linuxcnc Latency test ambiguous results

 
this is with my new kernel parameter. Youtube and stress test on.

I have these kernel parameters set "quiet isolcpus=2,3 acpi_irq_nobalance noirqbalance irqaffinity=0 processor.max_cstate=0 intel_idle.max_cstate=1"
From what I remember, better results are when you isolate 3rd and 4th core.
The "stress" test should not affect core 3 and 4.

You have integrated VGA i have a NVIDIA 610 i think is this the cause of high latency , my motherboard don't have vga output!
can you try use Rustdesk remote desktop with youtube video and try another time latency test?

I don't use remote desktop. I did a test with three working youtube videos

No, not yet.
Now is that point where you upload your configuration files here so we can have a look, joint errors are usually miss configuration on stepper systems.
What board are you using?

Hi tommylight, have you seen my configuration? is a default conf.

Yes i have, but not a default config, it is for NV something or another.
Do you get the dropped connection?
Do you get joint errors?
 

No the connection is stable( joint error only 3 video Youtube+stresstest+rustdesk remote desktop) but i have bad stepper movement.
Try to put:
[JOINT_1]
DIRSETUP   = 150000
DIRHOLD    = 150000
STEPLEN    = 150000
STEPSPACE  = 150000

 and

[STEPGEN]
#150000
DIRSETUP   = 150000
DIRHOLD    = 150000
STEPLEN    = 150000
STEPSPACE  = 150000

and
[STEPGEN]
#150000
STEPGEN_DIRSETUP   = 150000
STEPGEN_DIRHOLD    = 150000
STEPGEN_STEPLEN    = 150000
STEPGEN_STEPSPACE  = 150000

and 

[STEPGEN]
#150000
STEPGEN_1_DIRSETUP   = 150000
STEPGEN_1_DIRHOLD    = 150000
STEPGEN_1_STEPLEN    = 150000
STEPGEN_1_STEPSPACE  = 150000

my driver is a  TB6560 (only for testing not final hardware)
all conf not change the movement



the work is linuxcnc classic engrave test

As you have it it is way to long so it limits the max velocity a lot and can cause joint errors, depending on the scale and velocity set in the ini file.

need this???
#150000
DIRSETUP = 150000
DIRHOLD = 150000
STEPLEN = 5000
STEPSPACE = 5000

same of the conf with:
#DIRSETUP = 150000
#DIRHOLD = 150000
#STEPLEN = 5000
#STEPSPACE = 5000

I don't understand if I have to add something about the hal file, I found this:
linuxcnc.org/docs/stable/html/man/man9/stepgen.9.html
stepgen.1.dirsetup
stepgen.1.dirhold
stepgen.1.steplen
stepgen.1.stepspace

I also found this but I don't know where to put the parameters, I know that this gui is only for the parallel port or am I wrong?
