This also occurs with Qtplasmac. I can replicate it if I use the keyboard to jog and click to another tab while jogging. It loses focus/control even if I release the keyboard jog arrow and I have to go back to the main tab and tap a jog button again to get it to stop jogging.

Signal wire colors default to color codes representing the signal type, but can be edited. If the rat's nest is a confusing mess of same-colored wires, double-click or right click a wire to edit its color. All wires connected to the same output are synced and will change to your edit.

You can also change the wire (hal signal) name, but the current version of halflow gives you no capability to load your edits back into your linuxcnc hal config.

Also not sure about the frequency on cpu 1. The governor looks right but current freq = 400Mhz. This doesn't seem good if I understand it right. (again very new to this)

$ sudo cpupower -c all frequency-info

I'm very new to this so please pardon the questions.  I recently acquired an INTEL NUC core-i3 with 8GB of ram. This is intended to drive a MESA 7i76e board on a plasma table.  

tldr; I'm primarily curious to know if the latency results I'm getting are going to work (if that's possible to advise).

I've downloaded the latest iso and  went through performance tuning.  I *think* I've done all the things.  It's sometimes hard to follow all the different threads on tuning.

1) Turned off things in BIOS (hyper threading, power management etc.). This left me with two CPUs
2) Grub configured (including isolcpus)
3) CPU governor set to performance
4) IRQ coalescing disabled (intel NIC)
5) CPU core isolated for LinuxCNC (cpu 1) (I am not sure how to confirm this is actually working as intended)
6) Ethernet IRQ pinned to isolated CPU (cpu 1)

The latency histogram as a result looks like this (6 glxgears & running YT videos):
 

~60 us of max latency.   Is this worth continuing to try to use or should I be looking at a better computer?  Any advice appreciated.

I have not hooked it up to the machine yet to try it.  Hope to be attempting that in coming weeks.  Thought I'd post this to see if I need a different computer first.

I am aware of one or more similar projects, but they did not seem to fit my use case.

This is entirely vibe coded. I have not studied the code. I chose GPL for the code license, but considering this is an ai production, I was wondering, maybe I should change it to 'public domain' ?

Use at your own risk. This software is not for use anywhere it could cause machine damage or personel injuries.

This project is currently 'pre-release' stage. It can be installed via git from [1].
you will need to install sshpass, and have ssh access over the local trusted network to linuxcnc.

Goals of this project:

1. Visualization of the current running hal config on any LinuxCNC machine over local trusted network.
2. Editing of parameter values, signal names and values.
3. Automatic detection of loadable hal components on the running LinuxCNC instance.
4. Load/Save configuration projects within the linuxcnc/configs directory.
5. Live parameter and pin value displays while connected to a live hal system.
6. Live editing of the running hal via net, setp, unlinkp, loadrt, and related commands over ssh connection to the machine directly via interaction with the nodes in the canvas. This action will be preceded by a popup strongly encouraging the user to first e-stop the machine. This will avoid having to constantly reload linuxcnc after minor edits.
7. Still dreaming...


Of the above list:

(1.) is working on my pc.
(2.) Is working.
(3.) detects installed components; to properly detect custom components make sure you fully installed with:
sudo halcompile --install my-custom-component.comp
sudo halcompile --install-doc my-custom-component.comp

TODO: find custom python components also.
(4-7) Coming soon...

I could do that, but keeping track of the old Z might be tricky, especially if subroutines are involved.
I was also thinking that wrapping the "G0" and "G1" gcodes in a short python script (or even gcode wrapper) might work, but it would take more time than I waste waiting for the machine
I guess what I was originally asking was "does everyone else do it this way too?"

Hi All,

For my account,(under profile section) the button 'private messages' is linked to " forum.linuxcnc.org/cb-profile ".
Is that just for me, or is it not possible at all to use private messages on this forum?

Thanks in advance image missing /media/kunena/emoticons/smile.png

A bit of a strange request. I'm looking at `gcode.parse(...)` the CPython extension function implemented by `gcodemodule.cc`. It is a blocking call from the Python caller's perspective: it initializes an interpreter, opens the file, executes init codes, then loops over `pinterp->read()` and `pinterp->execute()` until the file finishes, an interpreter error occurs, or a Python callback aborts.

I am trying to benchmark a few things and I was wondering if anyone knows of a repository of g-code files for testing?. Basically I'm looking for a small set of .ngc files: small known-good, medium CAM, large CAM, arc-heavy, and many-short-segment. I could create some, but I thought I'd ask if a set already existed.

To answer a few questions,

Tommy,
The soft limits work fine after the machine is homed. The crash into the hard limit happened before homing the machine while jogging from a long distance to get close to the home switch before homing.

This is a new pc bought just a few months ago for this refit.

NWE and Rod
It is an ordinary USB wired keyboard, and exhibits no signs of physical sticking keys, (other than this issue while jogging).

I'll try the xset -r, and report back. But the problem is intermittent, and may not act up for testing.

Hello Andypugh,

This modification was really helpful in last machine I made. I'm now trying to achieve similar but Linuxcnc has changed a alot. Also changed a lot in kinematics. I tried to modify kinematics as per this thread but as expected it's failing with errors.

I want to use XZ and B axis with TCP along with tool length probing. Setup in this thread is working in older version.. I'm struggling to getit worli with Debian 13 rt 2.9.8 Any help or suggestions would be appreciated,


Thanks

Hello Aceiera,

I'm also trying to achieve similar 4Axis TCP kinematics. I want to use Rotating spindle head and XZ gantry with fixed table. No B or C axis. I tried to compile 5Axiskins by removing C axis values but not accepting compilation. Any help would be appreciated.


Thanks

You could consider adding the required magic with a Gcode filter that is applied when files are opened...
