Thank you for this. That did the trick, but I have a couple of questions.
How am I running a raspberry pi all of a sudden?
And
Is it possible to install a nvidia graphics card and still use Linuxcnc?
Thanks again

Thanks. When I use the naming in the linked config instead of the naming from docu it works!
I can see dir and step signals now on the correct pins.
One last problem before I can test with the machine. I use an enable signal for the stepper driver. I see it on the pin, but inverted. Is there a possibility to invert output pins at raspberry pi 5 or should I better do it in hardware?

First hint is here:
The GPIO line PIN3 can not be found.

PIN3 isn't a name of a pin, pins are named as per man page.

Thanks for your fast reply.
That's the output of "gpioinfo", looks ok for me:

Have you run the "gpioinfo" command? That will list the available pins. If it doesn't work that may mean that you don't have gpiod installed.

Is your user account a member of the "dialout" group?

Not able to get outputs on GPIO of Raspberry5

Category: Installing LinuxCNC

Hi,
I'm a bit desperate. I want to replace my very old pc based linuxcnc with the actual version running on a raspberry pi 5.
I've been trying to get signals to the pin header for a day now.
First of all: Is there a tutorial for raspberry configuration? I found nothing except the general docu and then went from one error message to another.
What I did is:
1. Started Stepconf wizard
2. Replaced parallel port Pins with hal_gpioxxx, see attached hal file

File Attachment:

File Name: AndyCNC.hal
File Size:3 KB

When I start this Setup following error occurs:  

File Attachment:

File Name: linuxcnc_report.txt
File Size:6 KB


This was my try to set the PINs:
halcmd: loadrt hal_gpio inputs=PIN3,PIN5,PIN7 outputs=PIN5,PIN6,PIN9,PIN10,PIN11,PIN17,PIN22,PIN27
Note: Using POSIX realtime
The GPIO line PIN3 can not be found
hal_gpio: rtapi_app_main: Operation not permitted (-1)
<stdin>:12: waitpid failed /usr/bin/rtapi_app hal_gpio
<stdin>:12: /usr/bin/rtapi_app exited without becoming ready
<stdin>:12: insmod for hal_gpio failed, returned -1
halcmd: Note: Using POSIX realtime

Would be nice if onyone could show my where I'm wrong.

Andy

Thanks, Andy, you steered me in the right direction.

GPIO13 would not work at all, continuing to research that.

GPIO25, once pullup=GPIO25 was added, works.

I only have 1 limit switch setup, so I'm fully functional with the official image, Byte2Bot board, and my old Probotix motor driver setup.  Attached are the .hal and .ini files that worked, and my config.txt

Hi Andy... I am muddling my way through this and have things working really well, except inputs. Gpio reads gpio13 fine in python, hal_gpio always shows high in hal scope, meter etc. Any ideas? Is there a way to set gpio characteristics with hal?
 

You can try setting the various modifiers for GPIO13 and see if that helps.
opendrain
opensource
biasdisable
pulldown
pullup
As described in linuxcnc.org/docs/devel/html/drivers/hal_gpio.html#_usage

I am not clear if you are saying that it is always set and the input can not be changed, even if pulled low?

Have you checked with gpioinfo that nothing is claiming the pin?

Important Info Regarding Rpi4/5 Images.

Category: Computers and Hardware

For the Linuxcnc Raspberry Pi images just don't do dist-upgrade, it will break things, this has been proven.

You get get away without doing any kind of upgrade.

If you are worried about security, updates are only a small part of the picture. The first step should always be physical security, which should be the number one priority with a computer running a cnc machine.I'd take data loss over damage to a cnc machine any day of the week, you can't back up a cnc machine.

RPi + Mesa + high CPU load gives stepper stuttering was created by pgf

RPi + Mesa + high CPU load gives stepper stuttering

Category: Computers and Hardware

I think I've probably been having this problem since I first started using a raspberry pi to drive my mill.  I noticed some CPU-related "hiccups" from the motors early on, and got rid of some background processes that were causing them, and didn't think anything more about it.  But today I noticed some new stutters/hiccups from the motors, and while trying to reproduce, started dragging the Axis window around on the screen.

Well, hoo boy...  the mill sure didn't like that!  Obviously, system load is affecting LinuxCNC in ways that it shouldn't.

So.  I must be doing something wrong, because I assume other people run X11 on their RPi HDMI monitor, and don't have this symptom?

I'm running the RPi 2.9.4 .iso (kernel was built 1/27/2025).

It's driving a Mesa 7i96.  I don't use wireless.  One ethernet is the built-in Pi interface, the other is a reliable USB/Ethernet dongle.  It doesn't matter which drives the Mesa, the symptom remains.

My cmdline.txt looks like this:
console=serial0,115200 console=tty1 root=PARTUUID=c8fda93c-02 rootfstype=ext4 fsck.repair=yes loglevel=5 net.ifnames=0 processor.max_cstate=1 isolcpus=3 firmware_class.path=/lib/firmware/updates/brcm rootwait skew_tick=1 kthread_cpus=0-2 irqaffinity=0-2 rcu_nocb_poll rcu_nocbs=3 nohz=on nohz_full=3

Most of that cmdline came from other posts on the forum.

I tried adjusting the IRQ affinity for the Mesa ethernet, to move those interrupts onto core 3 along with the rest of the real-time stuff, but that didn't help.

I'm sure I can find a PC that will work (I did some tests today on an older Thinkpad, with surprisingly good results), but I use the RPi gpio pins to help work around a LinuxCNC shortcoming, and I'd rather not lose that.  I will if I have to, though.

Any ideas, suggestions for things to try?

Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

Hello scotta,

thank you for your quick reply. Yes, that is exactly what I thought myself.

The EC500 is powered by an external power supply. From the 6 pin header, GND, SCK and SDO have been connected to one of the probes.

I don´t have any kind of schematic on hands for the EC500. So I am not shure, why the header pin is labeled SDO. I would expect SDIO for a sufficient SWD connector. Is your header labeled with a SDO too?

My EC500 is labeled with IMXR_EC500 2023-05-18

Up to now, there has not been a single successful flash. From within MCUExpresso, I am at least able to build your application.

If this is not going to be successful: do you think, your actual project with W5500 and raspberry pi pico is as powerful as the 1052 solution and could be a viable alternative?

Thank you very much. I will try to give more details tomorrow.

Cheers Julius


 

I'll need to check the labelling on my boards. With MCUExpressoIDE does it report an error when trying to connect. It may give some clues.
Remora supports quite a number of 3D printer boards. The EC300/500 being 24V IO is more suited when using industrial hardware.
