I'm new to LinuxCNC and hobbyist machining.  For some reason, jogging isn't working on my 3 Axis setup. I feel like I'm just missing one critical configuration but can't figure it out.  I got homing to work from the Axis GUI, but jogging doesn't work. 

I've posted my INI files and HAL files.  I've only included X axis configurations for brevity.  Any tips ?

System Details
* Raspberry Pi 5 
* LinuxCNC 2.9.3

Hey kind folks,

I am working to configure a Raspberry pi 4B to run LinuxCNC for a two-axis machine I'm building.  I am using the HAL driver for Raspberrry PI GPIO pins (hal_pi_gpio).

I am proposing to use the following pins:

net Xdir => hal_pi_gpio.pin-15-out
net Xstep => hal_pi_gpio.pin-16-out
net Ydir => hal_pi_gpio.pin-18-out
net Ystep => hal_pi_gpio.pin-22-out

When I start LinuxCNC the HAL file appears to be loading properly.

But if I go to a terminal and say Halcmd show pins  - it appears to be showing my pins configured as INPUTS - not outputs?
(I'm assuming that's what the direction column in the show pins command means).

nc@raspberrypi:~/Desktop$ halcmd show pin
Component Pins:
Owner   Type  Dir         Value  Name
 
    28  bit   IN          FALSE  hal_pi_gpio.pin-15-out <== Xdir
    28  bit   IN          FALSE  hal_pi_gpio.pin-16-out <== Xstep
    28  bit   IN          FALSE  hal_pi_gpio.pin-18-out <== Ydir
    28  bit   IN          FALSE  hal_pi_gpio.pin-22-out <== Ystep

I'm pretty sure I did the math on the mask right although I could be wrong. To confirm, I just tried masking for one output and it still shows up as IN.

The documentation says I should add up the hex values for all pins that should be configured as an output which I think is what I've done.  

Anyone see what I'm missing?  Thanks!!!!

my full .hal file follows:

I have a good bit of experience with CNC... built 2 machines in the past... one Mach3 another GRBL.  Long time linux admin.  Have built lots of things with RPI, New to LinuxCNC.

I am refactoring a vertical mill that I converted to CNC and Mach 3 several years ago to use LinuxCNC.  In the past I used a UC ETH-300 which of course is not compatible with LinuxCNC.  So I bought a Mesa 7c81 and an 8gb Raspberry Pi 4.

I have everything connected, Installed LinuxCNC 2.9.2 using the RPI image, have enabled SPI and it appears that I am talking to the Mesa card.
I have a standard chinese BOB connected to port 1 and plan to use ports 2 and 7 for home/limit switches, probe, spindle etc.

Started with pncconf selected my card and the 5ABOB3 firmware, looked up my stepper drivers for time, space, hold etc... 

Cannot figure out the P1, P2, P7 Mesa Card config pages as far as pins goes... expecting to assign pin2 for step X etc...  according to the BOB documentation.
I have assigned the Axis StepGen's to P1 0:, 1:, and 2: just to be able to write the config out.
When I try to test/tune an axis I hear the relay trip on the BOB which is encouraging... and when I try to jog I see the numbers changing on the Hal Meter etc but I get nothing from my steppers... they do feel slightly warm so I believe there is current going to them... but no movement at all

if I try to launch LinuxCNC using the config pncconf created I see some errors come up
"Unexpected realtime delay on task0 with period 70000" and hm2/hm2_7c81.0 Watchdog was bit.

My plan is to get basic stuff working and then add complexity... 

Wondering if anyone has a config they would be willing to share?

Or advice on where to go next... been googling and searching my tail off and figure there is something basic I am missing and once I see it properly configured I will have a big DUH moment

Any help would be appreciated!

I am running LinuxCNC 2.10.x (developer version) on Raspberry Pi 400.
NativeCAM forked by BogdanTheGeek forum.linuxcnc.org/nativecam/48857-fernv...ernv?start=10#292321 works, but only standalone, not in tab. I am not able to run embedded
I think it should run in LinuxCNC 2.9.3 too.

Edit: now, with some raw workaround it appears in a LinuxCNC tab. But it is not fully working.
Edit2: corrected some bugs  in pref_edit.py, now it works better. I cannot update the file on GitHub.

Looking good on Pi4 with SPI connection to my Remora-style PRU.

The first post has been updated to include images for 2.9.3.
The Pi 5 is tested and working.
Any feedback about the Pi4 would be appreciated

updated for Linuxcnc 2.9.3 
Newer kernel 6.6.44
Better screen support for the Pi5
Now includes ethercat repos. Following the sticky in th eethercat section to install/

Pi4 Image  drive.google.com/file/d/1Fg2CPTezUyrRFrO...ytT/view?usp=sharing  
 

Apologies for the delay here. I was putting this off in preference to other Linuxcnc projects but its time has come

Pi4 Image drive.google.com/file/d/1Fg2CPTezUyrRFrO...ytT/view?usp=sharing 

Kernel 6.6.4 as per the raspberry pi's kernel git
Tested as working by Joco who bought a pi5 yesterday for the occasion!
Monitor support now fixed. He was using a 34" 3440 x 1440 monitor 

Ethercat apt repos now included
QTPYVCP repos a work in progress with the QTPYVCP team now VTK is in the Debian Repos.

There are no added programs, What was suggested was a bit out of left field as none of it was included in our AMD64 build.
Please read the downloads page on how to configure wifi, timezones and locales

 

Hi Rodw, Thanks for all the incredible work so far on EtherCAT. I'm diving into both LinuxCNC and EtherCAT right now and excited by the possibilities. 

I ran into the same issues as discussed.  I tried your script on the Rpi 5 and it seemed to connect to their servers but it only seems to have grabbed 733 bytes. I may try some of the other methods mentioned previously.

You need this linuxcnc.org/docs/stable/html/drivers/hal_gpio.html

Rod,

Also a newby here - trying to run LinuxCNC on a Raspberry pi4 and use the GPIO but getting an error that we don't have hal_pi_gpio module. Where do we find this? I've seen reference to this being part of Machinekit. Do we need to replace our existing LinuxCNC install with Machinekit or can we simply install the necessary hal_pi_gpio modules to get the GPIO running with our Pi4?

Now we need them to combine the newer 2350 with the W5500.

Hi all, 
I am way to learning about linuxcnc  in that i am trying to run lathe.ini with some modification for my drive sets, but its not working.its showing error like joint 1 following error. below i attached my setup files for your reference. Looking forward for solutions.(AC Servo drive(2No's)-MADLN05BE,motor-MHMF5AZL1U2M,and Raspberry pi-5). Linuxcnc build from source file(Run in place)

The Raspberry pi images do not include the Ethercat repositories but enabling some commented out code should enable it according to feedback from etherlabmaster
Try running a script something like this

Someone got the Vfdmod package for RaspberryPi? (arm)
