I use HSO in stepper mode ( on a T38 without PTO utilities like TR34) .
It's works nice in 4 stepper app (multiplex).
But when you set the HSO run MB the current Position is alqay set to 0 ... so you have to save it by hand , a little bit heavy ...
I didn't understant why unitronics didn't let the "Current position" as a "absolute" value , it would be more praticable ...
Or maybe i forgot somethings ...
thanks
