Need to install newest Linux Debian Bookworm with the newest Linuxcnc preempt-rt

Category: Installing LinuxCNC

Hello,
I've been trying unsuccessfully all weekend to get the latest Debian Bookworm with the latest Linuxcnc preempt-rt up and running. Since I have little experience with Linux, I'm reaching my limits. 
I downloaded and installed Debian Bookworm 12.13. Now I wanted to follow these instructions linuxcnc.org/docs/html/getting-started/g...th_preempt_rt_kernel , point 7 (with preempt-RT kernel). Would that be correct so far? 
At point 3, Open Applications Menu > System > Synaptic Package Manager, search for linux-image, right-click on the original non-rt, and select Mark for Complete Removal, I don't know which original non-rt I have to select. I have attached a screenshot.
Otherwise, please attach Linux terminal commands so I can quickly achieve my goal.

Greetings from Germany and many thanks.

Hello everyone, we've now integrated several pushbuttons and switches. The signals are being received and are functioning correctly. However, a new problem has arisen: as soon as I switch on the machine, the X and Y axes start moving immediately, and Linux CNC goes into error mode. I don't recall ever having this problem before. Nothing has been changed in the wiring. Perhaps someone has a crucial suggestion.

Configure Mesa 7i96s and pktuart with Omron MX2 (wj200)

Category: Advanced Configuration

You might try increasing the interval (it's in microseconds so 1000 is just one ms)
And that may be too fast for the Omron

I will look into getting a MX2 to try to have some way of duplicating the issue.

OK 
I have given up on making it work after messing up several versions of my hals and inis
Instead i now want to make new ones by using mesaCT like i did from the beginning (the way that so far let me get the most successfull result)

I get an "OK" when trying to test the configuration
But when building the configuration i get this message from meseCT:

File "../../usr/lib/python3/dist-packages/libmesact/buildconfig.py", line 61, in build
    parent.updateini.update(parent, iniFile)
  File "../../usr/lib/python3/dist-packages/libmesact/updateini.py", line 135, in update
    self.update_key(item[0], item[1], item[2])
  File "../../usr/lib/python3/dist-packages/libmesact/updateini.py", line 765, in update_key
    start = self.sections[f'[{section}]'][0]
            ~~~~~~~~~~~~~^^^^^^^^^^^^^^^^

KeyError
'[MESA]'

First download the deb and reinstall
to be sure you have the latest build date

Then please file an issue at
github.com/jethornton/mesact/issues

socket raw Eth.

Category: Computers and Hardware

Hello everyone. Who has ever worked with socket raw on linux cnc? raw socket requires a set cap, does it break Linux Cnc? I wrote a test driver, on raw socket, receiving data via mmap. As a controller, I use STM32F7 (4 PWM encoders). Maybe I'm doing something wrong, I don't understand the specifics of Mesa, but the first tests show some kind of prohibitive bandwidth, the jitter is lower than on mesa.

Lenovo T14 Gen2 AMD - CRAZY High Latency - Am I screwed?

Category: Computers and Hardware

Ill try the other release and see how it shakes out. Its killing me because I see the T470/T480 in use in that thread and this is just the newer version of that laptop. Also I figured I was safe because this one can be bought from Lenovo with Debian preinstalled.

Sorry to clarify the bios is not password locked its just extremely limited by the manufacturer. Locked down in terms of restricted to basics.

Technical questions about CIA402 and homecomp.comp on A6

Category: EtherCAT

Hi,
I have some technical questions about CIA402 and homecomp.comp
First of all, which version of homecomp.comp is currently recommended for the A6?
Since I don't understand the source code of homecomp.comp and CIA402, I would like to know how the basic servo homing process works.
Are all servos put into homing mode and checked to see if they are ready before the sequence starts?

I'm trying to understand how the process works, as I keep getting sporadic errors during homing, even though everything else is running smoothly.

Does the drive run away if the input from the Mesa is disconnected? Do you have the manual for the drives? On my Indramat, you are supposed to turn the drives using a simple power supply, before connecting them to the controller. Sorry I am no help on this, as the PID tuning I suck at.
Cheers,
Mark

Linuxcnc erste Schritte und erste Probleme, NVEM und Remora

Category: Deutsch

Hallo Mario,

Es freut mich zu hören das Du ein Schritt weiter gekommen bist. Gut hast Du Geduld und mehrmals versucht die Firmware zu flashen!

Ich komme selber auch von GRBL; die Software ist zwar genial, aber irgendwann war ich begrentzt mit TMC5160 Treiber. Ich habe dann ein Komponent für LinuxCNC geschrieben (bin nicht mal ein Hobbyprogrammier) und es funktioniert nicht so schlecht. Es ist krass was es auf LinuxCNC alles gibt und möglich ist, im Vergleich zu GRBL. Aber die Komponenten die nicht mit der Standardinstallation kommen sind halt auch nicht unbedingt häufig verwendet. Remora ist zwar eher gut dokumentiert, es ist aber nicht vergleichbar mit Kommerziellen Produkte wie Mesa Karten zum Beispiel. Mir ging es so, und ich kann mir vorstellen das ich nicht der einzige bin: ich habe mir ein Komponent geschrieben und eigesetzt, auf github geladen und bin dann zum nächsten Projekt gegangen, obwohl der Komponent weit von perfekt war und kaum dokumentiert ist.

Allerdings lernt man viel dabei und so lange Du weiter kommst und auch hier Hilfe findest wenn es nötig wird, bin ich überzeugt das Du viel Spass haben wirst mit LinuxCNC.

Gruss,
Luca

Hi,
anhand deiner Hal denke ich, du sprichst deutsch.
Zunächst: Welche Vorlage hast du für die Konfiguration genommen?
In der ini sehe ich folgendes
1. Für die Verwendung des Handrades musst du noch die Makro buttons mit rein nehmen (müssen nicht belegt sein), sonst gibt es Fehler.
In die hal muss dann folgendes rein: loadusr -W xhc-whb04b-6 -HsfB

2. Es gibt keinen CIA402_HOMING_METHOD=-4 
Schau in die Dokumentation vom A6, da werden alle möglichen Homing Methoden aufgeführt.
Es gibt hier auch keinen Drehmomentbasierten Homing Modus. Du kannst aber einen Endschalter + Z-Impuls nutzen.
Der Endschalter muss aber dann am Driver angeschlossen werden (Di1;Di2)
Wäre zum Beispiel -1 oder -2 je nach Verfahrrichtung.
In der ethercat-conf.xml ist es empfehlenswert sync0Shift="0" zu setzen

On my machine when 19k1 is latched it fires the coil on 7k1
Then this allows 24v to the rf pins on the indramat drives. 
E1 and E2 which are +10v -10v inputs are connected to Aout0 and gnd on the 7i97t with the shield connected to the gnd as well
Bb and bb also have not been touched as they are controlled by 7k7s coil
In tommylights servo wiring and tuning how to guide he talks about wiring the drive enables on the mesa card but I think I should touch the original maho logic???? But would love to hear what you think

I spent some time going through the manual and making sure the encoder calculations are correct in the ini
I’ve done something wrong somewhere and I don’t know where?  thanks for your time paul
