It only gave me a blank page, I tried several times all day.

That's very strange as the link should not open a webpage at all since it's a direct file download link.

Should be easier to set the "double click" speed for the mouse in the mouse settings, from Linux settings.
This is from Mint, but should be similar on XFCE.

When the mdi-button is doubleclicked accidentally or just clicked multiple times in a short period, 
the mdi command is executed , mostly uwanted, multiple times. Is it possible to lock the button for
0.5 second or an adjustable value?

I have configured and installed LinuxCNC on RPI5 and I can control individual joint of robotic arm using trivkins. Using PCA9685 as PWM servo controller. Its work good. But I am strugling to get its kinamatic working. Here is photo of my arm with measurements.

I'll have a look at updating tomorrow and see how it goes.

It would appear the boot splash issue has been resolved.

Now I've looked through the threads on images and it's time for suggestions for splash, login and background images. Splash images have to be smallish PNG files.

I think those Trixie files may have been built on Bookworm, when I built an image last night it pulled the Linuxcnc packages from Debian. Trying to manually install brought up a lot of messages regarding packages that could not be installed.

DO we actually need an image anymore of the Pi is using Trixie? Why not just try one of the official Deb files here?

Now that I have a working Trixie image, one image will work for the 4 & 5 would it be useful for package building for Trixie ?

I doubt it. As of today Andy has got GitHub workflows working for all OS'es including Trixie for both AMD64 and ARM and a full complement of builds on our repo at linuxcnc.org/dists

Which LinuxCNC HW for 2026+?

Category: General LinuxCNC Questions

With newer operating systems like bookworm, there is a huge number of additional features outside of linuxcnc that affect real time and network latency. Plus the world is more complex so there is more hardware to consider. Plus the big push to power saving features has permeated everything.

If you are not using a parallel port, the old latency test is not relevant. Its all about network latency. The network is not real time but we want it to be.

Probably the biggest issue is using the wrong network driver (mainly on Realtek NICs), followed by NIC interrupt affinity. By default all system interrupts including the NIC's are placed on CPU 0 so we need to move the interrupt for your NIC to another core.  

I think this means you now need at least a 4 core CPU (eg Celeron J1900 or higher) as you need to have CPU 0 for the system and a core for the NIC and a core for the real time servo thread.

In summary, if you are not prepared to oprimise the OS for a RT environment, stay on an old and obsolete OS and hardware.

I have had to set some register in the drive to make it use Modbus.
Could be permission problem, almost anything.
Load the modbus driver only using halrun and diagnoze from there.
Something like this forum.linuxcnc.org/24-hal-components/310...-speed-control#75848
but for your Modbus drive, not the huanyang.

Additional hardware-button for coolant

Category: Gmoccapy

toogle2nist works perfectly, but I have to change the debouncetime in the componet. it will be more comfortable if the debounce-time is changed by a hal pin
loadrt toggle2nist names=toggle.coolant
addf toggle.coolant    servo-thread

net coolant_is_on toggle.coolant.is-on <= halui.flood.is-on
net coolant_button toggle.coolant.in <= emcopanel.coolant

net coolant_on toggle.coolant.on => halui.flood.on
net coolant_off    toggle.coolant.off => halui.flood.off
component toggle2nist "toggle button to nist logic";

pin in bit in  "momentary button in";
pin in bit is_on "current state of device";
pin in unsigned debounce = 50 "debounce delay for 'in'-pin in cycles";
....

Yes, I tried to download it here.
It only gave me a blank page, I tried several times all day.
In the evening, I left the blank page open and after 10 minutes, I refreshed the blank page and the download started.
I'll try with Xilinix.
Thank you very much for everyone's help.

StepConf setup of Z-Axis Home and Limit switch

Category: Basic Configuration

This was a case of needing to really dig into it "one more time" - The problem I was facing (and just couldn't see until I was documenting it all for 'You', was that the following section was also missing from my hal file:

net max-home-z => joint.2.home-sw-in
net max-home-z => joint.2.neg-lim-sw-in

At some point in the process, I thought I saw it - I don't know if I misread it (seeing either the X or Y version) or if I somehow accidentally deleted it right after seeing it, but putting it in allowed the home switch to work, and now the mill is one step closer to working.

I am having some teething issues with getting Z set up nicely (why is Z always the complicated one!?), but I think I'll get that sorted out soon enough once I dig into it tomorrow.

Although this is resolved already, I'll just leave it out here for the benefit of anyone else searching for help on this problem.

Changing starting point on 2D job

Category: General LinuxCNC Questions

I'm using LinuxCNC as part of a wire EDM, and it's also my first experience with Linux of any sort.

When I load a job, a 2D representation appears on the Preview tab and on the figure is an "X", where cutting will start. Depending upon the shape of the blank and the outline of the part, it's sometimes better to have the starting point elsewhere. Is this something that can be changed within LinuxCNC, or can it only be done in the program that generated the G-code file (Vcarve, in my case)?

Thanks
