kernel for ethercat

Category: EtherCAT

Yes I understand, but I already have some machines with Debian 10 and I have no problems. Wanting to continue with Debian 10, which is the most stable Kernel of the 4.x series.
Is it possible to use the 5.x kernel?

Thanks

OT - In the context and spirit of "IN & OUT" here's a cool 8-ch part ya fpga boyz may find useful. Considering the cost per-IO on fpgas, it's occasionally advantageous to have them bidirectional on their equally expensive hardware. Example below:

Does anyone have a better name?

1. LinuxCNC-RIO <
2. RIO
3. RIOCORE
4. Really Important OS

The enclosure was spontaneous and meant to illustrate the end goal for the protruded 90deg connectors. Just sketched a rectangle with 4 tabs, extruded it, cut off around the solids and branded it RIOCORE without thinking half-a-second (<-- birth defect). Really did took 3min from start to screenshot. ps. I'll admit I kinda like this RIOCORE though... sounds hardcore as it is!

Thanks for pointing out. Yes I have not set these.

Just Added these in ini file. And it worked.
Thanks a lot. I was struggling for this for so long.

Is it possible /etc/default/irqbalance is not being used and thus not reaching our lcnc_irqbalancepolicy.sh file? I don't understand how that process is supposed to work...

Just a guess but you definitely  do _not_ want a gateway (or DNS)

Well, that was at the time as I cut the MEesa eno1 connection in purpose to be in internet and coming into the forum to write my post.
Eno1 has a fixed IP in network manager:  10-10-10-10 MEsa resp. -2 for Intel Card.
The connection eno1 does not have an ip adress in that state. Here is an ip a with both states. Upper feedback is with connection active, lower lines without.

 

Content of /interfaces is commented out except the loopback:

Category: General LinuxCNC Questions

Hi! 
I am working with a custom ethernet interface and think I really need this IRQ management. Unfortunately I have not been able to get what's described here to work after quite a few hours beating my head on the desk and rereading ALL these posts several times. I've tried a number of things but I don't know much about scripting. I'm probably missing something obvious.

If someone has debugging suggestions or can tell me what other information to post here I would really appreciate it.
Architecture: x86_64
CPU(s): 8
On-line CPU(s) list: 0-7
Thread(s) per core: 2
Core(s) per socket: 4
Socket(s): 1
NUMA node(s): 1
Vendor ID: AuthenticAMD
CPU family: 23
Model: 17
Model name: AMD Ryzen 5 PRO 2400G with Radeon Vega Graphics

The obvious things:
I did install irqbalance via Synaptic. I did change IP to 10.0.0.1 two places in rt_setup.sh--that's the address in interfaces file.

What happens:
If I run rt_setup.sh it says it is creating the affinity file, and it ends up in /etc/linuxcnc as expected with permissions correct. But after restart I seem to end up with ethernet interrupts always on cpu5 where I would expect cpu7.
user1@debian2:~/linuxcnc/irq-mgmt$ sudo ./rt_setup.sh
[sudo] password for user1:
Linux debian2 4.19.0-16-rt-amd64 #1 SMP PREEMPT RT Debian 4.19.181-1 (2021-03-19) x86_64
GNU/Linux irqbalance is running AND there are more than 2 cpus - setting up policy script

The script comes up with isolcpus 6,7 in grub, which is what I determined months ago and added manually and seems like it should be correct.
    linux    /boot/vmlinuz-4.19.0-16-rt-amd64 root=UUID=5b220cf2-b101-424f-9abb-ee2246a65503
ro initrd=/install/gtk/initrd.gz quiet
isolcpus=6,7 intel_idle.max_cstate=1 i915.enable_rc6=0

my /etc/network/interfaces (after removing commented out lines and loopback):
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5). source /etc/network/interfaces.d/*

# NEW - Lenovo Ryzen desktop PC
allow-hotplug enp8s0f0
iface enp8s0f0 inet static
address 10.0.0.1

Significant things I tried:
Running test script "pinirq_2024-05-12.txt" with parameter enp8s0f0 displays expected results. But watching interrupts stills shows the nic IRQs on cpu5.
user1@debian2:~/linuxcnc/irq-mgmt$ sudo ./pinirq enp8s0f0
Cores: 8 Old CPU Mask: 0020 Set device enp8s0f0 IRQ 61 CPU mask to 0128

I tried using NIC=`enp8s0f0` in place of both awks in rt_setup.sh but that does not work either (note the quotes I used!).

I did have loopback lines and old (commented out) iface and address lines in interfaces file. I removed them and reran everything as I'm not sure how picky that grep is.

Retrofitting a small bending machine

Category: CNC Machines

Hi
seem to have stumbled into a little project.
 

I have already retrofitted my Maho MH500 and a cycle lathe to Linuxcnc
retrofitted, which is why a friend has now asked me to have a look
to have a look at his bending machine.

The press was probably retrofitted to a newer control system.
However, it has now stopped working and when I switch it on I get the error message

"WARNING LOST VIDEO TABLES"
 


if I google this I only find 3 forum entries, but without any answer or even a solution.
I can't say whether the controller is broken or "just" lost the programming or parameters...

In any case, I now need a replacement.
A simple 3-axis positioning controller.
The controller would only have to control 2 stops and the press stop.

all 3 axes have analog -10/+10V drives
there are probably 3 encoders somewhere for the position feedback
and that's about it.

I don't need cycles and bending programs.
If we get the 3 axes into the desired position via the control system and
then operate the press hydraulically as usual is enough...


If the machine were in my shop, I would say
Linuxcnc Raspberry, small TFT mesa card and I operate the thing via Gcode in MDI.

Maybe there is a simpler standalone solution?

So eno1 does not have an assigned IP address

What does /etc/network/interfaces contain?

Ok, we stay with 3.40. Those two different test pc have own power supply. Both are 650w and different brand.

You must identify how the EStop is exposed by the MPG. There is nothing about EStop in the mpg.hal file above. You may have to consult the MPG manual. It may be exposed as a signal you can add to the mpg.hal file, or it may only be exposed as two or four wires (which you must wire as a hardware-EStop.)

Your .hal file also does not have any entries for EStop. You'll need to use the .hal command 'net' to link it. How the 'net' command works: linuxcnc.org/docs/2.5/html/hal/basic_hal...#_net_a_id_sub_net_a

Once you figure out how your EStop button works, it would be best to find a similar setup: duckduckgo.com/?q=linuxcnc+estop+net

No beta, might have bugs.
Are you using the same power supply for all those boards?
If yes, change the power supply.
