help newbe!

Hi

Putting together a cnc machine for my milling machine. I have no experience in Linux.
This is the computer I have.

Mother board-Asus P5E deluxe
CPU-Pentuim Dual core E5200@2.50Ghz
Memory-8 gigs of ram
Video-Nvidia GeForce GTS 450
Hard drive-40 gigs

Software-Linuxcnc 2.9.1 -amd64.hybrid.iso, software is installed and working on the hard drive
From the terminal-sudo apt update and sudo apt upgrade were downloaded (how do I install these packages?)
Legancy test- 25887(1ms), 29946(25us) are good values or should reduce them lower?
Please help me with direction as I find I'm having problems understanding the documation(I'm just getting to old to figure things out  Lol!)

Thanks
Fred


 

sudo apt upgrade installs any updated packages so there is nothing to do!

I checked the realtime kernal
typing in >uname -r
and it came back with>6.1.0-13-rt-amd64
is this correct?
what else do I need to download/install ?

also 3 programs were running(utube,glxgears,just using the computer)
and the latency test results were
25478(1ms) 34675(25ms)
these numbers tell me both values have to be lower
what direction would improve latency, software or hardware?

Hardware is best bang for buck, or grab a Mesa card and don't worry about a base thread.

Personally I'd go the Mesa route (ethernet), and in the future an upgrade (computer) is really simple.

Yeah almost everyone will recommend Mesa hardware, but it's reliable, plenty of IO options, great support and Pete from Mesa is a top bloke.

I was going to start with the parallel port, get everything working plus learning the software. Going to the Mesa (ethernet) was going to be my second upgrade.
Currently the jitter 18207(1ms) , 26343(25us) are these number okay to get going?

I ran Latency-histogram, in the top header couple of lines down. it said-
2 cores no_isolpus Genuine Pentium dual core cpu e5200@2,50ghz
looked it up in mousepad file, open,filesystem-etc-grub could'nt find grub but found grub.d. Could'nt locate the correct grub file to install isolpus=1
where does the isolpus=1 go?

pretty sure I added grub-customizer to the 2.91  ISO so
type 
sudo grub-customizer,
Select the second tab.
In the field that says quiet make it: quiet isolcpus=1
Save and reboot, latency-histogram reports the isolcpus setting.

thank you
it worked!
