Linuxcnc & the Raspberry Pi (4 & 5) Official Images Only!!!

As the image is a custom one, only the kernel is built from RPi Sources.
This pretty clear, I would have thought.
Where as you were attempting to install headers from the Debian repo

The kernel should load the drivers without any user intervention.

To one well versed in building distributions, yes, but not necessarily to one who has only used distributions! Not until now, anyway

I was but at that point, didn't realise the significance of the kernel being sourced from a different place to the base distribution.

It does now load on boot.

Thank you.

Just for completeness and to save anyone having to mess around with compiling kernel modules, here is what looks like a fairly comprehensive (at least until 6.13) list of in-kernel USB WiFi devices: github.com/morrownr/USB-WiFi/blob/main/h...in-kernel_drivers.md

Discovered it a little late but I think only one has an RP-SMA connection.

Dunn why RPi doesn't add a connector for an external antenna.

That would be lovely - the CM5 has one but then you need a carrier board and I don't know if the LinuxCNC image would run on the CM5/eMMC? With the right carrier board would be perfect though...
