC because it can handle whatever I throw at it, accepting the learning curve because as I built different machines, I could keep using it.
With LinuxCNC, building with a parallel port gets you going with an old PC and a $10 BOB  is far superior and probably far cheaper to something like a grbl board and leaves you with an infinite upgrade path.

I have several machines controlled by LinuxCNC and I think this is the optimal choice. I also have a CO2 laser controlled by Makerbase MKS32 with FluidNC installed, which I operate via WiFi from my laptop used for design. I can't imagine it, and no one will convince me to install an old PC with LPT and a monitor there. There are also people on the forum who ask how to use LinuxCNC where a PLC or even the cheapest microcontroller is enough. Yes, LinuxCNC is great and can do almost everything, but that's no reason to force it on everyone and everything.

Do "old PCs" still have Parallel ports? .

Some modern ones do.
There are PCI or PCIe to LPT cards too.
But this does not mean that a given computer is suitable for LinuxCNC because it has LPT port or LPT card.
There are other factors that determine this.
