[SOLVED]linuxcnc Latency test ambiguous results

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

STEPLEN = 150000
STEPSPACE = 150000
to
STEPLEN = 5000
STEPSPACE = 5000
or
STEPLEN = 10000
STEPSPACE = 10000
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?
