Solution fo "hm2 error finishing read" with no good PC

 
 
 

r8168-dkms drive is it installed ?

Can you run this script:



and post the results here?

first make executable with:

chmod +x edrivers.txt

then

./edrivers.txt
 

This is what i get:

i get like before

My PC is a Dell Optiflex 3040

So looks like the DKMS driver (I think the default driver with latency issues "8169")

So not sure whats going on.

What does your kernel command line look like?

cat /proc/cmdline



 

the command return to me :

Did you try pinning the Ethernet IRQ?

As a test you can run this script:

 

chmod +x pinirq.txt then:

sudo ./pinirq.txt enp2s0

And then retry LinuxCNC or the ping test

I need your help because I'm completely lost.

as at the beginning of this topic, i had an “hm2 error finishing read” problem.
i took the pc to feed a 7i96s i never have the “finishing read” problem.
i bought a new computer with much better latency and constant ping.
I plug in my lathe and it displays “hm2 error finishing read” all time when i ask change tool on my turret and somethime when i enable the drive (F2)...

before :


it used to work fine but now the turret runs for 1 second with this error... and I haven't changed a thing since.

below is the histogram of the new pc

 
 
 

If you only get the error when enabling some motion it may be an EMI issue
Is the 7I96S's frame ground connected to chassis ground?

Also can you report the result of:

sudo chrt 99 ping -i .001 -q -c 60000 10.10.10.10

( This assumes the card IP address is 10.10.10.10 )

The test will take 1 minute
