Hm, as usual I'm concerned about unwanted path distortion:

 

I presume these splines were added by the algorithm, if so it seems like a lot of distortion for 'G64 P0.1 Q0.1'?

Hello, I just heard of this software,
Seen it in Youtube video
"Building The 5-Axis CNC Machine in a Small Room: A DIY Journey. (Part12)"

Does the software reduce the RPi's cpu load?
or,
Does the RPi still run X and OpebGL and Axis gui?
(I _think _ nhose are the alternatives )

Thx

sudo apt purge linuxcnc-uspace linuxcnc-uspace-dev

Thank you Mark!

Here is a picture of the back side of the panel, 7i73 reading switches, 2 potentiometers and mpg encoder.
It also drives 30 LEDs under switches (multiplexed). The multiplexing is currently done in hal but I will try to write a component for it.

 

And this is a custom power detection board. Basically just 12 AC optocouplers and a relay output to detect a open breaker or motor overloads.

 

Also do you insert pictures in posts as attachments or someway different. On some pictures even if I compress them, forum still complains about large file size.

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?

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.
