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 belowand 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

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.

So, the reason that "make" is not doing anything is that the file in question is not mentioned in the makefile, as it is simply interpreted as and when needed.

(There is a complication that Python code is compiled to bytecode (.pyc) and sometimes that might be run instead.)

To be sure that your edited file is running, maybe put a "print("this is version 2.2.2") near the top of the file?

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.

Pots do not work with digital inputs, but encoders do, so given enough space the pots can be switched for encoders.
For rough analog, Mesa 7i77 has 4 analog inputs (in0-in3) when set in mode 2, you can try that and see if it is usable for you.
For outputs, 2.10 (or Master) has a nice feature where you can toggle inputs and outputs from the "show hal configuration" menu, so add the Mesa outputs by assigning some random names to pins, then use the above to toggle on and off outputs by clicking on SET or clear, as shown bellow:

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.

Sweet, so setting the following error higher allows it to run at higher speeds. What is the trade-off? Is it less accurate with a higher following error?

How do I know when to edit something in the .ini file vs the .hal file? it sounds like ferror is linked to a hal pin, but is configured in the .ini file..?

Then, regarding a completely different topic, I was wondering about the pros and cons of using the servo's built-in Homing mode. And if it makes sense to, how would I use HM to home, then switch to CSP for operation?

On the same topic of homing, how would I set that up? Is there a hal pin for homing that I would need to link to a homing sensor?

Hello, i have a project im working on (Not a CNC machine, but i believe a Mesa card is good capable hardware for this application) where im trying to determine the rate of acceleration of an externally driven spindle using an encoder. 

There doesn't seem to be any built in components for this that i can find.

The use case, is to feed the rate of acceleration into a PID loop to control the output of a stepper/servo that regulates the spindles speed.

Is there a relatively easy way to measure/determine rate of acceleration accurately?

Software rendering should not be a long-term solution.

Please post output of glxgears -info.

I love those good ol' X apps like glxgears; they are simple, yet suprisingly powerful.


Could you test on 2.9.4 or something by chance?

Perhaps this is a new regression; GPUs, especially NVIDIA, are often unsupported by newer versions of GNU/Linux (and FreeBSD too).

thx i thought the light would be on, and flashing while communicate. i just connected them to the ek1100 and no faults

Interesting work you present here! I might get a chance to start implementing a tool changer over christmas/new year.
