i tryed RMII with the tangnano9k, bitfile generation works, but get no connection
better go with esp32:

github.com/multigcs/LinuxCNC-RIO/tree/main/UDP2SPI-Bridge

i prefer the WT32-ETH01, cheap and available

I knew there was another HAL component that might be relevant, I don't know how I missed it:

Andy,

I need some clarity on a few points for sendkeys.

At this point I have an Arduino board that can trigger events in halshow, So when I activate an Arduino connected push button, the jog-x-pos and the halui.axis.x.plus changes from yellow to red. I expect the actual X-axis to jog when I press that button, however other than the yellow to red indication nothing happens. (the system is NOT in Estop, and the machine is enabled on the manual control tab. If I mouse click on the "+" button, the x axis does jog.

Do I need to enable/invoke SENDKEYS, to actually get the yellow to red indication of jog-x-pos to do something?

Assuming that I do need to enable SENDKEYS, I need a little help with a few points in the SENDKEYS documentation.
 Instructions say "Create a new entry in .B/etc/udev/rules.d/99-input.rules"

I'm not sure where ".B" is?

I did find       /etc/udev/rules.d/70-persistent-cd.rules
So neglecting the missing ".B"  I assumed this is the file I'm supposed to update?
However when I add "sudo echo KERNEL=="uinput", GROUP="uinput", MODE:="0660" | sudo tee /etc/udev/rules.d/70-persistent-cd.rules" to that file I get the attached error message. So lots of possible mistakes here: wrong location, wrong file, adding the uinput group did not work even though it seemed to (see last attachment) the discrepancy between 99-input.rules ,77-persistant-cd.rules , 88-input.rules?

Please advise.
 

 
 

Hi Arciera,

Ok, I will not worry about it.

I tried a free gcode file, a griffins logo. File about 14000 lines.
www.cnccookbook.com/g-code-examples-file...for_Milling_Machines

In the file no G64 P.. Q.. was given. Raw output :
 

Then i added G64 P0.1 Q0.1
The output : 


Then without the velocity display :
 

The purple are all clothoids. Cyan is spline, White is line.

File specs :
items G64 P.. Q.. before:14151 after:28292 diff:-14141
So the gcode file is increased by 14141 segments.

Maybe test some more files?

At the moment a UDP2SPI bridge (esp32) is still the best solution.
 

This one?
WT32-ETH01 ESP32 Ethernet Development Board 

Don't worry about it, it's really not important.

@meister

Late on and I got it to work. However and as you've pointed out, the comm needs fine tuning! Can I bother you once more and ask for a detailed hardware desc for the ESP32 you've mentioned? Is there a UDP module in particular you'd like us to use and dev around? I'm also happy to get a RMII breakerboard as a second option. Both would be ideal though. All-in-all it's working well. Congrats!!

Visual of the w5500 output:

Yes, i saw some posts but they did not share any clear results.

Thank you.

Hi Arciera,

I can write gcode file output tomorrow, but clothoids & splines must then be converted to a G1 linestrip.
Then the overall output is G1,G2 or G3.
Is this ok for you?

this says it is conflicting

following the steps indicated, it says that I must uninstall any traces of Linux, but I receive the following message.

To install on Debian 12 with linuxcnc-uspace already installed use : sudo apt purge linuxcnc*  and wait for apt to completely remove every trace of LCNC.
but it happens this way

1 linux image
2 linux headers
3 linuxcnc
4 rtai modules
OR
3 rtai modules
4 linuxcnc

Gdebi will tell you if there is something that needs to be installed.

Cant do this anymore bye all wrote:

Start with the kernel packages, then I think there are some modules then finally the Linuxcnc packages. Best thing is to read completely read through both threads linked in the previous threads.

Your avatar is scary, but you look like a good person!

I'm able to understand things

Do a new full install and start over.
Never use root or SU to install stuff as everything will be installed in the root folder and nothing will work as a normal user, always use sudo.
LinuxCNC will refuse to run as root due to having full hardware control and stopping misuse.



Before seeing your post, that's what I did, so I was right to do a new installation
Thank you, now I need to know something, are there 4 files, should you install all 4 or just one?

linux-headers-5.4.279-rtai-amd64_5.4.279-rtai-amd64-1_amd64.deb
Arquivolinux-image-5.4.279-rtai-amd64_5.4.279-rtai-amd64-1_amd64.deb
Arquivolinuxcnc_2.9.2_amd64.deb
Arquivortai-modules-5.4.279_5.3.3-linuxcnc-delta_amd64.deb
   
 

NOT my stuff!!!

Several videos of building a strange 5 axis machine with hand tools, he does a great job of explaining every step in detail:

Thank you very much, I will test it as soon as possible, get back to you if everything goes well
