Thanks for the hint.
This parameter is not quite the one i would have looked into. After i
changed it from 5000 to 10000 the pulse width changed from ~3,2µs to
~4µs. And with a value of 20000 i get ~7µs which is enough to work with
my old stepper driver. Interestingly when i set higher values the width
doesn't go over ~7µs but i can live with this setup for the moment.
I also ordered a few new stepper driver from omc-stepperonline.com
because they are so cheap i couldn't resist. Maybe it works better when
i have replaced my old hardware. :)
Ciao,

Subject: Re: [Emc-users] How to change step pulse width for stepper
driver
So i tried setting stepspace = 10000 but no change. Then i tried setting
both steplen and stepspace to 10000 and also no change. It seems as if
LinuxCNC ignores my values.
When i open HAL Meter and show the current value it shows me 75000 for
both of them. But this would mean 75s pulse width which i don't have.
It is still around 2,3s.
I attached my old confiurations and maybe someone can see what the
problem is. I don't know if i have to change something else for the
current version of LinuxCNC. I only know that the configs worked back
then when i last used them 15 years ago. :)
Ciao,

"setp parport.0.reset-time 5000"
is what is setting the step pulse length
When you use reset mode its normal to set steplength and stepspace to 1
