Does anyone know of an INDI compatible servo controller for a heavy duty mount (> 100kg optical load)?

Until recently the mount of our public observatory has been driven by 4A stepper motors and a Littlefoot stepper controller. The latter has given up working and we are looking for a new controller.

Since the maximum slew speed with the steppers is only about 60x we intend to change to a closed loop servo motor system such as the SiTech Servo Controller II (scroll down to => Servo Controller II ). However, the SiTech Servo Controller II at this time seems not to be supported by INDI. (There is a document on the Sidereal Technology Servo Controller Command Set which probably could be the base for driver development. )

If anyone has any experience with the SiTech or any other (preferably INDI supported) servo controller please tell us.

Why don't you write an INDI driver for the servo controller in a new mount driver?

We are still investigating on the amount of work and money that has to be invested in the change from stepper to servo motors.
Until now no other servo controller but the Sitech Controller II has shown up but at least we found an installation in Germany which we contacted in the meantime.
In case we decide to go for the SiTech we will certainly tackled the driver issue!

Hi Michael,
hopefully there is something to come here: www.campussternwarte.de/freego2.html
It seems they are still in "beta" but specs look promising.

Hi Andreas,
thanks for Your information.
I had come across their homepage a couple of months ago, and after Your hint, returned there.
It does look promising. However, they seem to be still working on their beta version.
Definite technical data I could not find and INDI support is not mentioned, either.
So, at present, it is not really an option for our publicly supported observatory.
