i was for two weeks offline because of holiday, so first super thanks for your reaction
i would apprised, the posibility to have the stepper OnFocus driver for indi. I use the Arduino uno with the stepper as described
on www.stellarjourney.com/index.php?r=site/software_focuser
and github.com/hjd1964/OnFocus, learn.sparkfun.com/tutorials/big-easy-driver-hookup-guide its very simple autofocus to build see spark fun site the final circuit.

it for me blocking issue to proceed with indi.
The aim for me to use indi, i like build a remote setup on the other site of the country

i found the other Arduino stuf but that is not compatible. let me know when you are able to program something so i can test. Thanks on for hand

hi!
i adopted an arduino sketsh from hansastro.io and made a small PCB - this one drives now my feathertouch, and the Lacerta OctoFoc and a Moonlite Focuser of colleagues - works like a charm with INDI ... do you want to take a look at that stuff?

Please share the information as long its not working (driver not there) i must build next to my windows setup a second hardware setup to get it working.
although i have still some other hardware which is working with the robofocus driver on windows, i must check if this is also working, i discover in indi this driver also.

But anyway it is interesting not only for me but for a other user on this forum, if you can share this information. Thanks on forehand.

hi!
well, you need an arduino nano and a A4988 driver basically - here is the page i referred to: hansastro.github.io/Focuser/

this sketch works fine with INDI. I also made a PCB for that focuser - see attachment.

Hi Wolfi,

I just built the Hansastro focuser, I can connect to a version with Arduino Uno, not to a Nano. The display and motor work on both.
But I can connect to the Uno under Windows with the Moonlite Single Channel Controller, not to the Nano.
Could that be due to the USB chip of the Nano? But you have it working I understand?

I wil test under Linux with Ekos, hope that will work.

Regards,
Albert

Hi! Only trìed ekos ... how can i help? Lg wolfi

The Nano USB port will do a reset when you open the serial line (to get it in clear state); To start communication it need a ~2 second delay. The Moonlite software under Windows does not wait for that and communication fails ... You can avoid this by soldering a capacitor somewhere between 2 pins but then you need a switch to disable it or you can't download new firmware. It is well described in the MyFocuser project. (Not the MyFocuser2, that is not Moonlite compatible)
(Excellent focuser software and design)

Hi as far as the windows protocol is concerned, i have not tried it. there is one issue - i do not use the temperature sensor,and i do not use the display. if you do, there might be a problem because the temperature sensor is connected to A4 in the original sketch, which is also a I2C pin for the display. i changed that to A0, but as said, i do not use the display or the sensor. i can send you my modified sketch. this works fine with EKOS ...

Thanks Wolfi,

The display and sensor work, the sensor is on A3 now, this had been changed in the Arduino sketch by Hansastro.
I will have to test on Ekos, so far I am a Windows user, but I want to escape!
But I need to connect a camera first, or Ekos will not start.

Regards,
Albert

hi!
as said before, i did not encounter that problem with Linux...

Correct. The Indi Moonlite (an others) driver retries and that solves the problem (or has a time-out) The original Moonlite driver on Windows does not wait long enough for the communication to start.

Rgrds,
