Bonjour à tous.
voila mon PB, J'ai une carte Digital Dream EC300 flashé en remora, un grand merci à Scotta pour son travail.
J'ai branché un MPG simple, avec juste 2 sélecteurs (échelle X1,X10,X100 et X,Y,Z,A) et une molette de jog.
Mon fichier jog.hal est celui de la doc linux cnc adapté avec mes entrées.
Linuxcnc 2.9.4 démarre bien. Je peux déplacer les axes avec le clavier, mais rien ne se passe avec le MPG
Je précise que dans Watch Hal les variables axis.y.jog-count, axis.y.jog-enable, axis.y.jog-scale réagissent bien avec les sélecteurs
c'est pareil avec les autres axes.
ci joint une photo des variables pour l'axes Y. 
J'ai tenté de forcer avec un set, pas de déplacement de l'axe.
Il me manque quoi?
Je ne suis pas un spécialiste en linux, j'essaye de migrer ma cnc de mach3 à linuxcnc.
Merci

you might have to use the 'not' component:

loadrt not
addf not.0 servo-thread
net your_signal not.0.in
net your_signal_inverted not.0.out

Hello,
i just try to complete the function in the attached file. My postgui.hal:

#[Startknopf]
loadrt or2
addf or2.0 servo-thread
net Start.ext.an <= gladevcp.Start => or2.0.in0
net Start.ext.an1 <= hm2_7i76e.0.7i76.0.0.input-04 => or2.0.in1
net Start.or <= or2.0.out => hm2_7i76e.0.7i76.0.0.output-05 => gladevcp.led_Startstopp => halui.machine.on

#net Start.or => gladevcp.Start-not => hm2_7i76e.0.7i76.0.0.output-06 => halui.machine.off
#net Start.ext.aus => gladevcp.Start-not => hm2_7i76e.0.7i76.0.0.output-06 => #halui.machine.off

I can´t get output-6 and halui.machine.off to work.
Please help

Thanks, that works

The Linuxcnc-RIO\riocore has a max6675 plugin.

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

Don't you also need to regulate the temperature via a relay that controls a heating element of some sort?

I guess it really depends on whether the OP is better with computers and software or discrete components.

A comparator and a 555 timer, adjusted by a potentiometer would suffice.

One of these could be useful (though they might just be total worthless garbage, it's hard to tell):

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

I feel I overstepped my position and would like this topic deleted.

Huh?

WTF?

Why?

Coordination is a good thing always, all LinuxCNC stuff should be in the official LinuxCNC repo, not some random offshoot side project fork.

It might be easier to have a separate, dedicated, thermostat-like device for the temperature.

Simple on-off stuff does not need the "brains" of a pc.

You can use a regular thermostat if you somehow "fudge" the sensor impendance.

Perhaps someone has adapted QtDragon for this purpose or something.

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

                          
Holen:7 https://www.linuxcnc.org bookworm InRelease [31,1 kB]                
Fehl:7 https://www.linuxcnc.org bookworm InRelease

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.
