Changing Kernel Speed in Mach 4
« on: May 23, 2017, 11:42:03 PM »

Hello, I'm using mach 4 and ethernet smoothstepper.

I want to change kernel speed, but I cannot find the configuration menu.

It seems that there's a configuration menu on mach 3.





How can I find the menu on mach 4?

Hi,
to my knowledge there is no such page on Mach4 with ESS. Its the same combination I use and I've
never set the kernel speed in the same manner as Mach3 with PP.

Hi,
thinking a little more about your question...the kernel speed is the 'clock rate' of the internal
software driven timer used by Machs parallel port. With an external motion controller like the
ESS there is no timebase internal to Mach, the external controller will no doubt have a clock as a timebase.
The ESS has a max pulse rate of 4Mhz and guess that it is the equivalent of kernel speed. 4 MHz is way
way way quick...

No kernal speed in Mach4. The external pulse engine looks after that.
In Mach3 with external engine such as ESS you can leave it set at 25 kHz - it does not matter.
