Hi,
I'm developing a new focuser to my refractor. It use push pull screws to move the focuser drawer tube. I 3D-print the different items I need.
It's a 3" focuser and a NEMA 17 stepper motor. It's designed for up to 5 kg load. You can read about it here, from page 12 to 14:
www.astrofriend.eu/astronomy/projects/pr...-focus-friction.html
I'm now ready to start with the controller board for the stepper motor but I don't know where to start.
I use Astroberry and the controller must use some INDI driver.
It must be flexible, I have read about Arduino that many people use. Some standard board that contain the drivers for stepper motor. Something simular that I use in my 3D-printer but smaller.
It must be an open source.
I only controll it from Astroberry, but there can be a focus out and a focus in button for test purposes.
Maybe ready for a micro switch that sense when it is at zero focus position.
Now my question, where do I found the best open source controller project. Instructions what hardware to use, how to install software etc ? I have never worked with an Arduino so it must have the details how to do it.
