The code (at least the code in your first post), works fine on 2.10.008.064.  I realize you are on some version of 2.9, just was easy for me to test on that. 

Can you state the specific version of 2.9 you are on (like above, as taken from the window title with QtPlasmaC open)?

Back when, there was a commit that temporarily broke feed reductions, but it was fixed. I honestly can’t remember if it was in 2.9 or master or both, but perhaps you have an older version that has the bug.

the best way to do this is to use the provided usertab, this way your edits remain with your config folder and do not get overwritten during updates (which a couple big ones are getting ready to drop). what you definitely do not want to do is edit the main probe basic because then you become the developer for any and all future updates which is not ideal for an end user.

to edit a user tab, open a terminal, type in:
editvcp

a dialog will pop up, in the dialog, find your machine config directory, typically it will be
/home/(your_pc_name)/linuxcnc/configs/(whatever_you_named_your_machine)/user_tabs/template_main/template_main.ui

in the file type drop down at the bottom of the dialog, make sure the type is set to VCP UI Files (*.ui)

this will show you the file :

template_main.ui

select it and click the open button.

Here you can add and edit it as you desire. when done, click save.

check your ini file and make sure that user tabs path is active under the display section:

[DISPLAY]
USER_TABS_PATH = user_tabs/

this activates the user tab and loads on probe basic start up.

enjoy!

If it was working and then changed I would expect that's more likely
to be a mechanical issue (loose coupling etc).

Two PCs were used in those machines.

Thank you

'comp' is listed twice. The first entry is correct:

 

The second is the wrong one.

Since that's a list of hal components, the link is correct
but the description is not.

OK, That's entertaining...

It should be possible to home by using a component that
measures the distance between index's and only arms
the actual index logic by simulating home switch detection
when the correct inter-index distance is measured.

Hello,

I tested the S-curve feature on the following system:
PC: HP with Intel i3 3rd Gen, 2x4GB RAM (latency < 20k)
OS: Debian 12
LinuxCNC: 2.10 pre-release
I created an XYZ mill configuration using StepConf and ran the same G-code with and without tpmod_scurve.
The results can be seen in the attached videos.
Observations:
Without the S-curve, the feed rate remains continuous.
With the S-curve enabled, the feed fluctuates significantly—at times dropping to 1/10 of the programmed feed rate.
It also noticeably increases the overall program execution time (2,5x slower with scurve in this situation).
I tried increasing VECTOR_BUFFER_SIZE to 100, but it didn’t help much. (Just for testing, I also set VECTOR_BUFFER_SIZE = 2, which made the behavior even worse.)
Maximum velocity and acceleration settings are visible in the video (they’re not particularly high, and are the same in both cases).
Question:
Do you think it's possible to achieve a continuous feed rate using the S-curve?

I was able to install it now, thank you!
Will update if it works as planed.

try:

variable int last_Tin = 0;

I acctually name it pos_latch.comp when creating the document.


I've created working functions before but those only used floats.
Follwing File installs no problem...:

Name the file pos_latch.comp, the comp thing makes it go through the preprocessor.

Hey Guys
I'm trying to write a function at the moment but it does'nt accept me using a bit.
Probably jsut missing something small.
I get following Error with following function;

CODE:
pos_latch.c:29:5: error: unknown type name ‘bit’
   29 | bit last_Tin;
        | ^~~
make: *** [/usr/share/linuxcnc/Makefile.modinc:117: pos_latch.o] Error 1


FUNCTION:
component pos_latch;
license "GPL";

pin in float Pin;
pin in bit Tin;
pin out float out;

variable bit last_Tin = FALSE;

function _;

;;

FUNCTION(_) {
    if (Tin && !last_Tin) {
        out = Pin;
    }
    last_Tin = Tin;
}

 

Twincat is a Windows program, a huge one with a learning curve so if you haven't use it before then it's not worthwhile now. It's anyway only an easier way to view data from the drive and it would be some detective work to see why yours doesn't go OP.
Google is your friend, or actually the search on this forum.
I found this forum.linuxcnc.org/ethercat/52997-ethercat-catio-module-help with what seems like a working config.
And you you should definitely do ajust to make sure the master's data about the client is up-to-date.
