Supported Focuser type

Sequence Generator

Hi, I have read the help file re supported focusers and it mentions ‘any focuser that provides an ASCOM compliant driver’.

I’m writing an ASCOM driver and my question is just to check if SGP supports both absolute and relative focusers and also if there’s any advantage of writing the driver for one type (absolute or relative).

thanks for thoughts.

It is true that SGPro will connect to and provide a control interface to any focuser with an ASCOM driver, but you will not be able to use Auto Focus unless the driver is compatible with the ASCOM Absolute Focuser contract. Several relative motors write drivers such that they fake being an absolute driver though.

Thanks Ken, that helps me, I’ll build an absolute version.
