Hi Pmrid
Welcome to the club (of bartelized scopes)
Your machine looks great!
As far as config.dat is concerned, we (Rod and myself) are still sane and sound.. and the thing even tracks !
I also do not use field rotation (this is only for photography anyway and I am using mine for visual at the moment.... for photography I will mount my newtonian on Bartelized EQ6 one day).
Focus control via PC is also somewhat too much of an overkill... but with the rest of the settings there were not so many troubles.
And I never bothered to fine tune microsteps, as I found the major source of un-smoothness of the motor rotation comes from the fact that the PC I am using has 100MHz processor (it should be at least 200MHz or over).
