QtPlasmac problems

There are some variables at the top of the shetcam post processor that allow you to prevent generation of the hole data if you don't want to use it.

Thanks Rod

Yes the hole processing variables are what I commented out in the g-code, the intention being to edit the PP as needed once I had proved it resolved the issue. I can confirm after setting the hole cutting variable in the PP  to = 0 all now works as expected.

Unfortunately the realtime comms problem is still evident. I have had 3 Ethernet leads so fairly sure that’s not the problem, the Ethernet nic is the only one now in the system so nothing there to interfere in any way. I have a static address, irq coalescing is disabled, the problem happens even when the plasma arc is not active so it’s not interference from that.
i never had any issues with realtime before the upgrade

Indicates relatively huge network latency (>5 ms if the watchdog setting is the default 5 ms)
That sounds like maybe a power management issue so you might try adding pcie_aspm=off
in your kernel command line.

What is the current kernel command line?
 (cat /proc/cmdline)



 

Thanks PCW.

At the moment all that’s in the kernel command line is quiet
I had previously tried to add an isolcpus=2, 3 using grub-Customizer but it messed up somehow and was forcing it to boot into tty which took a little time to work out and resolve.
I will add the power management in the file manually tomorrow and see if that resolves it. The pings are all low but as you say something must happen that causes some latency every so often

I added the pcie_aspm=off and also igb.EEE=0
while running latency-histogram the rt error occurred and the latency shot up massively, see attached.
i then added isolcpus=2,3. I have since done some cutting and not had the error since. Time will tell if that resolved it or not, but the massive increase in latency that came out of nowhere makes me think there is something else happening

 

That (>16 ms latency) seems like a power management issue or perhaps a hardware failure.
Are all power management, C States >C1 , Turbo modes etc disabled in the BIOS?
