Hi
Im uppgrading Triac 1986 to mach3. The X and Y movment works perfekt but i got problem wiht the Z movment. Is there anyone who know if there is any differences between SD2 and SD3 inputs.

I shall rebuild my triac 1986 to Mach 3. I wonder how the Boost and Energize control signals are used to the stepper board.
