After some time spent in storage, I am doing some modifications to my Bartelized Dobson (10"Newt), in encoder area.
Vertical axis is first, I added 3D printed timing pulley and a bit of up-gearing, to achieve 6600 ticks per 360° (Ek's interface).
The idea is to avoid friction coupling -it was OK, but because the driving plate was also friction-coupled, it was tricky to adjust frictions such that encoder reading is reliable
