Using a rotary encoder for Homing A-Axis on 7i96s

Category: Driver Boards

Ok that makes sense basically, I only really need it to use like a limit switch, so I only need the index signal to home it. Thanks

Did you follow the surface map read me instructions and copy over the subroutines? Those are what set the var file parameters for surface map page

I'm not super familiar with surface map, but I would guess it's because the bar doesn't have those parameters or the subroutines that updates the bar have those and needs to be updated.

"KeyError" suddenly appears after moving a limitswitch

Category: QtPyVCP

I've got nothing, I've not seen that write and cannot produce it here to troubleshoot. I would update to the develop branch and update your config files. Start there so at least we know you're on a known working version.

linuxcnc 2.9.2 (live) on the intel n100 cpu

Category: Computers and Hardware

It's been a while, but please allow me to post a little update on my experience with N100 based systems. I noticed that sometimes my mini-pc completely freezes, while running my mini-PC with Windows 11 never caused any problems. So the fix that I implemented was simply to ditch Debian and run LinuxCNC on Windows 11. 
Okay, all jokes aside..... After struggling for quite a while and running all possible checks, I finally discovered that the mainstream Debian 12 and 13 (Trixie) kernels, drivers and firmware have some problems with Alder Lake processors, especially the iGPU part. This can easily be resolved by upgrading Debian with the latest RT kernel (6.12.33+ at this moment), drivers and firmware. Ever since, my system is rock solid. I am using isolcpus=2,3 and irqaffinity=0,1, which gives me a responsive system with with a servo thread latency of 26.3us and a base thread latency of 40.1us, which are both excellent. This was measured during several hours, while simultaneously running 10 instances of glxgears, playing Youtube videos and stress testing the system with:
$ sudo stress-ng --cpu 4 --vm 2 --hdd 2 --fork 4 --timeout 7200s

 

Here is a brief summary of the upgrade process, for those who may be interested: 1. Enable backports:
    Edit /etc/apt/sources.list and add:
    deb deb.debian.org/debian bookworm-backports main contrib non-free-firmware
    Then:
$ sudo apt update

2. Install RT kernel:
   
$ sudo apt install -t bookworm-backports linux-image-rt-amd64 linux-headers-rt-amd6

3. Reboot and check Debian is running the latest RT kernel:
   
$ uname -a

4. Update firmware:
   
$ sudo apt install firmware-linux firmware-linux-nonfree firmware-misc-nonfree

5. Update Mesa drivers (iGPU):
   
$ sudo apt install -t bookworm-backports mesa-vulkan-drivers mesa-opencl-icd libgl1-mesa-dri

6. Check setup:
    – RT kernel:
$ uname -a
(already done at step 3)
    – Mesa version:
$ glxinfo | grep "OpenGL version"
    – Firmware:
$ dmesg | grep firmware

Mesaflash is not able to find 5i25

Category: Driver Boards

He did use sudo, I expect this is a BIOS issue, and it appears that the
hm2_pci driver works around this with this:

    // NOTE: this enables the board's BARs -- this fixes the Arty bug
    if (rtapi_pci_enable_device(dev)) {
        LL_PRINT("skipping AnyIO board at %s, failed to enable PCI device\n", rtapi_pci_name(dev));
        return failed_errno = -ENODEV;

But I don't see any equivalent code in mesaflash (nor do I know the equivalent
of rtapi_pci_enable_device with the PCI library that mesaflash uses, but I can take a look.)

At the error, remove the USB device and wait 5 seconds, insert again the USB and wait 15 seconds, click on YES and next.
Usually that works for this, well almost always.
In case it does not work for you:
Download and install Linux Mint Debian Edition, update and upgrade, then
sudo apt install linuxcnc-uspace
-
Warning, this might not be the best option for parallel port use as it might end up with quite high latency.

Hello, I'm building a small CNC milling machine. The iHSV57-30-18-36-EC driver caught my eye. Since I have no experience with Linux, I struggled to get the motor running. However, the motor jumps slightly and irregularly. If you happen to have a working ini, hal, and xml file for this motor, could you help me learn from it?

Hi, sorry for the late reply but I was travelling.
I havent run any updates since I installed PB (never change a running system). 

What exactly do you want me do double check?

This is my config..

Looks like installing LinuxCNC isn't as easy as installing a casual linux.I remember I had to burn DVD when I first installed it and I borrower a DVD drive to install it properly.I flashed the image using Rufus 4.7 and booted from the USB flash drive - but  then the setup mentions "your installation media coultn't be mounted". Is this a known bug? What's the workaround?Also I was unable to set the BIOS to UEFI mode only. There's no option to disable the compatibility mode - so setup outputs warnings when using USB flash drive in EFI mode.
