weird behavior: homing X messes up Y

Category: EtherCAT

You add a new pdoentry for 606C to the 1A00 PDO in your ethercat-conf.xml file. In this entry idx, subidx, bitlen, is from the A6 manual, you chose a name for "halPin".
Inside you hal file you can then use that name. E.g. like lcec.0.X.yourname
In this example 0 is your first ethercat interface, X is the name of your slave. See "halshow" -> Pins ...

[QtDragon][2.9.4] Tool probe starts before M6 dialog "OK" confirmation was created by SanzuiWorks

[QtDragon][2.9.4] Tool probe starts before M6 dialog "OK" confirmation

Category: Qtvcp

Hi all,

After upgrading from LinuxCNC 2.9.3 to 2.9.4, I encountered an issue in QtDragon where the tool probing routine (qt_auto_probe_tool) starts before I press the “OK” button in the manual tool change dialog (M6).

This behavior was not present in 2.9.3. Previously, the probing would only begin after confirming the tool change.

I found that explicitly disabling the automatic probing behavior in the INI file resolves the issue:

ini
[DISPLAY]
AUTO_TOOL_PROBE = False

This stops QtVCP from launching the tool probe automatically right after M6, allowing me to call the probing subroutine manually after user confirmation.

LinuxCNC 2.9.4 (Debian Bookworm)

QtDragon UI

Manual tool change with M6 remap (calling qt_auto_probe_tool.ngc manually after M6)

I hope this helps others running into the same problem.
If this change in behavior is intended in 2.9.4, it might be worth documenting.

Thanks!

Hi taloot, I am very new to CNC and am trying to setup my home made machine with QTPlasmaC. This post processor is a .doc file, Fusion is prompting me for a .cps post configuration file. Am I missing another step or something really obvious for how to load this post into my Fusion library? Appreciate any advice!

Bump to remove it from "No replies" section.
This was also posted somewhere else on the forum and replied, so this remains a test post.
Thank you.

Latency Issues - Histogram Shape

Category: Installing LinuxCNC

Not sure if base period is required to run EtherCAT, i can not recall it being mentioned from what i read on this forum.
Either way, your latency results are terrible and to see just how terrible add --show at the end of the latency-histogram line.
In short:
-If you do need base period use older LinuxCNC ISO with Debian Wheezy, does not work with Mesa EtherNET boards and might most probably not work with EtherCAT
-If you do not need base period use the latest 2.9.4 ISO, do not edit or modify anything, just install a new RT-Preempt kernel, 6.13 should do just fine
-Make a config, run the machine, see if LinuxCNC complains about anything, if not = happy machinning

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?
