I had a look at the ethercat DKMS package (extracted the package in a temporary directory, no need to do an install), and what I saw is that the source of the modules have ending with 5.14 & 6.1 before the .c .h extension (I'm guessing these are the supported kernels). I'd get confirmation that the commit for 6.11 will work for 6.12.

Hello everyone,

I started to work with linuxcnc only a few weeks ago, when I decided to upgrade my 3d printer with A and B axis.
Because my pi4 was starting to jitter I acquired a pi5. As one does..

I etched the image 2.94 for pi5 to an SD card. Running this image, GPIO is not working.

halcmd loadrt hal_gpio help
Note: Using POSIX realtime
Invalid parameter `help'
<commandline>:0: waitpid failed /usr/bin/rtapi_app hal_gpio
<commandline>:0: /usr/bin/rtapi_app exited without becoming ready
<commandline>:0: insmod for hal_gpio failed, returned -1

I dont have the knowledge to troubleshoot this. Unfortunately. Maybe somebody here know how to solve this.

kind regards,
JAiro
 

halcmd loadrt hal_gpio help
Invalid parameter `help' <<<<< this is the error from the above, Linux is pretty verbose in telling you what is wrong.

But you really need to read the man page
linuxcnc.org/docs/devel/html/drivers/hal_gpio.html

 

Thanks PCW.

Yes, I had the Ohmic sensing into the B encoder input on TB2.

Once this was unpluged, Encoder velocity stayed at 0. or flucuated to -3750.

Grounded everything i could and moved plasma source 30cm further away.

And hey presto.





 

From memory, GEANY can convert WORPAD, MS-DOS text to text format, and has a function for this in the program.

HMMM. Let's see, how much I.O. do I need? Might just try that in the future.

Can you share the files? Using Gcode how LCNC know where are the XYZ coordinates of a tool?

hal_gpio uses a newer method that is meant to support other ARM hardware, not just the PI. Code changes at the kernel never stops!

yes exactly, a sequence of gcode linked to the buttons on the gui
with cycle stop and error message in case something goes wrong

Hello All,

New 7i97T last year and only just got time to work in it.  I'm new to linuxcnc and mesa boards and would appreciate advice on this setup.
CR7 and CR8 switch off so FPGA initialisation is fine
Ping 192.168.1.121 works fine and green user LEDs count ethernet packets correctly
Response of Mesaflash version 3.4.9
mesaflash --device 7I97T --addr 192.168.1.121 --readhm
=  'No 7i97t board found'
 
Response of MesaCT version 2.1.7
= 'Device found at 192.168.1.121 is not a Mesa Board'

I am thinking the board should be more revealing than this and wanted to check before proceeding with linuxcnc setup.
Thanks tom

 

The images provided are not generic Debian images, as generic Debian didn't support overlays.
The images we build are custom images based on Debian repo but with kernel sources from the RPi-Linux github.

The output I gave was showing that the hal_gpio driver does indeed work, the first line is loading the driver with the GPIO config as per the man page for the driver. Yes it was the current image, with the 6.12 series kernel & Linuxcnc 2.9.4.
