Errors caused by Latency or something else?

oh woops, didn't realize the difference, til I saw the 27.1 from the previous.
I found the gears animation thing, and just opened 8 of them to stress, could that have caused it? I didn't run the animation on the first one, I just opened a bunch of programs, and began creating big pictures in gimp.
Im I just messing up information? :(

Ran histogram again this morning, and this time I get min(us): -34.5 and max(us):35.5
I have to ask, how does these correspond to the normal latency test numbers?

is 35 us equol to 35000 ns?

also, what do you guys do under the latency test? just use a couple of programs, or a lot?

I feel like i'm at a dead end. That the next step is to try a different computer, or another nc solution entirely.

35uS = 35000nS = 0.035mS

What network adaptor do you have? Did you see the comment from PCW
"Also what host PC hardware are you running? If you have a Intel or Qualcom MAC you must make some driver setting adjustments with the ethtool utility"

Other options are, as you have suggested: A different motherboard (there are relatively cheap ones that are known to work fine) or switching to PCI hardware or a different controller.
Of those, the cheapest is likely to be a different motherboard. (as no other controllers are compatible with your hardware)

I have now found another computer(workshop pc) with an ssd too
Installed a fresh debian stretch preemt uspace install.
Made a fresh pncconfig config only setting it to lathe and metric, plus x and z stepgen.
I even grabbed a new Ethernet cable (since the old one wasn't long enough)
Set host ip to 10.10.10.1 and card ip to 10.10.10.10.

And I get the same two errors...:blink:
Even though this is progress, I want to smash my head into something!

So I guess its my Mesa card, my card setup, or maybe an incorrect way of connecting to the card?

As for PCW's question
Sorry, I read it, but didn't get the focus on Ethernet. thought it was more general hardware spec.
I snatched a lshw, hoping it will show more information about the Ethernet type and info. (This from the new, currently connected computer)

Hope you can use this information. I really appreciate you guys helping me!

Looks like Realtek

*-network
description: Ethernet interface
product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller
vendor: Realtek Semiconductor Co., Ltd.
physical id: 0

Is there any chance that the problem is W8 being in the "setup" position?

It should be in operate mode, left position (with Ethernet port in top left)

Here you go

(edit) I realise the ip is 192.168.1.121, but I have edited it to 10.10.10.10 everytime I used the config. this is a backup

change:
SERVO_PERIOD = 37900
to:
SERVO_PERIOD = 1000000
in your ini file

This should work a lot better...

Man... that kick you get when motors buzz and growl because of bad settings - when you weren't expecting anything to happend.

That did the trick! I am so happy and relieved right now! Thank you guys for the help!

I thought I was supposed to enter the latency test value in there? Pncconf did say recommended servo period : 1000000. But i thought it was the base value for some reason. Maybe because my values where that stupid high to begin with.

Thank you guys again! I can finally continue with the project again!
