RPI4 Raspbian 64 bit & LinuxCNC

I downloaded and installed the microSD image you provided a link for above. M RPi 4 booted up and asked for a password. I've tried "raspberry", "password", "linuxcnc" and several other guesses but nothing works so far. And I don't know how to change it since it boots right into the gui.

But what is the link from which you took it?

Some of the images out there are a single user called "root" with no password.
Which isn't ideal, but I think is a reaction to the existence of several million RPis on the net with a user of Pi and password "Raspberry". I am not clear on how passwordless root is better, though.

Here is the link you posted on March 22, 2022

linucnc-2.9.0pre-bullseye_arm64rt.zip

For the record, today I have started to build a Bookworm based linuxcnc installer in a chroot/cross compiler environment using this repository.
github.com/pyavitz/rpi-img-builder
I hit some unexpected errors and have got some amazing support after I logged an issue there.
Building the preempt_RT kernel seems to work. Once I get that done and tested, I'll be building Linuxcnc from the latest source in the chroot environment..

I might add that my choice of a user name of cnc and a password of cnc is not  much better than a blank root password!
I hope it will be together in a week or so.

Maybe the new linuxcnc Buildbot can be taught how to run this as some RpI Debs are sorely needed.

I Think the password is = cnc
