And I have 2 of them here.

I am doing that on my lathe as it reduced the "noise" in the spindle encoders output considerably, but I can run a 23 u-s base_thread, getting one such message after many hours. Disappears at a 24 u-s base_thread, 22 might get me one in 30 minutes. > Other than that those are great boards and they still are my > choice for LinuxCNC machines. > > Viesturs Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
