Its a shame, and I'd like to use the board on my CNC router.
I understood some of the reasons for the MachineKit fork, but always
thought it was unfortunate that there had been a fork in the first
place.
I really would prefer to use LinuxCNC on the BBB, but would need an
idiot's guide to installation.
I have just managed to buy an 8Gb Pi 4 and had hoped to run LinuxCNC
into my 7i96S for my small CNC lathe.
I would be disappointed if LinuxCNC on the Pi is not currently being
supported.

I'm curious. I have one of the original Xylotex boards. The link to
this web site implies there's a newer version along with a link to 4GB
BeagleBone Image for MachineKit which I have read hasn't been
supported for years.

My BBBs (3 of them) are all sitting in a box unused. This includes
things like LCD displays, CAN bus capes etc. I had thought about
adding the BBB with CNC to my Gingery Lathe which currently is
controlled by my Electronic Lead Screw product.
What is the status in general with the BBB and MachineKit or LinuxCNC.
Should I just put my stuff on EBAY?
I ask because I also have a 1GB Pi4 with a MESA 7i92H as a desktop
play toy. I think the 1GB is a bit small for LinuxCNC but so far it
has worked. I'm not sure whether support for LinuxCNC on the PI4 has
also gone by the wayside?
So if someone had a BBB and a cape, installs a version of LinuxCNC
(MachineKit) do they run into what appears to happen often now with
trying to upgrade and unknown web links?

It's a replacement for the sysfs interface for gpio (which hal_pi_gpio
uses, for example).
There is an article about it here:
https://lloydrochester.com/post/hardware/libgpiod-intro-rpi/
I have a working-but-slow demo here:
https://github.com/LinuxCNC/linuxcnc/commit/15138feb4a1a811a7b61a6605
55d78b85bdcf86c
(later commits in that branch are not working at all at the moment)
to use the BBB output from gpioinfo above:
loadrr hal_gpio inputs=P8_25,P8_24 outputs=P8_10,P811
