iopl() is a system call required to gain access to privileged resources.
It is unclear whether the user has attempted an install from the Linuxcnc ISO or from a vanilla Debian install with a self built kernel or via package manager. Neither is it clear whether this is a RIP install of Linuxcnc or via a package.
If the OP can clarify these items and if self installed give a source for the instructions or elaborate on the process this would be great.

Blindly giving advice such as "reinstall" or redo this or that is the advice that is very common to the "Windows Ecosystem". As ethical Linux users it is far better to establish what the actual issue is and then make recommendations.
Even if one does suspect a corruption of the installation media it would be of great value to suggest, and advise the user how to, check that the ISO is a good download.
Tommy's advice regarding rebooting is a good suggestion regarding a previously "hung" Linuxcnc session.

So once we establish the user's method of install we can hopefully forment a solution.

try a mode change: mdi to manual back to mdi.
It forces the vars to be saved to file.

This mainline build also works pretty well, but will first do some more testing. In chromium/firefox the acceleration doesn't work, but 1080p works fine though. I'll upload an image/kernel if someone is interested.

 

When I configure a key as in hal Pin with 0, they are effectively created as hal pins, but when checking by running linuxcnc when pressing the keys related to those hal pins they do not change state, which would indicate to me that they are not connected. When testing from Arduino through the serial monitor, pressing any key shows that it is activated.

You are not the only one. I am using qtpyvcp and I am working on a workaround that will comment out the preceeding T lines and replace it with some special chars like (xx T1 M6) when RFH issued and save. And when a run command issued, it would remove and save. I am not sure how possible this is but I have some similar tricks in python before on qtpyvcp.

You should select 7I92 internal data and 7i77x2 as shown
then accept component changes. Here's what I get:

Before "Accept Component Changes":

 

After "Accept Component changes":

 

P2 setup (mainly encoders):

 

PWM (analog out) setup:

 

pncconf does have a known bug with some locales so that may be the issue here

Hello everyone!

I'm new at the LinuxCNC Software and trying to figure out how everything works. But now I'm stuck at the PNC Conf Wizard and don't know how to get through there.

But First:
I'm using a HP Elitedesk with the Linux CNC Distribution (2.9.4), a MESA 7I92TM connected via Ethernet and a 7i77 at Port P2 for the Servo Drive Control. My Servo Drives (Yaskawa SGDV-7R6A01A) should run with +-10V and Encoder Signal to the Linux CNC.

My Problem: I'm stuck at the right config for the card and the control. Witch selection should i use?
7i92-InternalData ? -> there i can choose the Firmware for a 7i77 but the config at P2 is a little bit less i think...
7i92T ? -> At the P2 config i have to choose a card like 8i20 or some others, but i don't have more Mesa cards...

Witch config i should choose and what should i take in the P1 / P2 window??? If i don't choose anything the Conf Wizard shows me a problem (Config_result.png)

Attached you can find some pictures of my config struggle..
Thanks a lot and all the best wishes from Germany

Hallo, ich habe Die gleiche Maschine wie Du gekauft. wie weit bist Du mit Deinem Umbau? Welche Servos hast Du schlussendlich verbaut? Woher kommst Du?

Hi Markus,
Sorry wegen der späten Antwort. Ich bin mitllerweile relativ weit, für zwei Sachen hatte ich noch nicht Zeit, das Einbinden der Glasmaßstäbe und die Getriebeschaltung. Momentan habe ich immer den höchsten Gang drin und nutze einen Frequenzumrichter. Ansonsten läuft die Maschine. Ich habe noch zwei Gasdruckfedern zum ausgleichen vom Gewicht des Tischs eingebaut. Die Servos sind billige China-Servos (S2 Series steht da drauf, gibts billig auf Ebay), wobei ich vielleicht nächstes mal eher bei Stepperonline kaufen würde, da die Firmware buggy ist. Ich komme aus dem Allgäu, also nicht weit weg

The developer took pity on me and sent a stripped down version of his initialization code. It fails in exactly the same way. Maybe I'm doing something really fundamentally wrong, except that since the arc generator boots up successfully to OP makes me again suspect that the ECT and ECR models differ in some way not documented. This could explain why the developer - who know the system and code inside and out - can't get it working either...

Oh, as a sanity check, I swapped in a brand new ECR unit that's never been run - same issue.
Is there any way to request the error code from the slave via a Geany terminal, to have the system tell me why it's unhappy?

Hallo zusammen,ich habe einen Servoregler ERL PCSE200 ext. M24.42E PLE60-40 
Die Steuerung erfolgt normalerweise über CANopen, ich würde den Antrieb aber gerne über Step/Dir mit meiner Mesa 7i96S in LinuxCNC ansteuern (da ich noch weitere Achsen so betreibe).Am Gerät befindet sich ein 26-poliger Sub-D-Stecker für die Signale. Leider habe ich bisher keine Dokumentation zur Pinbelegung (STEP, DIR, ENABLE, GND, Versorgung etc.) gefunden.
Ich habe den Hersteller ERL bereits kontaktiert, aber vielleicht hat hier jemand im Forum die Unterlagen oder praktische Erfahrung mit diesem Regler.Besonders wichtig wäre für mich:

• Welche Pins sind STEP+, STEP–, DIR+, DIR–, ENABLE?
• Welche Logikpegel erwartet der Regler (5 V TTL oder 24 V / differenziell)?

Fotos vom Gerät (Typenschild, Anschlüsse, Platinenrückseite) kann ich bei Bedarf hochladen.Vielen Dank schon einmal für eure Unterstützung!Grüße Jochen

You can use a fast encoder for a MPG but one disadvantage of this is that fast encoders do not
support 1X mode, so if you want 1 increment of motion per MPG click you need to use the MPG encoders

langdons: It's an old PC from a sale for 10 euro - I don't know the type

PCW:
yes, inputs common is 5V GND ( TB4 / pin 7 GND  - is Stepmotor GND = power GND) - is sinking inputs

MPG wheel signal output are connected to ENCODER 4 (TB 2 / IN 9-13) and is configured in PNCONFG as MULTIHAND Wheel (foto) 

7i95T board has 6 fast (10 MHz) encoders, and 4 slowly encoders (TB6 / IN 0-7) which I left free.
I don't know if it can work like this, or if I have to connect the MPG wheel to the TB6 / (IN0/IN1,IN2/IN3,IN4/IN5.IN6,IN7)

Probably from the vfd module github.com/gitcoffey/l510_vfd/blob/c4e57...bd16/l510_vfd.c#L206
 

Hi, Here you can find a few rt-kernels:
drive.google.com/drive/folders/1JglCIPKv...roZcjOvr?usp=sharing

With the 6.1.115 kernel I'm still experimenting a bit to get full gpu acceleration, I think the 6.1.75 is a more safe choice. Then find/create an image from Armbian for example, install the kernel and the dtb of the same kernel version. Check /boot if the symlinks are correct, sometimes when it creates a new initramfs creates a link to the older version, so better to delete or move the other kernel versions to a another place.

With Armbian: when you choose for an image with Debian it's more easy to install LinuxCNC but you probably won't have VPU acceleration (1080p/1440p still works fine though)
With Ubuntu it's more easy to have VPU acceleration, but you'll have to compile LinuxCNC yourself (there's a manual).
With the mainline kernel you should expect that not everything works yet.

So make your choice, find download an image that fits to the kernel you want (Vendor 5.x or 6.x) or mainline. Install the kernel and dtb if it's not exact the same version.

For better latency values isolate the last core (isolcpus=7). With Armbian edit the extraargs line to add the kernel parameter:
sudo nano /boot/armbianEnv.txt
extraargs=cma=256M isolcpus=7
ctrl+x and press y following an enter to save.

In Debian to install linuxcnc:
sudo apt update; sudo apt install linuxcnc-uspace

Hi all
i want to understand is it possible to do machine on linuxcnc as main controller, which will do next things:
Operator put bar of 1.5mm*40mm coper into machine. On received signal ready from button, and going to gcode commands like g01x100 moving bar. After on the command M10 do punch of O-shape hole, next moving to next point g01x250, next triangle punch hole -  M11. Next g01x400, and command M20 cut a piece. 
my question is -
1. somebody already try this king of production?
2. How to do cyclic feeding in long gcode, i mean that i have not the same lengths and different punch map on each bar, i have program for example on 10 bars for repeating.
3. How cnc receive command to return x axis back to zero and let user to put new bat in?
4. What is the maximum length of axis? For example if i will use reel , not bar.
5. I will glad to read some ideas and additional questions about topic)
