- How to install network manager if you don't have it on your official install distro and how to try lowering latency with isolcpus

Love your work Phil. I spent half the day today looking through Google on how to replace wicd with the network manager. You helped me out in less than 10 minutes. I love the fact that you do it at a slow pace so it really helps out noobs like me. Keep up the good work mate.
Happy to oblige, sir 👌👌
Thanks again Phil , I like the slow pace.
Slow and steady 👌👌👌👌
Great video….I’m getting closer to setting up my Mesa.
Hello,
I’m a subscriber of your channel and thanks for all LinuxCNC videos.
Could you please make a video about how we can install Probe_Basic GUI in LinuxCNC environment.
Since Probe_Basic installation instructions is changed, it’s now very complicated to install.
I appreciated for your time.
Have you tried the Dragon interface? It's built into LinuxCNC and is a direct competitor of probe basic
Hello there, make command doesn't work in LinuxCNC v 2.8.2, I'm trying to install Realtek wifi driver but can't use make.....
hello Phil for some reason the option for subtitles is not available... i can only follow the tutorials reading in english but it is still hard for me to liste and understand it ..i congratulate you for the tutorial..
You are right, wicd is hopeless. Rebuilding the debs without it is on my list.
However, I am not convinced that installing anything gnome is worth the overhead.
The updated ISO will probably install nm-tray which seems to do the trick.
Thanks for the heads up, Andy 😊. There are so many options for things to install that it's almost impossible to keep up with what's available. Network manager gnome was the one I was using originally (when I installed stretch from the testing folder), so it was the one I was most familiar with. Figured I'd go path of least resistance for the masses. I'll install nm-tray on my laptop and poke away at it.
@@TheFeralEngineer Well, I was having problems on my little test machine (It's a Beelink SFF system that I bought purely as it was the cheapest UEFI machine on Amazon that day and I needed to test the ISO and wanted to spend as little as possible.) I installed nm-tray and that auto-installed network-manager and as if by magic I had the 7i80 on ethernet and my wifi network in the wifi with no further intervention. (I had connected to the Wifi during the ISO install, so it had the credentials available. The pint is, it found them)
@@andypughtube I'm gonna give that a go tonight for sure. Anything that makes LinuxCNC a little more friendly for the masses is a-okay with me 👌👌
this is really helpful! Do you have suggestions to get ping latency down?
I do not, sorry. Have you tried the forum?
I'm picking up some good tips. Can you show how to use Linux to access a network drive. I've setup a flashdrive as a network drive on my router. My windows computer in the house can see it. But my Linux machine in the garage cannot. Would be nice not to carry a flashdrive back and forth with gcode files on it. Cheers
If you follow this procedure, it may help you out. I just tested it on my laptop and one of my dual boot computers (all of my CNC machines run dual boot) and this worked. You just have to make sure you pin a shortcut to /mnt/share so you can access it easily

👍💪
Hey thank you for the videos. I'm trying to get the network.manager for my system but keeps getting connection fail(my crappy internet doesnt help). I'm using a 4 GB raspberrypi 4 as my system shouldn't be using this manager or a different?
There's a different one. You have to configure it inside of a text file. I'm not home until the end of the week, to pull up the info, but I'll try to get you what you need
@@TheFeralEngineer thank you. After several attempts it did install the network manager gnome. But the old network manager isnt called wicd. Just says network manager.
What does the ifupdown do?
@@mastermoarman yeah like i said, this procedure won't work for raspbian, it uses a different setup.
Ifupdown let's you use wired and wireless connections simultaneously.
@@TheFeralEngineer thank you
If I'm on a single core (Celeron 450) how would I go about lowering latency?
I've tried xanmod kernel and a few others but it doesn't seem to help.
What's your current latency? You running Mesa hardware or parallel port?
@@TheFeralEngineer parallel port for now. Max jitter on Servo thread: 50120
Max jitter on Base: 27198
That's with 5 instances of glxgears open.
As soon as I resize one of the glxgears windows quickly it jumps.
Max jitter Servo Base: 154537
Max Jitter Base: 120734
Edit: Those figures are with the RTAI kernel on 2.8.2 Wheezy setup.
Surprised rtai is giving you that much jitter. Onboard gpu or pci/pcie?
@@TheFeralEngineer on board GPU. I don't have a low profile GPU to try out at the moment unfortunately.
Was considering grabbing a core 2 duo with higher clock rate and a cheap ATI GPU.
@@chrstofuchaos i bought a gpu and a conversation plate for low profile, but something a little more modern might be good. Just make sure it's not too new with windows 10. Uefi is a pain in the ass to work around.
Here's the gpu i used. Price went up, probably from chip shortage and everyone trying to make a fortune in Bitcoin 🙄. I can send a link to the plate, also.

Very nice, indeed ! :)
Do something about accepting crypto (and the subsequent change to "real" money), i will gladly buy you a beer or two...
I'll work on it 😊😆
