Proposal RPi Linuxcnc Image Based on Raspi OS All welcome/encoraged to comment

Category: Installing LinuxCNC

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.
