that is remarkable, because I flashed the latest image for pi5 for the second time and double checked my HAL and INI files. (the 'help' was indeed misplaced, and set this discussion on the wrong leg)

This is my loadrt command:

loadrt hal_gpio inputs=GPIO3,GPIO5,GPIO6,GPIO4 outputs=GPIO12,GPIO23,GPIO16,GPIO11,GPIO20,GPIO10,GPIO24,GPIO19,GPIO21,GPIO12,GPIO26,GPIO13

I will try to attach my ful config below.

this is from the report:

Debug file information:
Note: Using POSIX realtime
Failed to register output pin collection
hal_gpio: rtapi_app_main: Operation not permitted (-1)
./my-mill.hal:7: waitpid failed /usr/bin/rtapi_app hal_gpio
./my-mill.hal:7: /usr/bin/rtapi_app exited without becoming ready
./my-mill.hal:7: insmod for hal_gpio failed, returned -1
4465
Stopping realtime threads
Unloading hal components
Note: Using POSIX realtime

I ready that there is still tricky stuff related to get the pi5 going with hal_grpio, but I don't know exactly what it is.

kind regards,

Couldn't have done it without you:

github.com/jethornton/flexgui/commit/5fe...6058577c6ff811b15ac7

Thank you for that commit!

Behai,

Much appreciated, you've been a great help, that's great to know about RPi imager, I'm using the latest Mint which is based on Noble and using the same version of Rpi Imager and having no issues.

If you want to add a note in the thread below, regarding locales and your experience with PNCConf that would be great.
forum.linuxcnc.org/9-installing-linuxcnc...the-rpasberry-pi-4-5

Once again thanks.....oh if there's anything you feel that maybe missing in the thread I mentioned feel free to add to it. It'd be great if, as a community, we could try and assemble a lot of info in the one place.

Cheers

Hi. Sorry to pull up a decade old thread. But is there any solution to this? Using 2.9.3, and this problem happens a lot.

don't you need:

HOME_IGNORE_LIMITS = YES

since you have combined home/limit switches?

Hi,

As a LinuxCNC learner, I find this PNCConf video very informative and complete:



It is a few years old, but it did help me.

I've recently updated from 2.8 to 2.9.2  and I'm having issues with the homing of my dual y axis that uses a single limit switch (i'll be adding a second one for auto squaring in the future). Since migrating the Y axis will go to home and them give a switch triggered while in home state 10 error. I've tried adjusting a number of the homing options but none of them resolve the issue. So I'm wondering if there been any changes since 2.8 that would require this setup to be configured differently.

NOTE: I am using a 7i76E and I've attached my config and hal file for reference.   

Excellent! had to use every trick I know

This is typical of the move length and speed not being finished in the timeout requirement.
But that seems strange on the latch return.

What version of linuxcnc are you using and can you post a pic of the probe settings you are using (when it failed)

If you have two inputs on the Mesa card, connect a probe to each, then in the HAL file connect those two signals with an OR component. The output of the OR would then be connected to linuxcnc's probe input.

Actually I've just had another thought, what version of RPi imager are you using and what particular OS ?
I'm not a windows user and some people have had issues with RPi imager ?
Do you uncompress the downloaded file or just point RPi imager to the compressed file ?

Cheers

Hi Rob,

Thank you for your help and new information: I have missed the two links you posted on the previous reply.

I am using Ubuntu 24.04 Noble Wombat and Raspberry Pi Imager V1.8.5 to write image.

I downloaded the linuxcnc.org/iso/rpi-4-debian-bookworm-6...25-01-27-0404.img.xz and use it as is.

I did check the kernel with uname -a, and the output is Linux raspberrypi 6.12.11 #1 SMP PREEMPT_RT Mon Jan 27 02:47:25 AEDT 2025 aarch64 GNU/Linux.

AND I HAVE BEEN ABLE TO GET PNCCONF's Test/Tune Axis to test the X-axis motor: thank you again Rob.

-- For PNCCONF to work, we need to use menu-config to set Locale to en US.UTF8, after setting the locale, I had to restart the machine, otherwise the locale does not seem to take effect immediately.

To verify the machine locale, on a terminal window, run the locale.

Best regards,

...behai.


 

What does:

mesaflash --device ethernet --addr 192.168.1.121

report?

 

Thank you for all the feedback.
I think I will go fully EtherCAT for this machine to simplify the design and avoid multiple communication interfaces in a single machine.Mesa Ethernet or FlexiHAL controllers seem like a perfect fit for my second machine.

I can't seem to find a whole lot of info on this. As far as I've learned both probes need to be connected to the same input on a Mesa card, but of course that wouldn't work with my NC tool height probe. Is there a possibility to wire a touchplate to a different input? I cant find a good price for a NO height probe and I've already sunk a good deal of money into modifying our router, I'm worried my manager is going to start asking questions soon. I was thinking maybe invert one of the probes with a relay, but I'd rather not involve another component that may fail eventually.

I was also trying to use the height probe as a touch plate just to test it out, but the probing operation kept failing.
Running the latest build freshly installed with a Mesa 7I96 (PWM firmware)

Thanks in advance

Yes, I don't think its an issue but a /24 netmask
(255.255.255.0) makes more sense.

I do remember networks setup with WICD broke the static Ethernet
setup but network manager was OK
