Which version for just running simulation on desktop or laptop

I would like to install LinuxCNC on my desktop (Mint 20.3) or Laptop (Mint 21), only to test some HAL modules I'd like to write. Do not want to change to an RT kernel. Will the base and servo thread still run at roughly the same speed as with an RT kernel?

The newer versions (LCNC 2.9, 2.10) require Python 3.11, which is not yet available on my Desk/Laptop, and I do not want to override the system Python default.  Does that mean that the latest version I can use is  LCNC 2.8?

(I use LCNC 2.8 on 2 CNC systems, but I do not want to run my HAL module tests there).

Thanks,
Rob

You don't need rt for what you are doing.
Why don't you run a VM with debian Bookwom installed on your computer? 
 I do that using Virtual Box or VMWare Player on Windows but you should be able to install them or something similar on Mint

Thanks, I might do that.
Of course, installing LCNC 2.8.4 does not work out f the box either; it complains about python2.7-glade2.

I find it strange that LinuxCNC - a a true Linux application - does not install out of the box on many of the current mainline Linux OS'es. It is a very versatile product, but this does not help promoting it.

Ubuntu 23.04 works out of the box, install, update, upgrade, then
sudo apt install linuxcnc-uspace

That is good to hear, thanks.
You mention in another thread that

'I do have it installed on another PC with Mint 21.1, works perfectly.'

As I run Mint on my desk & Laptop, which version is that?

On Mint 21.n i use an older build of 2.9PRE from the Debian repositories that is not awailable anymore.
For 19.3 there is a how to here in the "installing LinuxCNC" section that still works for 2.8.4.
Having said that, compiling works always on any Debian based distro, i did build 2.10 two days ago and after satysfing dependencies it builds without issues for SIM and RT.
See the docs on building from sources, use only the part for building packages, not the top/run in place part.
That gets you SIM for 2.10 or Master that is still in development and is the latest, coupled with the bugs you might encounter.
At any time, if you want to run a machine, just install the RT kernel and boot said kernel. No need to recompile.

The real problem with Linux mint is they are several versions behind Debian despite being Debian/Ubuntu based
This means they are missing the dependencies in their repo that Linuxcnc now requires. Unfortunately, I have totally given up on it a long time ago.

OK, Thanks. I have a second laptop; I'll put Ubuntu 23.04 on it.
