It is Buster then but only 32 bit. Is your machine capable of 64 bit? lscpu in a terminal should tell you.

I think your choices are:

Blow it away and install Buster from this ISO:
www.linuxcnc.org/iso/linuxcnc-2.8.2-buster.iso

Try this solution to move to 64 bit. You would additionly need to install a preempt_rt kernel.

The computer is capable of 64 bit, see output of lscpu :
Architecture: i686
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
Address sizes: 39 bits physical, 48 bits virtual

But I have used that ISO you point to to setup this machine, I thought that was a 64-bit installation ? I am a bit hesitant to start from scratch, we have had enough headaches to get the thing to work Not sure what to do.

You need an x86_64 or amd64 processor for the 64bit linux distros and also the Buildbot package that includes QtPlasmaC.

With the processor that you have you are stuck with the package version you have. You could try building linuxcnc yourself. That has no effect on a package install and they can run side by side. It is not too difficult and once done then you can also update quite easily at any time. You can get it up and running a sim config to make sure it works without conflicting with the existing install then I can help you make a QtPlasmaC config to suit which is also not too difficult.

Hi Phil,

Thanks a lot for your clarification. We were in the process of setting up a new computer combined with a MESA card to replace the current setup with an old computer and parallel ports, but work is catching up with us and we didn't get around to finish that setup yet.  We will nurse the current setup through harvest season and then we will pick up where we left with the new computer.

Thanks again for all your help, I understand it is time consuming and all done for free, which makes it all the more miraculous that QtPlasmaC is such a refined bit of gear. Kudos to all who make that happen !

Cheers, Peter
