Category: HAL

Hello There
new problem, new topic:

Newbie here, i am trying to set up my milling machine, but i keep getting errors from hal_gpio:

Note: Using POSIX realtime
The GPIO line GPIO4 can not be found
hal_gpio: rtapi_app_main: Operation not permitted (-1)

if I am trying to do it in the terminal it still doesnt work:

halcmd: loadrt hal_gpio outputs=GPIO13,GPIO19
Note: Using POSIX realtime
The GPIO line GPIO13 can not be found
hal_gpio: rtapi_app_main: Operation not permitted (-1)
<stdin>:6: waitpid failed /usr/bin/rtapi_app hal_gpio
<stdin>:6: /usr/bin/rtapi_app exited without becoming ready
<stdin>:6: insmod for hal_gpio failed, returned -1

Tried fixes:
adduser and gpasswd
linuxcnc.org/docs/devel/html/dr ... _gpio.html troubleshooting
archlinuxarm.org/forum/viewtopi ... 65&t=16838 (i know its arch, not debian..)
viewtopic.php?t=8999 (poor mans fix)

i really need some help quickly, have to present it to my team in 12 hours. Thanks for everything in advance!

Setup:
Raspi5
LinuxCNC 2.9.1 (debian)
Milling machine BADOG Cubique
Driver: Badog CNC MikroNC

I did something, to display the correct time choosing Kyiv (Ukraine) in local.... something (and want to use other languages to type and search on the internet)
May be that was the cause?

I can't finish the PncConf...
After setting the steps/mm pressing the forward button pops up this massage. Is it possible to solve it?

Thanks!
I will try it at home.

If there is any issue with the "because device is strictly unmanaged" while activating the connection, this helped me

My Cable Robot CNC Foam Cutter is running!

Category: Show Your Stuff

Hey kind folks,

I thought I’d share a quick video showing the status of our Linux CNC foam-cutter project. I’m brand new to LinuxCNC and basically just took this on as a fun project to learn a bit. 

photos.app.goo.gl/ksw5mnEoJEibSiqs5

The drive drums are custom designed 3D printed hypocycloidal drives running a pair of cables to a hot wire knife.  The 3D printed drives are a bit janky but actually work surprisingly well.  Not sure how durable they’d be in the long term. 

While this test-bed is quite small, the objective is to be able to mount the drum modules on a wall some 12 feet apart and in doing so be able to cut shapes out of large foam sheets. The objective is to be able to build an ultra-low cost CNC foam cutter for less than $200.  I could then manually stack the cut sheets together like a loaf of bread and build very large 3D printed objects ala a huge FDM (albiet with 2” thick layers).

Given the lower speed we’re running the unit on a Raspberry Pi.  I’m sure the latency is a mess but it appears to be tracking.  The forward and inverse kinematics functions were the majority of the challenge - I made life much more difficult by running the cables tangential to the drums instead of through a fixed ferrule but I was eventually able to solve the kinematics.  The inverse kinematics were just trig but the forward kinematics required numerical methods (Newton-Raphson) which I only sort of understand but seem to work.

More to come to make this more useful. If there is any interest I’ll likely open-source the whole thing when it’s a bit more stable and refined.

Thanks to all of you who helped on here through my rough patches.

Can you tell me how can I rotate the touch part of the screen too?

Try this, otherwise it is a mess to sift through endless posts on several forums to get the right answer, been there and done that, twice.

THANK YOU VERRY MUCH!!!!

It looks great!
Finally i can rotate the screen! Also there is sound on the mini HDMI monitor .
Can you tell me how can I rotate the touch part of the screen too?

LitexCNC: firmware and driver for 5A-75B and 5A-75E

Category: Driver Boards

Hi everybody, 

many thanks for the great work you are puting into this Project. 

I have some issues, maybe somebody can guide me into debugging it. 

I bought a 5A-75B V8.2 and managed to flash it without issues using a Raspberry Pi 4. The JSON used was the example from the documentation , 5a-75b_v8.0_i12o14p6s6e6 . I have not made any changes to it yet, as I just wanted to test the whole process first and see if I get into issues down the road. Now, I don't know if using the json for version 8.0 is causing the issues that I have. 

The board is pingable over network, and can also be loaded into halrun:

Thanks again for your help.

NativeCam on LinuxCNC 2.9.3

Category: NativeCAM

Now NativeCAM is running with Python3 and Gtk "without" problems, at least as standalone.
There are some problems and Gtk deprecations to fix. but it works.
On my Raspberry Pi machine it runs enbedded in LinuxCNC too.
I think all of you could run it as embedded configuring paths etc...

2.93 seems to work great on my pi5. No network manager is a bit hard for my brain but we'll get there.

Blazing fast compared to the img I had loaded up earlier, lcnc boots up faster than I thought was possible

​​​​​​I wish PiClone was already on there because no Ethernet in the garage and the pi is a pain to remove from the cnc haha

I have seen those problems. When I'll have some spare time, I'll try to fix them.

Since at this moment I have no much time I attach a text I have found recently.
Maybe the author is Fernand.
You have a standalone version of NativeCAM working, so I think you have only to made changes to embed it in LinuxCNC.
And I suppose you can run ncam from any place in the terminal simply by typing ncam.

You could follow that guide in the first 4 points to try to have NativeCAM in a LinuxCNC tab.
Remember to verify your paths.
In my case they were different respect those writtten in the guide and I had to adjust them.
One of the differences is the path:
/usr/share/pyshared/gladevcp
on my Raspberry is:
/usr/lib/python3/dists-packages/gladevcp

You can firstly verify the situation listing the directories.
If you write down the changes you make (I haven't...
File Attachment:
) the guide could be written by you.

NativeCam on LinuxCNC 2.9.3

Category: NativeCAM

Hello,
can't you use as a LinuxCNC tab? It should work. (On my Raspberry it works)
The original script does not work completly.
There are some setting to do by hand. Actually I have set all by writing in the terminal.

There is the last "version"  attached.
The input field after the "Change to GCode" now pop-up. But there are still many hidden errors and depracations to fix.

I have not understood the mean of that function.
I see (and I see in the code too) that changes the input mode from number to text and back.
When shows-up the calculator you can input only numbers, when pop-up the input field you can input letters and numbers.

Regards
Giovanni

NativeCam on LinuxCNC 2.9.3

Category: NativeCAM

Hello,
I am happy to ear that my little fixes are useful to someone.
To me is useful your feedback and I think it would be useful to test NativeCAM on various computers.
I have a question for you real users: if you input numbers in the fields by doing calculations, is the result correct or a huge number is given?

I ask you that because I am testing NativeCAM on two machines: standalone on a iMac and embedded in LinuxCNC on a Raspberry Pi (the real LinuxCNC machine).
Calculations on the Mac are correct, but on Raspberry Pi are wrong.

I am not a Python or a NativeCAM expert (I am learning Python while trying to fix Native CAM), but I hope to be able to fix some problem.

Regards
Giovanni
