Whilst I understand your draw to probe basic, I would recommend that you got linuxcnc up and working using one of the easier GUI's (easier = standard / default).....
When you started driving you probably didn't start with the newest and fastest car with the best performance available.... you figured out how it all worked first.. walk before you run.
I believe I have installed all the GUI's but getting to understand the process the frustration and nuances of what each requires and when an error is thrown up for a dependency as some of them are not very descriptive.
{I remember seeing something like .... bc not found .... what the "£$% is "bc"..... and how should I get it..... {sudo apt install bc} etc} point being "bc" (and other such short phrases mean nothing to a new user)}... hence the head banging.
Tommy has the link and Robert has good advice.
Python 2.7 is deprecated on Debian from Version 11 (bullseye) on. Its not possible to then install V 2.8 on Bullseye or Bookworm.
Linuxcnc adopted python 3 over 12 months ago. Its really up to the GUI developers to support Python 3. There has been plenty of time.
I have installed qtpyvcp and probe basic on Bullseye and Bookworm with Python 3 using the instructions on the QTPYVCP site several times..
I might add that I could not understand what all the fuss about Probe Basic was. It did not excite me,
For me, the whole attraction of using Bullseye or later versions of Debian is to eliminate Python 2.7, better hardware support and because the features I want to use are in master branch,
Hi Robert, I do actually have my machine up and running perfectly with a Raspberry Pi4, and I have tried all the default interfaces. I am putting a probe on the machine and Probe Basic seems to have that side of things covered! . It is probably hard to believe from my ignorant questions, but I am actually very experienced with linux, and write industrial Python code for a living!
my apologies, the posts seemed that you were struggling with the basics. I've not put linuxcnc on an rpi4 yet, have considered it for my lathe, but seemed too many issue posts on the forum.
with your experience you should not have an issue using the linuxcnc iso. I myself don't use the iso's any more when I have started from scratch and just get the Debian non free firmware iso (bullseye), use git for a local master build and build the debs and install. I have after dabbling with other guis gone to use axis as it just works and it's simple
