you mean buttons with indicator leds?
In designer:
select a HAL button or linuxcnc action button.
Look under properties for IndicatedPushButton
then set
indicator option: true (you should then see the led)
It will now reflect button state (if it is a checkable button)

If you want to control the led by a HAL pin then:
indicator_hal_pin_option property: true

If you want it controlled by linuxcnc status.
indicator_status_option property: true
set an 'is_SOMETHING_status property true

shape_option
on_color
off_color
circle_diameter (for round LEDS)
indicator size (for tri angle Leds)
width and height (for bar Leds)
right_edge_offset (moves LED to the left by pixels)
Top_edge_offset (moves LED down by pixels)

I think that's it in 2.9. In master you can flash the indicators too.

Pete's Latency histogram is for an i5

Interesting. PCW's histogram reports 3.0 gHz (which I expected)  and the N100 says nothing!
But as said the ping times means the servo thread is overrun before you get a response. My thoughts
would be to
1. install linux-headers for preempt RT
2. Install the R8168-dkms driver
3, Reboot 
4. Check ping times on different NIC's
5. Look at updating the CPU affinity for your chosen NIC. (refer other threads)

This may doc of mine may help:

I suspect that they use PREEMPT_DYNAMIC which is definitely not hard real time  PREEMPT_RT

COpy the linuxcnc folder and all of its contents to a new PC

Is there any tutorial how to add buttons-leds-selectors in qtdragon_hd ?

FreeCAD also has a surprisingly useful CAM feature. It is the only free one I have found that can do adaptive tool paths (HSM, Trochoidal, etc.)

I removed the o#number thing! This was what I hated the most! Also now subprograms are just searched by file name in same directory structure as $iemens, (current dir-> spf dir-> cus dir->…) 

 

Those two things are near the top of my LCNC wishlist.

Can't wait to see future progress.

The kernel errors would be interesting to see, some spec on the old vs new system could help as well, information, we need information.

Another thing would be to try a live boot from the same version that is running on the hard disk.

Where did you read this ?

"I read somewhere that xxxx" often comes up but rarely is there a source.

It may not be not needed by Ubuntu, but its certainly needed by LinuxCNC...

If the output5 does not start the spindle (but is controlled by the expected m codes),
that suggests that output5 is not wired correctly to the drive. The LED indicates that output
5 is on. On meaning a connection is made between OUT5A and OUT5B.

Do you have a drive manual?

"maxvel is too large for current step timing on stepgen 04"

Means that the current steptime and stepspace settings and current step scale
will not allow the maximum velocity you have specified. (its just a warning and
will not effect operation but you will not be able to reach the velocity specified
in your .ini file)

 

I read somewhere that rt PREEMPT_RT kernel build was no longer needed in Ubuntu 23.10/24.04. Is this true? If so how do you access the real time features?

So, I went to boot up one of my computers today and it would not boot. The motherboard was dead.
In an effort to get the machine going again, it is just for testing and simulation, I removed the hard drive from one computer and installed it in another. Now it will boot and I can log in but the system freezes after a couple minutes of operation. If I have a network cable connected I get kernel errors.
Any Idea on why I cannot just move the hard drive install. This pc has ran an linuxcnc install previously, granted it was a different release 2.7 vs 2.8.

Just looking for ideas. I was needing to test some new gcode tonight for first thing in the morning. It is a custom 5 axis machine that I need to simulate using this config. Lots of customization.

Any Ideas would be helpful.

Thanks

Output 5 is wired in hal to spindle-enable, probably should be tied to spindle-on.
And please do not use DOC or any office documents to upload stuff here, they are very prone to macro viruses.
Upload normal hal and ini files.
Thank you.
