RQ Affinity setup  was created by  rajsekhar
Hi..I am doing a machine using MESA boards.

Over last few weeks, I have overcome the computer latency issue, Many thanks to this forum. Now, max jitter comes within 40,000ns for both base thread and servo thread.

But network latency continues unless I use IRQ affinity.

I had run tests and result as follows:

with enp4s0(my network hardware) interrupt in CPU0:
===========================================
raycnc1@debian:~/Desktop$ sudo chrt 99 ping -i .001 -q 10.10.10.10
[sudo] password for raycnc1: 
PING 10.10.10.10 (10.10.10.10) 56(84) bytes of data.

--- 10.10.10.10 ping statistics ---
966462 packets transmitted, 966461 received, 0.00010347% packet loss, time 967436ms
rtt min/avg/max/mdev = 0.096/0.100/7.930/0.009 ms
^Craycnc1@debian:~/Desktop$ 
===============================================


And with interrupts in CPU1 (i.e last CPU)
===================================================
raycnc1@debian:~/Desktop$ sudo chrt 99 ping -i .001 -q 10.10.10.10
[sudo] password for raycnc1: 
PING 10.10.10.10 (10.10.10.10) 56(84) bytes of data.

--- 10.10.10.10 ping statistics ---
7762711 packets transmitted, 7762710 received, 1.28821e-05% packet loss, time 7770480ms
rtt min/avg/max/mdev = 0.048/0.095/0.267/0.027 ms
^Craycnc1@debian:~/Desktop$ 
===========================================================

Note 1) In CPU0 result, max time is 8ms almost compared to 0.3ms in other case. So IRQ affinity setting is essential.
Note 2) The affinity setup is done for test using a script from PCW, but that require manual command run after every boot, not run automatically.

So, I have failed to do the IRQ setup.

I did follow the Mozmck post. 
forum.linuxcnc.org/38-general-linuxcnc-q...ead-and-irq-affinity

The network interface file is attached. I assume it is not as per the requirement. I have attached IPV4 setup page photo for ip setting values.

Need help.

Please refer the below message

That is the solution, for the mach3 5axis BOB outputting default 9,5V (9,6V) on the 0-10V terminal! Thanks!

Das sieht schick aus. aber es sind wirklich viele (10) Seiten. hast du auch eine Art Handbuch dazu geschrieben?

Wenn ich das richtig verstanden habe, werden die Koordinaten nach einer bestimmten Zeit gespeichert und nicht auf Knopfdruck?
Habe ich das richtig verstanden und kann man auch Kommentare dazu schreiben?

Hello,

i want to control the feed speed with a potentiometer on a 7i96s mesacard.

i dont know how to do that. 
Can anybody explain me, what i have to do?

Thanks in advance.

Seems to come from here:

 

There should be more information printed if you start your config from a terminal

You have not configured any joints/axes in your ini file.
Seems that you may have missed to add them in the configurator:

 
 

 

Vielleicht hilf dir das hier weiter:

Hallo zusammen,
 im Rahmen meines aktuellen Projekts muss ich eine Automatisierung simulieren, bei der ca. 2800 Punkte angefahren werden. Die Koordinaten dieser Punkte sind mir derzeit nicht bekannt, daher muss ich sie zunächst manuell mit einem Joystick anfahren und die Positionen anschließend dokumentieren.
 Um diesen Prozess zu vereinfachen, möchte ich eine Möglichkeit schaffen, die aktuellen Maschinenkoordinaten automatisch in eine Datei zu schreiben, sobald ich einen Punkt angefahren habe. Idealerweise soll dies über ein Tastenkürzel oder einen speziellen Button erfolgen, um das manuelle Abschreiben der Positionen zu vermeiden, was bei der Menge an Punkten sehr zeitaufwändig wäre.
 Gibt es bereits eine Lösung oder ein Tool, das eine solche Funktionalität unterstützt? Ich bin für jede Hilfe oder Anregung dankbar.
 Vielen Dank im Voraus!

There is no cia402 module installed, see how to install it, or if it should be installed with EtherCAT.

There is no PyQT section, do you mean QTVCP or QTPyVCP?

Back in the RPI3 days, it was to weak for some stuff, then RPI5 came out and a mess ensued with 7 versions of hardware and missing drivers and SPI still does not work.
Then the price went to over 180$.

Hello Peter,
In trying to get another couple of axes integrated with my mill, I seem to have killed my 5i23 - currently not found by mesaflash --device=5i23 --readhmid.

I stupidly unplugged the cable from a 7i52 to a stepper driver (which was unpowered) without powering off the system. I'm not sure if there's anything I can do about that short of buying a permanent replacement card for the mill, but in the meantime I need it back up and running and have 2x 7i80HD cards, one -16 and one -25 I can use.

I'd be grateful if you could build a firmware for me for one of the 7i80s that can support my config:

loadrt hm2_pci config="firmware=hm2/5i23/5i23_fmd.bit num_encoders=14 num_pwmgens=7 num_stepgens=2 sserial_port_0=1"

Currently this is for a 7i48 driving 6x +/-10V motors (4 servo, 2 spindle) and 6 encoders; a 7i52 with 1x sserial port (to 7i84), 2x stepper motors and 2x encoders, with space for one more pwm and 4 more encoders (for a future atc if anything).

thank you - also any advice on resurrecting the 5i23 gratefully received.

Looks like it came from the factory with it, cool!

If i understand this correctly, you need the configuration folder, not the GUI, so that is usually in the /home/user_name/emc2/configs for 2.5 version, just save that to a usb.
Then you can start that config by right clicking on the .ini file and choosing 'open with' then typing 'linuxcnc' and OK.
