Thank you. This project is so fragmented with so many versions and ways to build it, people is reluctant to try it. I couldn't figure out where to start and follow until I found your video. I just saved hundreds of dollars on silly motorized focuser technology 😁 THANKS!
Gracias por esté video, después de tantos años todavía tiene éxito,por lo menos para mí, he conseguido hacer todas las conexiones pero algo falla, el motor da vueltas solo en un sentido y no tiene mucha fuerza,lo paro con la mano. Algún consejo ? Gracias
I know this video dates back a few years but I'm following your design. The question I have is that you say you use a PG5 stepper (gear ratio 5:1), but in the video and the link, it's a PG27 (gear ratio 27). I see from the project documentation that both can be used but which one did you actually use and why?
Hi amazing video a tried it but the driver board overheating burned my finger and I can’t get the stepper to move on the app it shows like it is moving but in reality nothing happens can you suggest something thanks!
Hi Astro Just after a bit of help or advice my duiamilanova board connects to myprofocuser 2 and Ascom and APT they all come and say connected but when I put a number steps the stepper does not move I have done the continuity test for pairs of wires and all ok. Just wondered if you may have any ideas. cheers John
i cannot find this version of the code anymore. the one available now is just the complete version. Any possibility of getting the older version so i can follow the video as is. The latest version i think requires a special PCB.
Why not just use an Arduino Uno with a stepper motor shield and a single DRV8825 board? A little more money but you eliminate all of that nasty wiring. BTW, I am looking for a similar tutorial for the Arduino and a ULN2003 board have you seen this anywhere? I need to use a unipolar stepper because it fits in the dedicated focuser that I 3D printed for my Orion ED80T-CF refractor. BTW, invest in a heat shrink tubing kit. Inexpensive, safer and cleaner.

THANKS!
For anyone looking for those 2-pin screw-together power connectors, they're typically called aviation connectors.
Very well done, well explained, thanks for taking the time to share your knowledge and experience, it's appreciated 👍
Really helpful. Thank-you for your time and effort.
Excellent video. Never tried arduino. I'll give it a try💪
Great video! This was perfect timing for me as I'm just about to start doing this myself. Thanks!!

Gracias
Great idea and service Alexei!
Very well done thank you.
great tutorial
Thank you man! Great work!
love the video i need help choosing a motor i need for this project my scope id a skywatcher 200pds it has the duel speed focuser on it

what did you say you used to attach the motor to your telescope tube without drilling?
Great work, thank you!
Great video mate cheers
Is it possible to install the motor on the focuser shaft without the planetary gearbox?

What are the stepper motor connectors called?
Very useful video!Can I transfer your video to Chinese channel, I will indicate the source from you.
Muito bom

I have the same problem. Did you ever figure out what was wrong with yours?
i cannot find this version of the code anymore. the one available now is just the complete version. Any possibility of getting the older version so i can follow the video as is. The latest version i think requires a special PCB.
Hi Did you manage to work out what files to download? Im planning on building this and just realised the file isn't available anymore!

Whats the maths behind the 0.245a? Your motor is a 0.4a and you set the stepper up at 0.245. I’m kinda confused 🤔
Wish I could remember :/
