I have installed LinuxCNC ver 2.9.7 including linuxcnc-uspace. LinuxCNC seems to be running fine.

I'm trying to learn HAL and coded "loadrt motion" in my playground HAL file.

When I open my playground config in LinuxCNC, I keep getting the error: "motion: dlopen: /usr/lib/linuxcnc/modules/motion.so: cannot open shared object file: No such file or directory"

When I run "dpkg -l | grep linuxcnc", I see: "ii  linuxcnc-uspace  1:2.9.7  amd64 motion controller for CNC machines and robots"

When I view the "/usr/lib/linuxcnc/modules" directory there is a "motmod.so" file but no "motion.so" file.

It is my understanding that motmod.so was part of LinuxCNC v2.8 and older and motion.so is part of LinuxCNC v2.9 and up.

I am a new to and just learning LinuxCNC as I prepare for a manual lathe CNC conversion.

Am I doing something wrong? Is there an issue with my LinuxCNC install?

Thanks!

I think it should be pretty easy. I did raise an issue about Trixie support and they actioned it.
Download this script,
forum.linuxcnc.org/ethercat/53785-instal...thercat-repositories
change the Debian_12 to Debian_13 and run it in the main user script that installs our custom stuff.

We don't install anything, just set up the repository apt update will tell you if there is any error. You will see warnings about the key will expire in 12 months which is not our problem



 

If you are already here, you should really watch this, it is by far the most comprehensive video for complicated and parametric stuff.

Do you have the drive manual?

Is this a 5V push-pull output?

 

Dank Hilfe aus diesem Forum bin ich jetzt ein Stückchen weiter.
Den I/O-Bereich meine 7i76eu (TB1) habe ich an einen 12V Ausgang meines ATX-Netzteiles angeschlossen. Ebenso den P4 (mit 5V).
Die Näherungssensoren für „Home“ liefern entsprechend ein verwertbares „True“ auf der Karte.
Ein SSR, dass das 48V-Netzteil für die Schrittmotoren einschaltet funktioniert auch.
(Netter Nebeneffekt ist, das ich mir das Enabled der Motoren sparen kann)
Jetzt stehe ich vor der Frage, wie ich das Alarmsignal der geplanten Closed-Loop-Schrittmotoren (die ja nur 5V liefern) in die Software bringe.
Die „Input’s“ der Karte scheinen nur auf die 12V zu reagieren.

=11.0ptMuss ich da einen Transistor zwischenschalten, der mir aus den 5V ein 12V Signal macht?
=11.0ptWenn ja, was sollte ich da am besten nehmen (Transistor/Schaltung)=11.0ptOder gibt es noch eine andere Möglichkeit?

Thanks Peter I will try all of the above.

Hiya,

I'm new and am going through the documentation for the first time. I have noticed some typos so figured I'll fix them while I'm here.

As per  linuxcnc.org/docs/stable/html/code/contr...rview_of_the_process , this is my attempt to communicate with the project developers and let you all know what I am hacking on, explain what I am doing and why.

I've cloned the repo and will submit a pull request with some changes as soon as I figure out how to do that.

I'll also send a message to the mailing list. Please let me know if anyone has any objections or concerns.

Regards,
John

You have to compare with the data sheet of the recom www.tme.eu/Document/cd1b5f2ae4e38e422d024220d341ab42/RS3KZ.pdf
It looks like Ctrl is reversed? Apply voltage to switch off? Or am I wrong. One want the module to be off and actively switch on.
 

i only found URB2424S-3WR3 Hi-Link on aliexpress. specs in attachmentDoes it fit?

 

I have found a solution to the problem often seen when trying to compile Kinematics (or occasionally other) modules  from C-code with halcompile.

Solution:

Make sure that the .c file contains the following code and the problem should be solved.

This requires the file to supply an app_main and exit:

Explanation

Halcompile creates a Makefile to compile the component. This includes Makefile.modinc

Makefile.modinc contains this code:
Which is what creates the modulename.ver file that the complaint is about. Without #include "rtapi_app.h" the .rtapi_export section doesn't exist, so the .ver file is invalid.

Adding the header is enough to complile the module, but it will then fail to load without an rtapi_app_main()

It wouldn't have anything to do with jaw lift when tightening the vice ?
Does the fixture support the stock fully along the side that is contact or have you allowed for a "hollow" in the middle of the design of the part and fixture allows for this.

I'll need your advice regarding setting up Ethercat repos Rod, and whether a 6.12.34 kernel is supported. As I kept to the RPi rt kernel from their repo. And one kernel supports both the 4 and 5.

I only found this recom dc-dc converter and bought it from tme.eu
www.tme.eu/en/details/rs3k-2424sz_h3/dc-dc-converters/recom/
I see that Mouser, Digikey, Farnell and those big ones have the item.
Can't find it on cheap places ebay, alix etc.

I'm not too sure if this may help
github.com/MichaIng/DietPi/issues/6577

The power saving feature shouldn't be kicking whilst there is traffic, but stranger things do happen. And I know the RPi is on a later kernel.
Actually that reminds me I'll have to talk to Rod about Ethercat repos for the new image.
