Finally a fog-free night…
After tighten the DEC axis stiction a little bit (I loosened it too much), my GEM28 shows again very well performance, constantly. So, for the moment I’ll keep the belt tension as it is.
And no crash or freeze during the whole session 🙂
But I’m almost sure it will crash again. I suspect the error somewhere in the MGEN environment… maybe I’ll re-upgrade the MGEN firmware for the next session.
