Hey Guys, short question: Im playing around with Ethercat-Components at the moment.
I want to get rid of the LPT-Interface of my mill and drive the stepper with EL2024 Output-Clamps and some Buttons with EL1008.
Ive put all together and i see the devices when i run ethercat slaves
I use the generic-driver. I tried an old macbook and a virtual machine on a newer macbook with linuxcnc 2.6 and 2.7. I can list all clamps here too but when i start linuxcnc the complete system hangs and i need to reset the pc.
Do i need one of that intel-nic's or is the generic driver ok for that kind of application?
Is it possible to use the output-clamps for driving step and directions signals at all?
Regards, Jan

I would be very surprised if a VM could drive the ethernet port in real-time.
Also, the real-time kernel in a VM will not be real-time.
As it sounds like you have two Macbooks, I suggest converting one to "real" Linux (assuming it is Intel)

Ive used the vmware-macbook just for testing and configuring because the place around the machine is not enough to set it up at the machine-computer. BUT one macbook drives a vm and the other macbook runs linuxcnc nativly.
Both have the same problem. Both use the generic-driver and none of them hast a intel-networkcard.
So you think i will need one of the intel or realtek-cards to use that beckhoff-stuff?

Why don't you try to configure the ethercat HAL component from HAL console (executing halrun) before try it with linuxcnc?.
Create a .hal file with
You can load the file doing halrun -I halfile.hal and check some values with halscope or halmeter
Best regards.

Ive now tried that out. Ive used the macbook with native linuxcnc 2.6 and the millingcomputer with 2.7 and i get a kernelpanic on both devices. i can start axis for example with very basic hal-file or i can run halrun and after a while i get that kernalpanic. when its not crashing right after start i can open hal-overview and i can trigger the inputs and see that they are reacting. but after max. 2mins i get that kernel panic.
Following Crashlog i get:
Crashlog
When i put your code into a basic-halfile and start it i get a kernelpanic instantly.
At the end of the trace it says Code: Bad EIP value.

Dear all,
I have the same issue on D525MW motherboard with integrated network card and generic driver. I already try to put inside some other PCI card but I have still same issue as Dapeace - above.

Did you try one of the intel-cards and use the e100 or e1000-driver or did you only try another card with generic-driver? I think about getting a intel-card and try out again.

Hi,
I just try another card with generic driver.

Ok so there is a chance a intelcard could fix that.. i will try to get one on monday and report here if it works..
if someone has another solutions for that it would be very nice to know

Hi again,
today I once again try pci network card Tenda L8139D together with 8139too driver and system works without crashing now for more than 4 hours. I think that generic driver was not suitable for non of the cards.
Best regards.
