Beckhoff ethercat 64 with bit linuxcnc, How to install.

Hi Grotius!

this was quick yes, i hope this will be nice

GOOD NEWS! I managed to find the problem. At the installation of the preemt kernel i got the wrong header files choosen. Now with the correct headers and deinstalled unused kernel+header files this works so far! awsome...

Thank you for your quick response and generally for your nice feedback with those components. only because of that i am now switched to beckhoff for this upcoming project

Best regards
Conny

Hi Grotius,

my inputs on the EL1004 modules are working fine now At least on the second try. Now i know that you cant load the lcec component in the already existing postgui_call_list.hal! its a bit tricky because of postgui.hal in the description.


But one thing i have to ask:

Grotius wrote: I now use a EL2124 to guide 4 stepgen signals ( 4 motor pulse train's )

Does it mean you are using one EL2124 for 4 independent stepper drivers? if so, please tell me how can this be done if you need a 5v STP DIR and ENA signal for one driver.

Thank you!

@Nico,

Thank you very much for your tutorial. Sorry i was a bit late to thank you.

Respect for you

@Jim,

Does it mean you are using one EL2124 for 4 independent stepper drivers? if so, please tell me how can this be done if you need a 5v STP DIR and ENA signal for one driver.

2 pieces of this high speed (<1ms) output stuff is enough.



Switching times typ. TON: < 1 µs, typ. TOFF: < 1 µs

If a McLaren has this valve time, they will go faster....

Now i know that you cant load the lcec component in the already existing postgui_call_list.hal!
Is this for the Nico tutorial? Please provide more information about your item... This for other user's.

Hello Grotius!

so this means you dont use the ena signal on the drivers and ony stp+dir for one axis?

Yes, in both tutorials you have to create the halfile called postgui.hal. thats a bit confusing because when you use the (already) existig postgui_call_list.hal to shorten things up (i thaught in that moment), you wont succeed
What item do you mean?

Cheers,
Conny

@Conny,

That is correct. I don't use enable signals, do you know why?

Yes, in both tutorials you have to create the halfile called postgui.hal.

You need the postgui.hal file. It's a very good program flow for the linuxcnc software. Some developper's had to think about
this file at that time.

What item do you mean?
Yes, in both tutorials
In my tutorial there is no file like :
postgui_call_list.hal
