The Linuxcnc-RIO\riocore has a max6675 plugin.

github.com/multigcs/riocore/blob/main/ri...ns/max6675/README.md

That doesn't always happen.
I used to distribute an ISO based on Mint 19.x & build packages for installation via apt.
Tommy has a later Mint based ISO, if memory serves me right.
There has been a couple of Raspi OS based images for the RPi platform as opposed to the Debian based image that forms the official image.

The code base used to build the current image is a fork from the linxcuc live-build repo.

In another thread I posted links to test images, based on my findings regarding the raspi-firmware issues, unfortunately no one, it would seem, downloaded and was able to test the images. It was clearly stated that they were test images only and not to be used for a production machine.

I did state in my initial thread that I wanted to open a dialogue with regards to building a new 2.9.x based ISO.

Machine Kit was a fork of Linuxcnc, worked well on a lowly powered BeagleBoneBlack (1Ghz & 512MB ram) and was able to use the in built micro controller for step & direction generation worked quite well on a 3 axis mill, unfortunately development on that project stalled.

@langdons "not some random offshoot side project fork" . Oh the irony.

For isolcpus:http://wiki.linuxcnc.org/cgi-bin/wiki.pl?The_Isolcpus_Boot_Parameter_And_GRUB2

For pinning the IRQ there is a script for testing here: 

 

to run, first download the script then:

chmod +x pinirq.txt

then

sudo ./pinirq.txt [ethernet_device_name]

 

Can you explain how to do it?

Now I just need to configure the INI to mm and the speeds. I'm getting errors from

hm2/hm2_7i965.0: stepgen.00.maxvel is too big for current step timings & position-scale, clipping to max possible

Another cheap option for reading thermistors is LM331, a voltage-to-frequency converter

Or an industrial solution by Mesa, the THCAD

Hi,
I used Debian 12 LinuxCNC image to install LinuxCNC. Afterwards I updated to Debian 13 as shown here in the forum

The "bookworm" there should be "trixie" You need to change the distro name in /etc/apt/sources.list.d/linuxcnc.list

To address the key length issue (which, oddly, didn't seem to effect my Trixie installation) I have created a new, longer key and signed the trixie repository with it (I _think)

The new key can be found at keyserver.ubuntu.com/pks/lookup?search=L...gerprint=on&op=index

But the best option is probably to use a new version of the LinuxCNC install script which will install the keys then install LinuxCNC.

www.linuxcnc.org/linuxcnc-trixie-install.sh

This can be downloaded (right-click and save-file-as), made executable ("chmod +x linuxcnc-trixie-install.sh") and then run ("./linuxcnc-trixie-install.sh")

I would very much appreciate it if folk could try this out before I properly announce / release it.[/code][/quote]

Normally the DKMS 8168 driver will fix the Ethernet latency issues

If it's not sufficient, one additional step to do is to  use isolcpus
to isolate the last processor and then pin the Ethernet IRQ to that
processor.
 

I have executed this in a terminal:
sudo cyclictest -l 10000 -m -p 80 -i 1000 -q -v

He has given me this:

0: 9996: 2
0: 9997: 2
0: 9998: 2
0: 9999: 2
T: 0 ( 2995) P:80 I:1000 C: 10000 Min: 2 Act: 2 Avg: 2 Max: 7

It seems that by switching to r8168, I am no longer getting the error.

I currently have 3 axes, but I will be installing 5 simultaneous axes. Is it advisable to change the network card?

So what is it due to?

Should I change the network card?
