Guidance Needed! Initial LinuxCNC/PncConf setup

Maybe its a thermal issue on the host?

Meaning my LCNC computer may be getting too hot? 

So can I assume that the info I provided above is within acceptable parameters and has narrowed things down to a possible thermal issue?

Thanks

I'm just guessing a thermal issue because of the behavior.

There really is nothing that should go bad with Ethernet
latency that should require a reboot to restore.

Alright. Thanks for your help.

I will blow the computer out and watch the temp and see if that helps.

I read the following in another thread that the OP was having the same error message.

Oops yes P gains should be 500 for a 2 ms servo thread

My servo thread is set to 2 ms but I did not change the P gains. Should I do this as well?

Yes (though its not going to affect the communications issues)

OK. Thanks

The error indicated by the LED is a watchdog bite,
This is cleared when LinuxCNC starts. Sounds like it bites
again due to latency issues.

I have done further testing and can confirm that when I get the "Error Finishing Read" error I can now close LCNC and reopen it and the error is cleared and I am able to use LCNC. Not sure exactly what I did to get it to work but I will take the win.

I do still get that error popping up randomly. It seems to happen most when the machine is idle and the machine toggled ON. 

I have been fine tuning my axes and have noticed a chatter of sorts when I am jogging full length of the axes. It almost seems like it is missing steps or something. I have only noticed it on the X and Y axes so far as I have hey to fully test the Z. What should I be checking?

After reading some other threads I started with testing a different keyboard. That did not help. BUT I do notice that when I use the mouse and just click and hold the -/+ buttons on the Manual Control screen I do not notice as much stutter, if any. When I say "if any" that is because I do hear/feel something very slight occasionally when jogging. But I cannot tell if it is motor related or maybe coming from the ballscrew. It kinda sounds like it may be a tiny binding sound or something.

Not sure what to check or how at this point. Any thoughts?

Also, the keyboards I have seem to cause/exacerbate the stuttering issue. Are there any recommended keyboards that are known to work?

After reading more threads I ended up trying "xset -r" and that seemed to minimize/eliminate the stuttering when using the keyboard.

Can someone tell me how to disable this exactly?

Thanks
