Junction error 1: This error only occurs when I watch YouTube videos. With only LinuxCNC running and CPU stress test (and rustdesk remote desktop), the job runs without errors until the end.
this is the end of my machine?

How are you controlling 4 axes with a 3-axis driver?

OK then, feel free to poke around, you are always welcomed.
I was thinking you have some non standard stuff or end result, hence my jumping in.
Thank you.

Looks perfectly fine, so do some tests with Mesa card attached and again do copy some stuff around, play video, etc, see if it drops the link.
If not, move on to making chips!

Tommy, thanks for taking the interest.

My aim was to simply improve my knowledge of some of the more exotic GCode.

As stated, my assumption on what G10 can do is incorrect.

My skill base has, however, improved because I can now use G10 for its intended use of setting up Offsets for multiple jobs.

Thanks , this is result with nouveau(and rustdesk for remote desktop):
 

It would be much easier to help you if you told us what are you trying to achieve or what the end result should be or ...

Much better.

Most probably, but if it is working with RT kernel, do give it a try
latency-histogram --nobase --sbinsize 1000 --show
while playing youtube, skipping through it and maximizing/minimizing the video.

installed [code]r8168:

no packet loss this time with r8168!! thanks !

i have system with the nvidia proprietary driver i need to go back to nouveau?

Thanks for the response.

Once my machine is set-up correctly, I successfully use multiple Offsets to do jobs on the table.

I started this investigation of G10 'assuming' that it was used to set-up the machine without having to physically move it to the Home position.

So far, that assumption has been demonstrated to be false.

What does one do if the machine cannot be physically moved to its Home position ?
For example, a large job mounted prior to machine start-up, or a vice.

Note: I simulate physical table movement at start-up by operating the controls with steppers Off to the position measured by ruler.

NVIDIA proprietary drivers do not work with RT kernel and neither do new AMD drivers.
Most of the time NVIDIA cards will cause latency spikes and should not be used for machine control, but i have plenty of GTX1060 and GTX1070 that are usable with NOVEAU drivers, older ones will mess latency badly, and even the ones i have on some motherboards do cause issues, so it's a cr@p shoot.
First, fix the ethernet latency, disable power saving options in BIOS and hyperthreading and TPM and..., then we can see what still needs to be done.

Seems like wiring issue, hal and ini seem fine, looked twice, but i do wear glasses ...

I don't think the video is an issue as it would show up in the generic latency tests.
 

The hal/ini files seem right

Short or other error in the cabling?

If you have the latest mesaflash you can:

mesaflash --device ethernet --addr 10.10.10.10 --dbname1 hdr26 --readhmid

(if you want the 26 pin IDC wire numbers)

If things still don't work, you might disconnect your cable
and check if the expected 7I92TF DIR pins change state
when jogging in different directions.
 

I have a nvidia 610 video card, should I replace nouveau with the proprietary nvidia driver? (I already did it in theory)
