Thank You Andy, Im sure it was my fault, just to old and Technologically inferior to comprehend.

Great ! i have to figure out how to load the error files to a USB Stick .
The builder was a bit of a Conspiracy theorist... he had everything locked down.

Latency Issues - Histogram Shape was created by FixItWithMonkeyWrench

Latency Issues - Histogram Shape

Category: Installing LinuxCNC

Hi all,

I'm new to Lcnc, and have been for the past week trying to get my PC to hit the right latency levels.
After a week i've managed to get the base thread down from 126us to about 90us (worst case) which I've read is okay if you're using it with ethercat.

However I've noticed most of the graphs, especially for the servo period Histogram Latency graph that the shapes that most users have is a single peak. I've always been getting 3 peaks.

I'd like to confirm whether having this type of histogram shape is normal? or whether this shape indicates further sources of latency to be reduced. 

For Background:

Setup:QBiX-GLKB4125-A1 Mini -PC  J4125 Processor

I've grubbed out all i can think of to help the latency with a small amount of success to when it was out of the box

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash kthread_cpus=0,1 irqaffinity=0,1 rcu_nocbs=2,3 nohz_full=2,3 isolcpus=2,3 rcu_nocb_poll nohz=on intel_pstate=disable amd_pstate=disabled amd_idle.max_cstate=1  processor.max_cstate=0 idle=halt skew_tick=1 idle=poll cpufreq.off=1 cpuidle.off=1 intel_idle.max_cstate=0 nowatchdog nosoftlockup igb.EEE=0 apm=off nosmt=force acpi_irq_nobalance i915.enable_rc6=0 i915.enable_dc=0 i915.enable_psr=0 i915.enable_fbc=0 drm_kms_helper.poll=0 pcie_aspm=off r8168.aspm=0 r8168.eee_enable=0 mitigations=off pcie_aspm=off hpet=disable"

got the governor running on performance, and .sh to set the IRQ affinities.

disabled stuff in the bios

updated drivers via the terminal but haven't yet tried updating the NIC,Graphics, and Chipset drivers from the manufacturer.

Any help would be much appreciated, as I'm new to linux. Thanks.

Is it really bickering when correcting so much bad information from langdons ?

This is what I meant in my problem thread.

Apologies to the OP, just didn't want you to do anything that could cause issues.

You may have to check dmesg for any references to R8169. PCIe should be enabled, I used a NVMe boot drive. Remember that the location of config.txt is
/boot/broadcom/config.txt
I sure this is mentioned in the main image RPi5 thread.

Raspberry Pi Kernel recompile for waveshare 1Gbit Network interface

Thanks for the fast reply

I Downloaded 2.94 Rpi 5 based OS from the official linuxcnc/download site.

The Waveshare user guide states that something in the lines of:
Device Drivers
> Network device support
    > Ethernet driver support
       > Realtek devices
          > Realtek 8169/8168/8101/8125 ethernet support

needs to be added if not using original rpi os.
i am pretty sure that is the problem, as i see the card with lspci as described in the user guide:

 

but not in ifconfig:

 

it is also stated, drivers could be installed manually but its not recommended.
Also, there are other rpi linuxcnc distros floating around, do you think its worth switching around?

I did as you suggested. Many thanks. It worked a dream and I can still thread at 1000rpm. Going to sort my motor slow down speed as its currently two revolutions. So i have modified my ngc file for not to account for this. Many thanks again

Shouldn't need recompiling as, our images use a kernel built from the Raspberry Pi GitHub sources.
The only difference being is choosing the kernel config option for real time.
If the standard kernel doesn't work give me a yell and I'll build an update image, as there are a few minor things I would like to add.

Another "arduino io panel" was created by bobwolf

Another "arduino io panel"

Category: Show Your Stuff

Hello everyone
I was inspired to make an interface to manage a generic operator panel (not for real time operation). I saw that there are already many; mine would be a little simpler and above all easily expandable.
the first idea, which I tried on a breadboard, was to use physical pins (parallel port, mesa, etc etc) controlled by hal with an ad hoc program and with a sort of multiplexer to be able to multiply them almost at will. in theory I could reach 256 inputs and 256 outputs. even too many, but these are its potential.
then I said: let's try to put a jog wheel in the system, and there the problems came; with my system I lost too many steps and had dead times. unusable.
I began to understand if with arduino I would have had more chances of success, and always in theory, since I'm waiting for the components to do the experiments, I should have good results.

prototype features:
128 maximum inputs
128 maximum outputs
3 inputs for rotary encoders
3 inputs for potentiometers
communication with hal via arduino usb
data update time 10/20ms (50/100Hz)
for an operator panel 50/100ms would also be fine but doing the math I should be fine with the shorter times.

what could be useful to insert in this system? the first thing that came to mind would be analog outputs to drive pointer instruments or digital displays that accept 0-5v voltages, to be used to display parameters such as spindle speed, feeds, or anything else that comes to mind.

could it be a good system to develop?

ciao
