Using POSIX realtime

Category: EtherCAT

This is interesting...
Looks the same. I changed my device to the same settings you have and it still works.
Is it a Realtek device? Which kernel module does it use? Find with the command "lspci -k" and find the network adapter.

I looked in the source code for when it rejects a device and this is what it says in the ecdev_offer() function in module.c:
* The master decides, if it wants to use the device for EtherCAT operation,
 * or not. It is important, that the offered net_device is not used by the
 * kernel IP stack. If the master, accepted the offer, the address of the
 * newly created EtherCAT device is returned, else \a NULL is returned.

There are some debug outputs that can be interesting. Unfortunately the debug attempt before failed
because the master is configured before the debug can be set in the way we tried before.
But here is a way.
First stop the ethercat server with the command "sudo /usr/sbin/ethercatctl stop".
Then copy the the file /usr/sbin/ethercatctl (it is a script) to a new name like ectl and change the line as shown
sudo cp /usr/sbin/ethercatctl ectl
# ... edit ectl and add debug_level=1 to this line a shown around line 126 in ectl

    # load master module
    if ! ${MODPROBE} ${MODPROBE_FLAGS} ec_master \
            main_devices="${DEVICES}" backup_devices="${BACKUPS}" debug_level=1; then
        exit 1
    fi

# Make executable
chmod +x ectl
# and start the ethercat master, then reset debug level to 0. It produces a lot of info
sudo ./ectl start
ethercat debug 0

sudo dmesg

Then have a look at the output, the lines around the configuration is important.

LinuxCNC compatible industrial PC was created by workshop54

LinuxCNC compatible industrial PC

Category: Computers and Hardware

Hi everyone,I’ve been looking for a suitable new industrial PC for LinuxCNC with Mesa (Ethernet-connected, 7i94), but the search is becoming frustrating.

There’s a lot of great information out there, but most recommendations point to older refurbished systems that are either no longer available here (Europe) or require a lot of BIOS tuning to get acceptable latency. I’d really prefer to avoid spending a lot of time testing different systems or diving deep into BIOS settings and latency tuning.

I’m already spending enough time figuring out the electrics, HAL setup, Python interface, and machine logic — so I’m really hoping to just buy one thing that works reliably and doesn’t add another rabbit hole to the project.

What I’m looking for is a currently available, new industrial PC that:
  • Works reliably with LinuxCNC (using the preempt-rt kernel)
  • Is known to perform well with Mesa over Ethernet (7i94)
  • Doesn’t require deep tweaking to get good performance
  • Is ideally fanless or low-noise and compact (DIN mountable is a plus, but not required)
Budget isn’t my biggest concern — I don’t mind spending a bit more if it helps me avoid hours of frustration and trial-and-error.

If anyone has experience with a specific model (e.g., something from OnLogic, Beckhoff, or Fitlet2-type devices) that works well without surprises, I’d really appreciate a recommendation.

Thanks!

No it's still the same. The first clip is in CSS mode. The signal is gradually tapering up and down when moving in 10mm moves. You can hear the spindle nearly stopping as it's tapering up or down, only when it levels out again it goes to the required speed.

The second clip is out of CSS mode and manually pressing the Jog buttons. The signal has sharp edges as it's going straight to the required speed instead of tapering up or down .

I still can't figure out why this is happening. My VFD requires a 0-10v input. I'll hook up an oscilloscope to the speed input on the VFD and see what's happening.

You could import the 'hal' library and create hal pins like this (example here is a digital input pin 'log-trigger'):
 

after launching linuxcnc and the logger this should show up as a hal pin:

 

You can add the actions for these pin to the 'update' function (example triggers a log on pin 'log-trigger' changing from 0->1)

Hallo Hermann
Danke für die Nachricht, ja das ist richtig. Das wäre schön wenn wir uns kennenlernen würden. Wie schon sooft geschrieben ich bin erst in LinuxCNC eingestiegen hatte keine Ahnung aber jetzt geht es schon besser. Das nächste ist jetzt die Werkzeuglängenmessung an der Reihe. Muß mich erst erkundigen wie man den Taster Baut, habe gesehen das schon was in der Visialisierung vorgesehen ist.
Vorher war ich mit Mach3 unterwegs.
Gruß Hans

Leaving from TOOL page

Category: Gmoccapy

If I press any of these buttons, their commands are executed, but Gmoccapy switches to MANUAL_PAGE instead of staying on the TOOL_PAGE.
 

MANUAL_PAGE:
 

I think I could fix it. But I don't know if that was intentional.

It's a good idea to set this permanently in Geany:
stackoverflow.com/questions/5287849/how-...e-in-geany-on-ubuntu

I tested the code yesterday and found that it's a good idea to go back to MANUAL_MODE:
        if "G43" in self.active_gcodes:
            self.command.wait_complete()
            self.command.mode(linuxcnc.MODE_MDI)
            self.command.wait_complete()
            self.command.mdi("G43")
            self.command.wait_complete()
            self.command.mode(linuxcnc.MODE_MANUAL)
            self.command.wait_complete()

@rbobey1989
"EDIT"  My bad, I jumped the gun and didn't pay attention that it was PWM... I saw the EL25"" models and responded too quiickly, yeah I am supprised there isn't any either...

Yes, there are pulse train terminals in the code already and have been for years.  Look for EL2521 models.  I have these and they work.

If you bought some other terminal, then here is the code to the 2521 so you can have something to work from.

Also, those EL4032's are 12bit, the 4132's are 16 for when you are looking in the future.  The 4134 is also in the code for the last few years if you need to maximize terminal space...

Follow either of these two links and in the first post go down to PART 6 - LET’S SEE ETHERCAT WORK IN THE REAL WORLD .  There are detailed instructions on how to do the external Stop button and you should see how to do a start button also.
