Sorry, why not ? i like the RPI's, especially via SPI

It is 150 Euro here, be it 4 or 5, i can get a full used PC for that money.

wow, ok, in germany/amazon (not the cheapest):

Pi5/4GB = 67,84€
PI4/2GB = 47,80€

They'll never be under $50 again. The world has changed, $50 is no longer $50.

That is very true.

Hi Linuxcnc community, 
I have installed OS in raspberry 5 and Instead of using IO expander I want to use individual ESP32+W5500 for every motor and generate step pulses. If this is possible please help me with the steps in achiving it.
Refer the image below and get what I want to achieve

Rather than using many ESP32s, I would try a W5500-EVB-Pico
shop.wiznet.eu/en/w5500-evb-pico.html
and Remora software for RP2040
