Motor focuser DIY

[Astrofriend]

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.

Today I could do a load test of the focuser. I loaded it with 5 kg and there was no problem for the stepper motor to handle that load.

Hi @Astrofriend

Thanks for the guide! It has been really helpful.

Now I am waiting for the actual motor as I have been testing with a tiny stepper.

Hi,

The last I did a couple of days ago was to replace the stepper motor with one with higher impedance.
