Baader Steekdrive Diamond and 0.2291 setting on SteelTrack Focuser Motor Drive

[Adrian Condon]

Hi,

I have purchased a Baader Diamond SteelDrive with the SteelTrack Focuser Motor Drive for my 10" Orion Optics uk Dob.....

I have it all installed and now in the process of getting it to work on the hand controller.

I have put Custom in the Model set-up, the instructions in Section 4 of the manual state......"for Steeldrive Diamond, please select Custom and specify a gear ratio of 0.2291"

Great,  how do you set the 0.2291 on the hand controller?????????       

When I do the POS. CAL    the focuser goes to 28.2mm instead of 25.00mm as stated in the instructions. (I suspect the measurement is incorrect because I cannot enter the 0.2291 figure....)

Offers of help gratefully appreciated....

Cheers

Adrian
