Linuxcnc Image for Raspberry Pi 3

i just order some shift level converter can use whit rpi gpio can make out 3,3V to 5V all gpio pin, and then one optocoupler board can add rpi inputs safe, 5V in to 3,3V to rpi,
then can add all STEP,DIR,Enable pins traight to drivers DM556 i used normal,
but problem is were have image can use rpi3, not need be fast, this come only dovetail jig tool make long plank top dovetails not more, no need be full cnc, working area has need only XY axis, what has moved Z axis to 90 degree and spindle have horicontal not normal vertical system. simple hardware but image need old rpi3 board first.

what is kernel and what is compiler, how use or how install and use. what is repos and scratch. not understand code nerd super engineer language. (translator not help this)

There are no premade RPi3 images available for download.

You have a couple of options.
1: Someone maybe able to make one, but it would require that person having access to a Rpi3.
2: Find someone with Linux knowledge who can also speak english and is willing to help.
3: Have a go following someone's instructions, all is not lost if you make a mistake.
4: Look into using grbl.

A bit of a warning regarding the RPi3, you may have latency issues, which there may not be a solution for fixing it. Increasing thread period may not give smooth operation.

Saying that you don't understand all the time wont help. I'm sorry I really wish it was different.

This is catching my interest. I think I will try it. I have at my fingertips a Pi 3 Model B+ but it is not working, not sure why. Maybe I dropped it a while back. I also have a Pi 3 Model B V1.2, I have it running a fresh install of Debian 12 Bookworm.

Now it is installing LXDE.
Next up is realtime kernel, I'm looking at linux-image-6.1.0-41-rt-arm64
And then LinuxCNC....
Fingers crossed...

Got LinuxCNC built. Running latency test. Tried running Axis and QtDragon, gui just crashes, need to spend a little more time on it, maybe tomorrow. I think I got some missing dependencies going on.

Wow, I can hardly believe I did this to a pi 3. The simulation is running. Next I want to check if gpio and a couple other basics work. The latency numbers look a bit sad.
Still no luck starting QtDragon.
