Re: Setting backlash Question

Khalid Baheyeldin

There is a simpler way to adjust backlash than what is in the Wiki.
No calculations needed ...

Basically, during daylight, use a faraway stationary terrestrial object.
For example a communication tower, a nail on a neighbour's chimney, or something like that.

Start OnStep normally, then slew to that object.
Turn off tracking.
Now using trial and error, try to refine how the object is centered when you move E and W.
If it jumps, then the backlash value is too high, reduce it.
If it lags, then the backlash value is too low, increase it.
Keep doing this until you don't observe any jump or lag when you reverse direction.

Repeat with N and S buttons for the other axis.
