LinuxCNC-PC - Remora - OrangePi3 LTS - BTT SKR V1.4 Turbo

Ive started a new project.

I want to control a mini 3 axis cnc ive built, with LinuxCNC. The problem I hit, i have a BTT SKR v1.4 Turbo board, a PC and an OrangePi3 LTS SBC board.

The Plan:
Install LinuxCNC Debian on the PC. Install and configure Remora on the PC. Connect to the OrangePi3 LTS through ethernet connection. This in turn, will be connected to the BTT SKR v1.4 Turbo board via SPI. The SKR board has the latest LPC1769 supported Remora firmware installed on it.

Follow this repo for my progress. Feel free to collaborate!

Nonsense.
This will be not cheaper and not better than chinese 7i92 + cncshield (~60 US dollars on Aliexpress).
I have small table milling machine controlled by ESP32 + W5500 + cncshield (hal2udp project) - it is cheapest solution and work well.

Actually this is cheaper. I already have it running on GRBLHal, and I fancied a challenge.
I have all the hardware, so buying supported/prebuilt hardware, is more expensive…
Plus, this could open up a lot of extra windows and doors!

Am I understanding correctly, the Pi in this project exists purely for bridging ethernet udp <-> spi?
I am always interested in new ideas. Sometimes new ideas hatch breakthroughs.

Yes I believe you are.
PC → Ethernet → Orange Pi → SPI → SKR

Again, read. Through my repo. It explains everything! In depth!

You're wrong.
You will waste a lot of time (that's also money) and you will reach a wall that you can neither get around nor jump over.
Short time ago I have removed four Remora EC500 from working machines, because this project has no future.
I spent many hours with this hardware and not solving some troubles (stupid 3,3V differential outputs not fitting motor drivers and not working spindle encoder).
I bought four Chinese 7i92, because it was cheaper and better, and now I have many time for other projects...
