I used SGP for the first time last Saturday night. I bought SGP mainly for autofocusing for now. I have a Starlight Instruments/Optec Handy Stepper Motor and Focus Boss II Hub. It connects fine with SGP. I am able to successfully run the “Sequence” including autofocusing.
If I enable backlash compensation (inward or outward), then I use Focus Control to move 1000 steps either direction, the motor moves and then stops communicating with SGP. I have to disconnect and then connect by clicking on disconnect/connect button for this focuser in SGP in order to resume communication. If I then disable backlash compensation, then it works fine.
If I use Optec’s software/driver to set backlash compensation and disable backlash compensation in SGP, it works fine but I am not sure if the actual backlash compensation actually happened.
I found the SGP log showing a bunch of error messages relating to this issue.
I have no other issues so far. Like I said earlier autofocusing works very well as long as SGP’s backlash compensation is disabled. I have sent an e-mail to Jeff Dickerman of Optec about this. I don’t think I’ll hear from him till Tuesday.
