watch both videos, I think the following is motor tuning, connecting the home switch, and again I have a problem with the keyboard, the velocity changes when jogging, I need to find Tommylight's post on how to solve it. thanks:)

Hey Guys,some of you know so much about this Topic so I hope I can find someone in the mood to help me.Im trying to make a CNC 3-Axis on Raspberry PI5 and Beckhoff, the problem is that im completly new in this topic and try to learn as much as possible but i got already stuck in the beginning. EtherCAT works fine and i got the "Koppler" and Cards but if im trying to get them into LinuxCNC like some videos teach the Programm wont start anymore

If i start i get the message: Failed to register PDO entry: No such file or directory
LCEC: master 0 PDO enty registration failed

A friend and myself checked the code 10x, and it seems that the problem starts before. I cant get the EK1100 connected to TwinCat or CodeSYS, too. Whats kind of weird to me because as i said if I try it with the "ethercat slaves" command, it knows The Ek1100 and all Cards


Thanks for everybody who can help me with this and invests some of his time for me

You probably don't need to compile the gtk_little_probe.py file.
Python is an interpreted language, so often you just need to make the edits and run the code.

It is true, but not in LCNC.


If I modify this file:
/home/zdenek/linuxcnc/linuxcnc-zz912/src/emc/usr_intf/gmoccapy/gmoccapy.py

It returns:
The most important sentence is:
Copying python script gmoccapy

Id dont know why and where, but it works.   
gmoccapy.py is in /src/ folder and it works.

I placed the wrong file here, I meant:
/linuxcnc/lib/python/gladevcp/builtin-panels/gtk_verser_probe/gtk_verser_probe.py
You can try modify it, but noting happens.
MAKE doesnt see it.


 

The array data types are not implemented in linuxcnc-ethercat.
Not 100% sure about IgH Ethercat master.
 

i will make short video what is all about that problem later.

The following error can be large due to physical reasons, such as the axle sticking, tool breakage, etc.
With a good FERROR setting, the machine stops with a warning instead of destroying all sorts of things.
That's what you want. When the servos are working well, you should tighten the FERROR values ​​to get that protection.

Normally, values ​​are specified in the INI file.
With Ethercat it isn't so stream-lined yet, some values are set directly in the hal file like the pos-scale.
You can do it yourself, but it often introduces one more level of complexity when one just wants the machine to work.
In the ini file create a [ETHERCAT] section like below and use it in the hal file

Optional.

I am not the right person to elaborate on ethercat homing.
I use linuxcnc's homing variant with switches in the traditional way.
Many people have used ethercat homing, search the forum, or maybe someone chimes in.

There are 3-4 lines mentioning homing in the cia402 documentation github.com/dbraun1981/hal-cia402

 thank you very much for the answer, it will certainly help me later, now i have come to the conclusion that I could destroy the drivers by bringing 24v for enabling, it did not occur to me that the old controller gives 10v on that output, otherwise they are all 24vdc. and now here in the picture you can see these white wires, they are connected to enable on pin 7, however, the pin 6 from the driver just gives 10v and then I managed to short-circuit to pin 7 and the drivers are enabled, however, I still need to understand the estop chain so that the switch that supplies power to the drivers would stick, when I turn it on manually, the axes slide slightly to one side, maybe mm/min, I assume that the offset on the trimmer is not well adjusted, But, when all that I did it via the Mesa 7i77 card, i installed enable and brought the wires for the analog signal of the axis, when i start linuxcnc machine F2  axis move a little and stop(joint following error) (I will have to try to tune the motors first or maybe I should try to turn the analog wires ref and ref-?

Hello,
I try to integrate the security plc from Sick Flexi Soft via ethercat but I get the message that bitLen only allows 32 bits.
Are the restrictions limited to Linuxcnc-ethercat or do they also apply to the IGH ethercat-master.
   

It look basically OK but I do not have information on the plasma source pinout

G49, did you modify your tool setter macro? If not I would check that your var file and pb version are all correctly aligned and the parameters are storing in the var file.

I figured out how to setup homing mode in the ClearView software, and setup a home sensor, but I have no clue how to make it start homing when home is pressed in linuxcnc. I assume I need to do something with the joint.0.index-enable pin?

You can get acceleration by taking  the derivative of the encoder velocity pin with the HAL ddt component.
