A good working motor focuser is important to get good quality photos. I make small improvements year after year. But now starting all over from the beginning and make a focuser that I have designed. It's a 3D-printed focuser and now I'm building the focuser controller based on the open source project MyFocuserPro2.
Here is my project:

Maybe I can do some desk test of it this week. Looks promising.
