Rich,
Thanks for your answer.
All the help on this forum is great.
Changing the values is also explained in the manual of mach3 (which i read over and over again)
But I was wondering if there is a possibility to connect these values to a "trim-pot", and then pick a value by turning the trim-pot.
The answers from Hood already explained that it is not possible to go higher or lower,,, you just cycle through all the values. It is not possible to go one step higher, and then one step lower again. You have to go all the way up or down.
Or is there another way of doing so??
