Asrock Q1900M: Unexpected Realtime Delay, but Good Latency Values

Category: General LinuxCNC Questions

the J1900 dosent have hyperthreading, nor dose the board have tpm, i disabled all the low power c states, onboard audio, the igpu (machine is headless).

If i could somehow repoduce the latency excursion in latency-test/ or the histogram that would be great, but i cant get it to happen.

Try:
OA+ A+
OA- A-
OB+ B+
OB- B-
Then open "show hal configuration" from "machine" menu, there on the right side choose "watch" and on the left side choose 7i92>encoder.0>encoder.0.velocity or encoder.0.raw-counts
Do this for all 6 encoders so you can see all at once and turn the spindle by hand.
Does any encoder count?

Did you disable hyperthreading, TPM, power saving, pci-e power management, turbo, etc in BIOS?

Thanks for your thorough explanation. Much appreciated! I will certainly give your build a try and I may decide to use it for the new machine that I am working on. I always love to try new things, pushing the boundaries of my comfort zone :)
As for Clear Linux, I have not seen any recent progress on their end to build a bundle for LinuxCNC. They got beyond the point where I got stuck, but it is still a work in progress. I reached out to them two weeks ago, but have not received a reply yet. I know they have a lot on their plate, so it may just be a resource and priority issue. Time will tell.....

Category: HAL

Yeah got it.
I git cloned the source and as it's C and I've been reading C see since K&R was the hot book to have (like 50 years) it didn't take long.
Track back and discover it's in the NigMill.ini file
but   but  didn't I try that already?
Recheck. There was a section
# [SPINDLE0]
# MAX_FORWARD_VELOCITY = 1500
# INCREMENT = 100
So I just whipped off the # on the first and last line and retried it, got nothing.
Sad. Miserable.
However the dyslexic old coot that I am missed the real section name was SPINDLE_0
[SPINDLE_0]
# MAX_FORWARD_VELOCITY = 1500
INCREMENT = 1
and it works. I can increment and decrement in 1rpm steps.

Danke für deine Antwort Timo 
File Attachment:

Der GND und +5VP sind allerdings Ausgänge für Encoder, zB Glasmaßstäbe die selber keine Stromquelle haben.
Der Encoder vom Servo bekommt aber Strom von der Endstufe und benötigt GND und 5VP nicht, allerdings sollte man darauf achten das die angeschlossenen Komponenten das gleiche Potential haben, deswegen habe ich gestern auf Rat eines Elektronikers GND vom 24V und 5V Netzteil zusammengelegt. Gebracht hat es aber auch nichts.

Ich bekomme diesen Encoder nicht ans laufen und habe absolut keinen Dunst, warum nicht.
Der Servoencoder selbst sollte funktionieren weil in der Endstufe die aktuelle Drehzahl angezeigt wird, reagiert auch sofort auf Drehen von Hand.
Seit ihr bitte so freundlich und schaut euch meine Hal und Ini Einträge dafür mal an ob da ein Fehler drin ist?

Ich habe ein paar Ausgaben von Mesaflash angehängt, womit ich ehrlich gesagt, nicht wirklich schlauer wurde:

Ich hoffe das mir jemand bei diesem Problem helfen kann, ich komme selbst einfach nicht drauf.

Asrock Q1900M: Unexpected Realtime Delay, but Good Latency Values

Category: General LinuxCNC Questions

So i bought a Asrock Q1900M to replace a failing c2d machine, since i have this board in a nas and it gets good latency values.

Unfortionatly despite the good values, see attachment, running linuxcnc gets an instant Realtime Delay error. I am running a 45us base period and a 1ms servo period.

The test below was run with some glxgears 2 dd's for io and a wget to load network. I cant seam to repoduce any latency excursions with the latency tests.

Any ideas?

hello guys
i am trying to implement the CARSOUSEL for my ATC , i am using ethercat stepper motor for the carsousel and i found there are multiple types of encoding which actual i dont understand the difference between them. i have 10 pockets and if there is an simillar configuration to mine that i could understand from it would be perfect!

I've noticed that the only difference really with latency is having a trimmed down kernel configuration with ALL of the debugging and security options disabled, but one of the things I'll be making to the kernel is using the -O3 flag as well to maximize the performance of context switching:

www.phoronix.com/review/linux-kernel-o3/5

"Out of all the benchmarks carried out, the Stress-NG context switching benchmark reported the most significant gain out of the -O3 optimized kernel build."

Context switching can impact latency so the -O3 flag to the kernel should help, and I'll be building the kernel with LTO as well.

All of this will be hosted on the `linuxcnc` branch of my Gentoo repo:

github.com/NTULINUX/gentoo_backup/tree/linuxcnc

The release will be posted here:

github.com/NTULINUX/gentoo_backup/releases

And the installer will handle all the work for you. The installer is also designed to be installed to a USB flash drive (as long as you use UEFI, for some reason legacy doesn't work off USB but it could just be my motherboard.)

Installer is here, but it's out-of-date:

github.com/NTULINUX/gentoo_backup/blob/linuxcnc/installer.sh

And here's the wiki for everything:

openlunchbox.com/mw19/index.php/HOWTO:_Gentoo_for_LinuxCNC

The installer works on Debian too but you must be running Bookworm or newer (sid or testing)

And if you're using Debian Bookworm with a PREEMPT_RT kernel but want to use a UEFI installation, you must have `efi=runtime` specified on the kernel command line, or simply use a non PREEMPT_RT kernel when running the installer.

I'll be making a few announcements once it's finished.

One more thing, Debian formats drives in really weird ways so the installer is designed to wipe out and handle partition all by itself (partition sizes are asked during the script as it is interactive) but it uses the whole disk by design, so grab a spare hard drive, NVMe or USB drive that you're happy wiping out and use that for the install. I'll be updating the wiki as well.

I'd be truly surprised if somehow Clear Linux is faster than the image I'll be pushing out the next week or so. Also, the Gentoo installer/image is free of SystemD.
