Thank you for your response,
I'm running linuxcnc on a raspberry PI 4, with a 7i92 + 7i73.
but I really don't understand what you mean, could you explain?

Thank's for the answer.
I have used linuxcnx → by_interface→parport →stepper →stepper_mm
I have modified the file  standard_pinout.hal with
# standard pinout config file for 3-axis steppers
# using a parport for I/O
#
# first load the parport driver
#loadrt hal_parport cfg="0x0378"
# Pour les GPIO
#loadrt hal_pi_gpio dir=67108751 exclude=0
loadrt hal_pi_gpio dir=35390224 exclude=31718639

# next connect the parport functions to threads
# read inputs first
#addf parport.0.read base-thread 1
# Je fais la même chose pour les GPIO
addf hal_pi_gpio.read base-thread

# write outputs last
#addf parport.0.write base-thread -1
addf hal_pi_gpio.write base-thread
#
# finally connect physical pins to the signals
#net Xstep => parport.0.pin-03-out
#net Xdir  => parport.0.pin-02-out
#net Ystep => parport.0.pin-05-out
#net Ydir  => parport.0.pin-04-out
#net Zstep => parport.0.pin-07-out
#net Zdir  => parport.0.pin-06-out

net Xstep           => hal_pi_gpio.pin-23-out
net Xdir            => hal_pi_gpio.pin-19-out
net Ystep           => hal_pi_gpio.pin-13-out
net Ydir            => hal_pi_gpio.pin-15-out
net Zstep           => hal_pi_gpio.pin-38-out
net Zdir            => hal_pi_gpio.pin-40-out

# create a signal for the estop loopback
# ça ne change pas
net estop-loop iocontrol.0.user-enable-out iocontrol.0.emc-enable-in

It seams to be easy to understand, except the first line
loadrt hal_pi_gpio dir=35390224 exclude=31718639

for this i used
forum.linuxcnc.org/18-computer/43353-rpi...tion?start=10#226664
to load rpi-gpio_1.0_arm64.deb

rpi--gpio -> the pins i used -> Get HAl -> loadrt hal_pi_gpio dir=35390224 exclude=31718639

That's all. Everything works as I need.
Thank's again.

For information, with a fresh install, I have always latency warnings. With halrun or linuxcnc
Unexpected realtime delay on task 0 with period 50000
I have tried to find something. It always appear at the very beginning of a task, never again...

Cordially

 

Hi Team, thanks to all who do the great work on this, especially Rodw and Cornholio in this instance, I'm a watcher but not regular contributor. Been using MACH3 for a many years on a 3 axis router at home and just completed a 15 month contract running vertical mills Doosan DNM400/650/700 with Fanuc controllers, so that was super helpful for me to up-skill on machining and cnc control operation. I have ordered a Pi5 and already have an ethernet MESA board so its time now for me to move on from MACH3. As soon as my Pi5 arrives I'll start doing some bench tests. Thanks, really stoked to see a Pi powerful enough and people seem confident in it.  What ever I learn I'll do my best to share in the group. Cheers
, Richard

QTVCP don't have debs for the pi in their repository so it was a dead end there.
Ethercat have pi debs in their repo and I built the linuxcnc ethercat driver for the pi and put it up on my repo. But neither have been tested.

Note we are not installing anything, just configuring apt so these companion prodcuct\s can be installed with sudo apt-get if the user wants to use them. Ethercat while open source has some pecuilar licensing requirements preventing linuxcnc from including it as we are a community, not a registered company..

(QTPYVCP is not available for the
pi).

Hey Rod, I saw this on the mail list.

Do you mean its not available on bookworm, or not available in general?

Yay! 2.9.1 is officially released. Grab your Bookworm  .IMG for the rpi from here
linuxcnc.org/iso/linuxcnc-2.9.1-bookworm-rpi4.img.xz

I will update the download URL in the first post once I gather the strength to tackle the forum editor!

Also note that Linuxcnc 2.9.1 is now in Debian Unstable which means in about 5 days, it will be in Debian 13 (Trixie)
Very cool!

Yes to bluepill, no to usb. You need to use a raspberry pi SPI

Work's fine for me.
Thank's.

Guys, sorry, I may not have updated the link in the first post.
I have edited the first post to include a direct link to the final IMG that will be the 2.9.1 release version.
Previously I had a folder with a few images that had been added over time. These have now been deleted.
NOte its now 2.9 not 2.10 becasue the gpiod driver was backported to 2.9
 

As webdeveloper, i have any cache disabled by default, so neither F5 (reload) nor shift-F5 (force reload) make any difference.
Did you take a look at the image, i attached?
[EDIT:] aaahhh now i understand .. the download icon flickers very briefly ... after "catching" it i was able to download the file from
drive.google.com/u/0/uc?id=10lxh9Icf07pw...X9dC&export=download
 

If you press 'F5' does the download icon appear in the top right corner?
If so then position your mouse over the icon, press 'F5' on the keyboard and left click your mouse.

i am clicking on the link - not copy pasting it ... maybe you have it in your cache ... google states clearly:

Download Permission: Viewers cannot download


btw: copy and pasting should work too, if download is possible at all

Yes that's the one.
See the edit in my post above.

 

the latest one from post forum.linuxcnc.org/9-installing-linuxcnc...y-pi-4b-400?start=10

I tried to download, but it says "File is in owner's trash"

Worked fine for me just now.

[edit]
Just left-click on the link in the post do not copy/paste it
