Bob after you put that one out I went and checked what mine was set for. It is already 50 px so that was that. I note there is a claibrstion step count setting which I just noticed. Mine is at 12. Edwin maybe you need to increase this. These settings are under Guiding/advanced.
I have issues in Dec with warning due to Dec backlash. This is a fact of life with these mounts. I suggest Edwin go through a backlash adjusent in his iexos. I can't say why his pulse guiding works but his automatic cal doesn't....perhaps manual pulse guide allowed larger steps.
