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)

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)

If the MPG common is +5V, you will need to wire the 7I95T input commons to 5V GND
Also I did not see the actual MPG encoder pins connected. These would need to connect
to 7I95T inputs that support the MPG encoder feature (IN0/IN1,IN2/IN3,IN4/IN5.IN6,IN7)

If you did not want to tie up so many isolated inputs on the 7I95T, another possibility would
be to use the P1 expansion for the MPG (with firmware that supports MPG encoders on P1)

I have looked into this in the past, and concluded that it's not particularly easy.

In your case the answer probably is to send the probed points out of G-code on HAL pins into a python routine that is monitoring them.

For a small set of values you could use one pin per value, for a larger number maybe one pin to send the value and another to indicate which parameter it corresponds to.

What PC?
Are you using a parallel port?
If yes, did you type a ROOT password during installation? This is not good as you have to reinstall and skip the root password.
And reboot the PC when you see this is the error report:

not yet tested - I'm worried that I connected it wrong - it's my first experience with MESA
I'd be happy for any comments
 

I'm not sure if I should ground the shielding of the servo motor data cables to the MESA board - the drivers are already grounded via the ground wire from the ~ 230 V power supply and a ground loop is created, which could cause EMC interference

Is that an old PC chassis?

Cool reuse of existing stuff!

Try it out and see.

So long as the E-Stop button works, you should be able to halt the machine before anything gets damaged.

       

Make sure secure boot is disabled first!


While you are in the BIOS setup, also turn off turbo and powersaving features.

Set the cooling profile to max performance or active.


Also, Windows installations sometimes leave behind system partitions that don't always get erased when installing Linux.

Try removing all traces of Windows.

However, sometimes a system can't boot Linux without a Windows system partition there for some reason, it's all quite strange.

But secure boot is pretty much always bad.

Strange.

Perhaps a corrupt ISO or install is to blame?

Try redownloading and reinstalling the official 2.9.4 ISO.

linuxcnc.org/iso/linuxcnc_2.9.4-amd64.hybrid.iso

Hopefully that should fix it.
