Thanks so much for this. I am still in the research phase before setting out to build my first router but having this will such a help once I get there.
A delight to watch. Helping progress the cheap lathe and fadal 15 one upload at a time.
That boo in the background was great. 🤣🤣🤣
Nicely done, thank you.

Just trying to contribute in my own way 😊
As I'm following along I don't have the Grub file that you edit @13.31 have I missed a step?
Synaptic package manager -downloaded Mousepad, "sudo mousepad" -open filemanager -open etc -open "grub.d"
and I got this... (In the README file)
All executable files in this directory are processed in shell expansion order.
00_*: Reserved for 00_header.
10_*: Native boot entries.
20_*: Third party apps (e.g. memtest86+).
The number namespace in-between is configurable by system installer and/or
administrator. For example, you can add an entry to boot another OS as
01_otheros, 11_otheros, etc, depending on the position you want it to occupy in
the menu; and then adjust the default setting via /etc/default/grub.
I don't see a "grub" file. But I see you have a "grub.d file"
I think i'm missing something!
Thank you for the helpful videos. When I tried to the install it failed on the installing the grub bootloader. So once it was finished I couldn’t boot to it. I was putting it on its own seperate SSD. Any idea how to trouble shoot?
If it's a newer computer, make sure your bios is not set to UEFI. You need to run legacy mode or that will happen.
@@TheFeralEngineer thank you I will look into that.
I had good luck reducing my latency by installing an extremely cheap graphics card. Running with the onboard graphics gave me terrible latency but buying the cheapest graphics card I could find cleared it all up.
I've done the same. Mine was more to get the computer I was using to run probe basic, though. Latency was fine. Card only cost 50 bucks and the computer was free besides needing a power supply.
@@TheFeralEngineer I do appreciate this. I am going to try turning off cores in my processor. Even with the graphics card my latency is still around 33,000 but without the graphics card my free computer was around 200,000 when pushed hard. Wouldn't mind getting it down in the 15,000
Great job!
When I will understand more detail I will make tutorial on my first language too. (I'm use MESA cards too)
Did you show the difference before and after "isolcpus"?
I did, but the audio got garbled, so I had to cut it
@@TheFeralEngineer I never did the "isolcpus" so i don't know the difference. (the PC with LPT has an AMD CPU with one core)
@@DPTech_workroom if it's only one core, isolcpus will not work. It's only for multicore possessors. You can verify the number of cores and any isolcpus that may be running with latency-histogram
@@TheFeralEngineer My notebook has 2 cores for Mesa cards. (Core 2 Duo T7400)
@@DPTech_workroom you can try isolcpus on that and compare the difference pretty easily 👌
Time stamps please to get past the usb liveboot install as you already did that in the first tutorial.
Yeah, that's why the title said 1.5. it was a little redundant but more detailed. I have to get around to time-stamping my videos.
we have just started to use Linuxcnc and in the process of watching a few of your videos, in this video we are told we have to access the GRUB by going into the terminal emulator and typing in Sudo Mousepad we then get a pop up box with untitled 1 - mousepad from here we are told to go to File - Open - file system - etc- Grub, our problem is that there is no GRUB just GRUB D, we are using Debian 10 with linuxcnc has anyone got any idea we’re the GRUB file is located
Thanks in advance and great videos
Please timestamp it in the video so I know where to look without having to watch the entire thing over. I don't think this is the video where I mention modifying grub, that's in my debian 11 video. You shouldn't have to access grub with the prepackaged ISO
@@TheFeralEngineer it’s definitely in bare bones tutorial part 2, you had been talking about the latency test at 8.11, our test is high so we continued to watch and you did something with grub at 13.00 to 13.30 this was to change a line of code “quiet, isolcpus=1”
We assumed that since we have high latency on the test that we had to isolate core as we had seen yours come down after doing this change in the Grub, but we are only running linuxcnc through this pc it’s not a dual boot so do we even need to do this stage, we have had problems with Mach 3 so wanted to do this correctly and didn’t want the steps affected in any way if you could advise us on this, many thanks
Hello there, How you install WIFI.
Why didn't you call thus one Part 1 again?
It wasn't quite part 1, it wasn't quite part 2... It augmented part 1.
