Unexpected Realtime Delay on task 0.... was created by mundele
Building a PrintNC gantry style wood (and aluminum) router. I've got it homed and moving and etc. fine tuning some resonance or "herky jerkiness" but making progress. I've been nagged by and ignoring the error message in the title (unexpected realtime delay). I'm running an Intel NUC that's got a quad-core pentium
Intel® Pentium® Processor N3700 (2M Cache, up to 2.40 GHz)
I've :
Getting discouraged by that error. I am running a Mesa 7i96 which I had hoped would kill need for better latency. Yesterday I re-did config with PncConf... was helpful, my step timing was needing some adjustment and the tuner was helpful til I got to my tandem Y axis
. My Z still has some issues but better.
on that second PncConf run it set the servo period to 1098387 (which was my max latency in the latency test).
BTW I have a Gen7 i5 NUC as well, had assumed it'd be worse since it's newer. should I try it?
Any thoughts.
- Disabled everything in the bios I could think of
- Tried the "isolcpus" grub parameter to use only one CPU
- Played with doubling the servo_period

Did you disable all speed switching and all CStates above 1 in the BIOS?
Also if the NUC has an Intel Ethernet chip, you must disable
IRQ coalescing. This is described in the hm2_eth manual page:
man hm2_eth

I did set CState=1 in the grub config.. I didn't do anything to irq coalescing.

So i googled that (not at the linux machine to look at the MAN page) and the online copy of the man page says "Marvel chipset". Didn't know they had branched out from comics... Is that a typo and should it say Intel?
I've got a physical A/B switch (rotary switch) that I am using to switch between the Mesa card and access to my network. I have to use the WICD (?) debian network control to disconnect/reconnect each time. My Mesa card is on the 10.10 network and my local network is 192.168. I was seeing latency before adding the switch and I'm hoping since it's a physical piece of electrical hardware it won't add any latency issues.
I'll go back through the man page when I get back to the machine. Thank you so much for the help!!

Not sure if Marvell driver has the IRQ coalescing option or not
Pinging the Mesa card will give you an idea how the Ethernet is performing
As far as network access goes, I would add a USB/Ethernet dongle
so you don't need to switch back and forth. You will need to install
the network manager (to replace the very broken WICD which cannot
successfully setup dual Ethernet interfaces)

I had bought a dongle and never got it working. Maybe that was my issue. Will try that tomorrow.

Tried two separate dongles and could never get them working. In the process i uninstalled WICD and installed network-manager. Much better. I was able to script nmcli to swap networks via a shell script. Still using the switchbox.
In the process I removed that /etc/network/interfaces section that held the IRQ change.. Still seems to be fast ping-wise and latency wise although I'm still getting the error
My Z acts funky too. maybe my step rate is wrong or ? it does the herky jerky thing (X and Y are much better now) and often will overshoot the max endstop. I get Z Following Errors a lot too.

In the process I removed that /etc/network/interfaces section that held the IRQ change.. Still seems to be fast ping-wise and latency wise although I'm still getting the error
My Z acts funky too. maybe my step rate is wrong or ? it does the herky jerky thing (X and Y are much better now) and often will overshoot the max endstop. I get Z Following Errors a lot too.

Those ave very good numbers but I suspect the test did not run long enough to get realistic numbers.
If you still get real time errors, you can try doubling the servo thread period (to 2000000)
if you do this you should also change all the PID "P" values to 500
