LinuxCNC (For lathe) install on Rapberry PI4 - Nov, 2024

I see there are previous threads about this, but things change with time and releases, so better to ask then chase my tail.

I previously setup LinuxCNC - Axis on a desktop PC for my mill, works great now I want to do the same for my lathe using a RaspberryPi4 Model B (4GB RAM, 32GB SD)

How do I go about this?  Some form of instructions would be very helpful.
Link to whatever version I should use?
Does the install prompt what type of machine this will be used (Mill, lathe etc)?
I ordered a A MESA 7i96S, not sure when it will get here.

Any helpful hints are welcome.

Thanks in advance.


 

Doesn't work as the RPi4 image was not created with SPI enable and no way to enable it
Menu-config does not have kernel option
Thus a 7c81 is still useless unless you do a debian install, compile the RT kernel, install LinuxCNC

SPI can be enabled by modifying the config.txt file and enabling the SPI option which is disabled by default.

sudo nano /boot/broadcom/config.txt

# uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
dtparam=spi=on
